La Union (Tagalog pronunciation:[lɐʔʊˈɲon]), officially theProvince of La Union (Ilocano:Probinsia ti La Unión;Pangasinan:Luyag na La Unión;Kankanaey:Probinsya di La Unión;Ibaloi:Probinsya ni La Unión;Tagalog:Lalawigan ng La Unión;Spanish:Provincia de La Unión), is a coastal province in thePhilippines situated in theIlocos Region on the island ofLuzon. The province's capital, theCity of San Fernando, is the most populous city in La Union and serves as the regional center of the Ilocos Region.
Bordered byIlocos Sur to its north,Benguet to its east, andPangasinan to its south, with theSouth China Sea to the west, La Union is located 273 kilometers (170 miles) north of Metro Manila and 57 kilometers (35 miles) northwest ofBaguio City. The province spans an area of 1,497.70 square kilometers (578.27 square miles). As of the 2020 census, La Union had a population of 822,352, resulting in a density of 550 inhabitants per square kilometer or 1,400 persons per square mile. The province had 538,730 registered voters as of 2022. The province official language isIloco (Ilocano), as declared by the provincial government of La Union.
In the northern section, early settlements were established along the coastal plains ofPurao (nowBalaoan),Darigayos, and the areas surrounding theAmburayan River.[6] These settlements were primarily inhabited by theSamtoy (Ilocanos).[7] HistorianWilliam Henry Scott documented that Balaoan was historically referred to as being"rich in gold" due to its proximity to the gold mines in theCordillera region.[4] The town served as an emporium for the exchange of Igorot gold through barter and trade among lowlanders, highlanders, and foreign merchants inTagudin.[3] Similarly,Baratao (nowBauang) has been identified by historians as a settlement of comparable importance to Purao as emporium of gold mines.[3]
In the southern section, the areas ofAgoo and Aringuey (nowAringay) were early settlements of the Pangasinenses.[5][4] Agoo functioned as a trading port withSual as its only rival. Agoo was frequented byJapanese andChinese ships, whose merchants engaged in commerce or barteredgold with natives.[5] Aringuey served as a coastal maritime trading hub and the terminus of theAringay-Tonglo-Balatok gold trail, located along the delta of the Aringay (Ifugao) River.[8] This route facilitated the transport of gold from theIbaloi villages ofAcupan andBalatok in the southern areas of present-dayBenguet to the trading centers of Aringay, with further distribution to the port settlement of Agoo.[8]
These trading activities were part of a larger maritime exchange network that extended across theIndian Ocean and theSouth China Sea.[8] Products exchanged within this network includedporcelain,silk,cotton,beeswax,gems,beads, and preciousminerals, withgold being a significant commodity.[8] Artifacts like porcelain and pottery, uncovered during the renovation of the Catholic church in Agoo and now housed in theMuseo de Iloko, testify to this trade activity.[5]
In June 1572, Spanish explorers led by conquistadorJuan de Salcedo, the grandson of Miguel López de Legazpi, launched an expedition northward and founded several Spanish settlements, including those in theIlocos region and the city ofVigan.[4]
By 1575, Salcedo navigated the Angalacan River to theLingayen Gulf in pursuit ofLimahong, a Chinese pirate who had fled toPangasinan after his fleet was driven away fromManila in 1574. There, they encountered and attacked three Japanese ships, mistakenly identifying them as part of Limahong’s fleet.[10][5]
After the ships retreated, Salcedo pursued them and arrived at a Japanese port inAgoo.[3][5] The Japanese mercenaries and local natives were subjugated and required to pay tribute to the Spanish Crown.[11] Although some initially resisted, those who complied were allowed to remain.[12] This encounter earned Agoo the title"El Puerto de Japón" (Japanese Port) from Miguel de Loarca in 1582, as it had long served as a hub for trade among Japanese and Chinese merchants and local natives.[13][14]
Salcedo continued his expedition northward and arrived at what is nowSan Fernando.[15] When he demanded tribute from the natives, they sought permission to ascend the mountains to gather their offerings but failed to return.[3] Salcedo then proceeded toAtuley (modern-daySan Juan) and further north until they encountered a large Ilocano settlement called "Purao," referring to the gleaming white sands of its beaches along theSouth China Sea.[9]

When the natives of Purao refused to pay tribute, it led to the first recorded conflict in theIlocos region,[9] known as theBattle of Purao.[16][9] This encounter resulted in the shedding of the first Ilocano blood in defiance of foreign rule. The river "Purao" was later renamed"Darigayos," derived from theIloco words"dara" (blood) and"ayos" (flowed), meaning"where blood flowed."[15] Continuing his journey, Salcedo arrived at Bigan (nowVigan), a settlement of Chinese traders, and formally established it asVilla Fernandina de Vigan in honor of Prince Ferdinand, the son ofKing Philip II of Spain.[9][17][15]
By the 17th century, the Spanish had established settlements, orpueblos, organized into sitios and rancherias, in Igorot land in La Union. These were governed by agobernadorcillo,alcalde-mayor andcabeza de barangay, with many of these settlements established byAugustinian friars during the 16th century's expansion phase.
Society during this period was divided into two classes: the babaknang and the cailianes. Thebaknang orbabaknang means"the rich" andagtuturay oragturay refers to"the powers-that be" or"the authorities." Propertied, landed, and educated, they formed the local elite class or were theprincipalia orinsulares who spokeCastilian, On the other hand, the unlearnedcailianes had less or no property that spokeIloco,Pangasinan,Kankanai andIbaloi. Iloco served as the province'slingua franca.[18]
The Spaniards' search for gold (oro) inIgorot territories fueled their expeditions. Religious orders were also motivated by opportunities for missionary work.[19] By 1620, however, the gold trade had begun to decline in the province including the Aringay-Balatok-Tonglo, Bauang and Bangar gold trails.Captain Garcia de Aldana led expeditions into areas likeAringay,Bauang, andSan Juan, whileSargento Mayor y Capitan Alonso Martin Quirante centralized the industry in 1624, deploying a force of 1,748 troops, includingSpaniards, Chinese, Japanese,Mexicans, and 500 Ilocanos.[4] Natives and mercenaries were often faced harassments forced to reveal gold sources.[20] Many converted to Christianity to avoid persecution, while others fled to the Cordilleras.[citation needed]
In 1661,Andrés Malong of Pangasinan, who declared himself king, led a rebellion against Spanish colonial rule in an attempt to liberate several areas in the northern pueblos of Pangasinan and theIlocos provinces.[3] As part of his campaign, Malong sought to reclaimAgoo from Spanish control. However, his forces, consisting ofPangasinenses,Zambals, andNegritos, suffered a decisive defeat during theBattle of Agoo. The Spanish, with their superior weaponry and strategic fortifications, successfully repelled the rebellion.[21]
In the early 1700s, Spanish missions inAgoo,Bauang, andBacnotan aimed to convert resettled Igorots through the Spanishreducción policy, which subjected natives to harsh treatment.[4] By 1739, friars discovered thatBangar engaged in barter trade with the Igorots in the east. Smuggling became rampant under theTobacco Monopoly in the late 1700s, impacting Spanish revenues significantly by 1788. Despite Spanish efforts to control the highlands, the Igorots retained their autonomy well into the 19th century.[3]
In 1754, Igorot chieftainLacaaden of Bukiagan (now part ofTubao) negotiated with the Spaniards to avoid punitive expeditions by requesting missionaries for his people.[22] This led to thebaptism of Igorot chieftain inTondo underGovernor-General Pedro Manuel de Arandía Santisteban[3]. However, resistance resumed in 1759, prompting PangasinanGovernor Arza to launch a military campaign. On 18 March, Lacaaden led a five-hour battle against Spanish forces armed with rifles and artillery. The Igorots held their ground, forcing the Spaniards to retreat along what is now Naguilian Highway, burning villages along the way.[22]
Diego Silang Monument inCaba, historically part ofAringay, Pangasinan province, his birthplace.
The town ofCaba became notable as the birthplace ofDiego Silang, leader of theIlocos Revolt (1762–1765) during theBritish occupation of Manila. Silang persuaded the gobernadorcillo of Balaoan to encourage Ilocanos and Igorots in the town to join his anti-British struggle, which extended to the revolt inVigan.
In 1820, Don Agustin de Valencia, thegobernadorcillo of Bangar, and Don Agustin Decdec, an Igorot chieftain from Kayan, together with other Igorot leaders from Bacong and Cagubatan inTagudin, formalized an Ilocano-Igorotbodong (peace pact).[23] This agreement, facilitated by theCapitanes Pasados, reinstated highland-lowland trade, which had been disrupted three years earlier due to the killing of an Igorot in Tagudin and the subsequent retaliatory killing of an Ilocano from Bangar.[4][23]
By 1826, the Spanish established theCommandancia del Pais de Ygorrotes y Partido del Norte de Pangasinan to combat tobacco smuggling.[24] Lieutenant Colonel Guillermo Galvey led campaigns into the Cordilleras, using towns like Agoo, Bauang, Bacnotan, and San Juan as military bases.[3]
Baluarte Watch Tower, Luna
San Juan Watchtower, La Union
400-year-old Spanish-era watchtowers built to guard against tirongs (pirates) along the coastal settlements of La Union
From 18th to 19th century the coastal towns frequently faced raids byMoro marauders locally known astirongs (raiders, attackers, pirates) andChinese pirates, who looted barrios or villages and captured women and children. To counter these attacks, the Spaniards built circular adobewatchtowers, orbaluartes, in 1836.[25] These structures, ranging from 6 to 7 meters in height, were constructed along the coastline in towns such asNamacpacan (Luna),Balaoan,San Fernando, andBauang. These baluartes played a crucial role in protecting coastal settlements and securing trade routes throughout the 19th century.[26]
La Union was officially established on 2 March 1850, through the unification of territories from the provinces ofIlocos Sur,Pangasinan, and theCordillera, making it the 34th province of the Philippines.[3] AfterCebu became the firstprovincia in 1565, new provinces have been created by the Spaniards. Three main functions were considered so:Political-Civil Administration, Ecclesiastical governance and Geographical considerations. For more than two and one-half centuries, the originalIlocos province remained intact until 1818 when it split intollocos Norte andIlocos Sur. In 1846,Abra was created by Governor General Narciso Zaldua Claveria.
Governor General Narciso Zaldua Claveria was a visionary administrator who recognized the need for innovative solutions to address the demands of political and civil administration. He proposed combining three contiguous areas that were far from their respective provincial capitals, seeing it as a viable approach to improve governance. Claveria also recognized the agricultural and commercial potential of the territory. Moreover, he saw this initiative as an opportunity to extendHispanic civilization andChristianity to the area.[3]
Distance posed significant challenges to local administration. FromVigan, the capital of Ilocos Sur, the three southernmost pueblos (Balaoan,Namacpacan, andBangar) were located approximately 13 to 14 hours away on foot. Thecailianes and thebabaknang often complained about the physical distance from their officials in the cabecera or capital town.[3] Similarly, fromLingayen, the capital of Pangasinan, the nine northern pueblos (Santo Tomas,Agoo,Aringay,Cava,Bauang,Naguilian,San Fernando,San Juan, andBacnotan) were also burdened by the 13 ½ hours of travel required from Bacnotan.[3]
The situation was even worse for the 40 to 45rancherías located in the depths of theEastern País del Igorotes. Thecommandancia established in 1826 proved ineffective in maintaining order among the Igorrotes, whose remoteness from central authorities led to rampant smuggling of tobacco and other merchandise, thereby disrupting the region's economic stability.[3][27]

Thus on 29 October 1849, Governor General Claveria signed thepromovido (proposal) to unite thePangasinan-Ilocos-Cordillera areas into a new province called La Union (the official name designated by Claveria himself) as San Fernando ascabecera (capital) andAmburayan River in the north and Rabon River in the south as provincial boundaries. For 124 days, high and important Spanish colonial officers studied and deliberated on the proposition to create La Union or not.
On 2 March 1850, Governor General Antonio María Blanco signed the superior decreto that founded La Union – the 34th province since the founding of Cebu in 1565. It was classified as aGobierno Politico-Militar (Political-Military Government). Blanco appointed, on 4 March 1850,Captain Toribio Ruiz de la Escalera (Claveria's former trusted aide de camp) as the first Gobernador Military y Politico. La Union is the union of lands, people, cultures and resources. On 18 April 1854,Queen Isabella II of Spain issued thereal orden (royal decree) fromMadrid confirming Blanco's superior decreto.[3][27]
By 1869 and 1885Rosario andTubao became towns in La Union respectively. In 1869,Governor-General de la Torre converted Concepcion into Rosario, which remained spiritually dependent on Santo Tomas. Despite the bishop's refusal to assign an assistant priest, Rosario became the 13th town, with its priest overseeing both towns.[27] In 1885, after 12 years of petitions, Tubao was officially recognized as the 14th town asSan Isidro de Tubao, named after the patron saint of farmers.[28]
By 1860, there was significant progress in commerce and agriculture in the province. La Union became an exporter oftobacco,rice, andsibucao from the 1860s to the 1880s.[3] Tobacco was the primary product and the reason for the province's economic growth. Spanish authorities relied heavily on the prized leaf for further economic development. The industry was so lucrative that aTobacco Monopoly was established. All tobacco leaves were strictly monitored and purchased exclusively by the government at a fixed price.[3]
Simultaneously, other provinces were also experiencing economic growth. Relying on its own indigenous resources, La Union did not import rice, palay, tobacco, sibucao, or other products during this period.[3]
By 1887, the province's population had grown to 100,775. La Union's heterogeneous population mingled throughout this period. The Chinos, orMestizos de Sangley,Españoles-Peninsulares, andEspañoles-Insulares coexisted with the nativePangasinenses,Ilocanos, andIgorots (particuallaly theKankanai andIbaloi), whether Christianized or non-Christianized. The Christianized Igorots orNuevo Cristianos were often referred to asVagos orBago.[3]
Gobernadores Politico-Militares of La Union (1850–1898)
The following is a list of SpanishGobernadores Politico-Militares who served the province of La Union from its establishment in 1850 until thePhilippine Revolution in 1898. During this period, approximately 32 individuals alternately held the titles of Gobernador Politico-Militar and Gobernador Militar-Politico. From 1890 to 1898, these officials were ranked as Gobernador Civil or Civil Gobernador by the superior gobierno, with the honorific title"Don" prefixed to their names.
ThePhilippine Revolution began in 1896, but La Union initially saw limited revolutionary activity. On 15 November 1896, the newspaperLa Campaña de Filipinas reported that the provinces ofIlocos and La Union were"not up in arms" but showed"sympathy for the uprising." Despite this initial passivity, the province eventually joined the struggle againstSpanish colonial rule. In response, Spanish authorities enacted severe reprisals, including torture and false accusations, often targeting local elites, clergy, and suspected rebels.

In 1896, three nativecoadjutor priests from La Union,Padre Adriano Garces ofBalaoan,Padre Mariano Gaerlan ofSan Fernando, andPadre Mariano Dacanay ofBacnotan, were arrested and charged with masterminding a"supposed conspiracy" in La Union. They were brutally tortured byfriars and theGuardia Civil inVigan, enduring inhumane treatment that left lifelong scars on survivors like Padre Dacanay.
InBalaoan, a secret revolutionary group formed by seven prominent citizens namely;Luciano Resurreccion, Proceso Ostrea, Antonio Ostrea, Rufino Zambrano, Fernando Ostrea, Patricio Lopez, andJulian Peralta—sought to revolt against the tyranny of the Guardia Civil andCora Parrocos. The group was betrayed by Captain Juan ofAgoo to the friars. They were arrested, and without trial, executed by firing squad at the town cemetery. Only one of the men survived, having been wounded in the leg. In their honor, a Masonic lodge namedSiete Martires was established.[29][16]
InAgoo, around 60 suspected subversives were executed by the Guardia Civil and their bodies later interred in a corner of the town plaza. In nearbyAringay, 96 citizens were shot without trial by Spanish forces. A monument was later erected in the plaza to honor these patriots. On 10 September 1896, Spanish authorities, led byFriar Rafael Redondo, arrestedDr. Lucino Almeida, the highest-ranking native official in La Union, along with other suspected revolutionaries. They were accused of involvement in a fabricated conspiracy to assassinate Spanish officials, based on a false confession from a telegrapher. Almeida and 20 other prominent natives were exiled toBalabac Island, Palawan.
Despite these events, La Union was hailed as"una provincia modelo" (a model province) in 1897 by the pro-governmentEl Comercio for its contributions to Spain's defense. However, in 1898, the relative tranquility of La Union was shattered when an uprising and massacre inSanto Tomas ignited widespread agitation.[30]
Uprising of 1898
The revolution in La Union began on 22 May 1898, with a small uprising inSanto Tomas. A shot from a smallrevolver (“una revolver pequeña”) was heard, igniting the“seditious movement of Union.”[3] A single shot from this revolver ended the life of the much-hatedAugustinian friar,Mariano Garcia, marking the end of Spanish rule in the province. The enraged revolutionaries stormed the convent, seized the priest, chained him, and beheaded him, his head rolled to the ground like a soccer ball. This act sparked a series of mass massacres(“hecatombes”) throughout the province.[3]
The subsequent violence led to the massacre of various individuals, including Garcia's visitors and others. Women also became victims of brutal acts, with one storekeeper inSan Fernando left mentally deranged. InSan Juan, pro-Spanish inhabitants were massacred, while in Caba, pro-Spanish sympathizers were captured and heldincommunicado in the mountains. In Bauang, revolutionaries clashed with Spanish soldiers and seized the town hall, led byCaptain Remigio Patacsil.[3]
Gen. Manuel Tinio, the leader who led the Philippine revolution in La Union
From May to August 1898, citizens of La Union fought several heroic battles against the Spanish forces in key towns such as Darigayos (Luna),Bacnotan, Rabon (Rosario),San Fernando,Bangar, andBalaoan. Despite heavy losses and diminishing supplies, Spanish forces underLieutenant Colonel Jose Herreros mounted a five-day defense inCasa Real. However, they were eventually overwhelmed by revolutionaries in towns like Bangar, Bacnotan, and Balaoan, and the Spaniards were forced to surrender. The final stand in Balaoan saw Spanish forces barricaded in the convent, but despite their valiant defense, they were outmaneuvered, and many escaped toIlocos Sur.[3]
On 22 July,Novo-Ecijano troops, reinforced to over 600 men, arrived in San Fernando afterDagupan surrendered toGeneral Francisco Makabulos. The town was under siege by revolutionaries led byGeneralMauro Ortiz. Spanish forces, commanded byLieutenant Colonel Jose Garcia Herrero, fortified themselves in key buildings, awaiting reinforcements. The ensuing battle lasted for 120 hours, with the Spanish troops enduring extreme conditions.[3]Major Ceballos, who had surrendered in Dagupan, attempted to negotiate the surrender of Spanish forces in San Fernando, ultimately convincing Herreros to capitulate. The proud Spaniards with theCuerpos de Voluntaries (Corps of Volunteers) did not simply put up the white flag. This led to the signing of theActas de Capitulaciones (Acts of Surrender), and San Fernando became the 13th of 29 towns to witness Spanish surrender, with 400 soldiers and eight officers capitulating.[3][15]
After securing San Fernando, the Tinio Brigade and other revolutionaries continued north from 31 July – 18 August 1898. Key battlegrounds included the rice fields of San Juan, Bacnotan, Namacpacan, Balaoan, and Bangar. Many localKatipuneros joined the Tinio Brigade after this ordeal, which saw stubborn resistance from entrenched Spanish troops in theconvent.[3]
In theAmburayan Valley, Spanish forces built defensive trenches and placedbamboo traps. However, therevolutionaries, buoyed by previous victories, attacked with renewed vigor.[3] InSan Juan, they burned municipal buildings and the homes ofSpanish insulares, resulting in a massacre of over 100 families attempting to flee. InAgoo, pro-Spanish sympathizers were captured and executed in the mountains.[3]
As Spanish forces retreated, they reinforced their positions in Balaoan andBangar, but revolutionaries quickly fortified their own defenses. Any potential reinforcements from neighboring provinces were blocked.[3] In Darigayos Cove, Filipino rebels burned all anchored boats, preventing escape by sea. The revolutionaries then moved to Bangar, successfully besieging the Spanish forces, resulting in a decisive victory on 7 August 1898. The surrender of 87 Spaniards marked a significant milestone, with the remaining forces fleeing to Ilocos after just four days of fighting, which saw minimal Filipino casualties.[3]
By 18 August 1898, La Union had achieved final victory, marking the definitive collapse of Spanish resistance in the province. This victory brought the revolutionaries closer to their ultimate goal of freedom from Spanish colonial rule.[3]
ThePhilippine-American War in La Union began on the night of 4–5 February 1899, marked by the ringing of church bells across the province.[31] By April 1899, Filipino guerrillas, under the command ofGeneral Manuel Tinio, had prepared for combat, constructingtrenches throughout the province. Tinio's forces numbered 1,904, including 68 officers, 200bolo men"hermano", 284auxiliaries such as armorers,telegraphers, medical corpsmen,cavalry,artillerymen, and two Spanish engineers stationed in Northern Luzon.[31][32]
On 16 November 1899,President Emilio Aguinaldo arrived in La Union via theTubao trail, making his way toAringay, where he was welcomed by the townspeople (cailianes) and elites (babaknang). From Aringay, Aguinaldo continued his journey throughCava,Bauang, andNaguilian where they spent the night inconvent.[3]
On 18 November 1899, American forces underGeneral Samuel Baldwin Marks Young entered La Union, landing inRosario viaRabon Point along the coast in pursuit of Aguinaldo.[3] At dusk, American forces engaged 130 Filipino revolutionaries at Tubao, commanded by Captain Santiago Fontanilla, who led a force of four officers and 87 rifles. The Americans then moved toward Aringay, whereMajor Matthew Arlington Batson led an attack on the town the following morning.[31] He was wounded in a skirmish with Guerrilla Unit No. 5, an event known as theBattle of Aringay River.[20]
Throughout the week, heavy fighting ensued between American forces and five Filipino guerrilla units in La Union led by Colonel Juan M. Gutierrez:[33]
Guerrilla Unit 1: Operated inBangar,Namacpacan (Luna), andSudipen underCaptain Anacleto Mendoza.
Guerrilla Unit 2: Operated inBalaoan,Bacnotan, andSantol (rancheria of Balaoan) underCaptain Aniceto Angeles.
Simultaneous battles were fought across various towns, including Santo Tomas, Aringay, Naguilian, Bauang, and San Fernando. By 19 November, the Americans had taken Santo Tomas and Agoo.[31] On 20 November, General Young entered San Fernando where describe the town as“series of the most formidable entrenchments,” capturing the revolutionary headquarters and estimating the presence of 1,000 Filipino insurgents. Several revolutionaries were captured.[3]

Meanwhile, Aguinaldo continued his escape, traveling through the mountain roads of San Fernando, San Juan, and Bacnotan, narrowly evading capture. Upon reaching Balaoan, he learned of a plot to avengeGeneral Antonio Luna, who had been killed five days earlier. This plot, intended to unfold in Luna's mother’s hometown of Namacpacan (now Luna), was thwarted by Doña Laureana Luna y Novicio.[3]
On 21 November, Aguinaldo arrived in Bangar, escorted by General Tinio,[32] before continuing his journey toIlocos Sur. On the same day, La Union'sinsurrecto governor, Dr. Don Lucino Almeida y Almendrada, paid a courtesy call to General Young, offering assistance to the U.S. government. By 23 November, Young reaches Namacpacan (now Luna).[3]
Insurrecto La Union GovernorDon Lucino Almeida, who served in 1899-1901.
While seemingly cooperating with U.S. forces, Almeida secretly supported the Filipino guerrillas by establishing a network with town leaders and chieftains. He mobilized resources such as money, rice, and provisions for the guerrillas, and hishaciendas in San Juan, Balaoan, and Bacnotan served as covert guerrilla hideouts.[31][3]
From January to February 1900, the TinioBrigade engaged in several battles against American forces in La Union, achieving notable victories despite being outnumbered. In January, they repelled American forces at Malabita, San Fernando and ambushed a 40-man patrol nearBangar.
In February, they conducted additional ambushes at Sabang, Bacnotan, Panicsican, San Juan, and Kagunan in Balaoan. On 26 February, they successfully retaliated against an ambush between San Juan and Bacnotan, killing several American troops, including a captain-doctor, and capturing supplies.[3]
Filipinorevolutionary soldiers c. 1899
By April 1900,Colonel William Penn Duvall, the U.S. military governor of San Fernando, grew suspicious of Almeida's activities. First Lieutenant William Thomas Johnston was assigned to investigate Almeida's involvement in the resistance. After months of scrutiny, Almeida was court-martialed on 3 June 1900, and exiled toGuam in January 1901.[31][3]
Following Almeida's conviction, local leaders in San Fernando, Bacnotan, San Juan, Tubao, Agoo, and Rosario ceased supporting the guerrillas. Many of Almeida's former supporters switched allegiances to save themselves, earning the nickname chameleons or"balimbings." Johnston's anti-guerrilla efforts, aided by local spies, contributed to the overall pacification campaign.[31] One of them,Crispulo Patajo native from Bauang, served as a spy, scout and leader for the U.S. forces to suppress guerrilla resistance in the province.[3]
American troops c, 1899
On 17 April 1900, Patajo's forces attacked and pacified the guerrilla presence in Barrio Castro, Bangar, capturing weapons and forcing insurgents to retreat. From May to June 1900, Crispulo Patajo led successful anti-guerrilla operations throughout La Union.[3] He attacked Fontanilla's band in the Pagalan Mountains on 26 May, killing 10 insurgents and capturing 13 rifles. His forces continued to clear towns like Naguilian, Bauang, and Aringay, killing or capturing guerrillas.[3]
In San Fernando, Patajo pacified the town in one week, capturing officers and securing rifles. He also targeted northern towns like San Juan and Bacnotan, eliminating a guerrilla company and capturing 80 rifles. Despite these successes, Colonels Juan Gutierrez andJoaquin Luna managed to escape and relocated their camp further north.[3]
Between March and April 1901, guerrilla forces led by Aniceto Angeles, Sixto Hipolito, and Santiago Fontanilla engaged in skirmishes with American troops in various areas, including Sitio Guilong (Balaoan), Sitio Kalumboyan (Balaoan), Sitio Nabual (Bacnotan), and Barrio Castro (Bangar) that leads Major Aniceto Angeles withdraws.[3] While they achieved some victories, their effectiveness diminished due to internal divisions, lack of discipline, and the failure to maintain unity.[3]
By 1 May 1901, the Tinio Brigade surrendered to the Americans inSinait, Ilocos Sur, marking the end of the Philippine-American War in La Union and the surrounding region.[32][31][3]
After thePhilippine-American War, La Union, like much of the country, faced widespread chaos. La Union revolutionary leaders such as Capt. Aniceto Angeles, Francisco Peralta, and Col. Juan M. Gutierrez were executed throughpublic hanging andfiring squad inBangar andSan Fernando town plaza, underscoring the conflict’s harsh aftermath.[3][31]
From 1899 to 1901, La Union was under military rule, withColonel William Penn Duvall administering both the province andBenguet beginning on 18 March 1900. During this time, both the elites (babakanang) and townspeople (cailianes) endured forced relocations,extrajudicial killings,sexual assaults and significantproperty damage.[3] This period of military governance, however, was short-lived.
In 1901, La Union transitioned tocivilian governance, signaling the start of a more organized and democratic system inspired by American models. The transition marked a shift from the"spiritualism" enforced by the Catholic friars under Spanish rule to a secular system.[3]
Despite this shift, U.S. military leaders, including Colonel Duvall, resisted relinquishing power and frequently clashed with thePhilippine Commission, led byCivil Governor William Howard Taft. The conflict escalated to U.S. Secretary of WarElihu Root, who intervened to ensure La Union’s formal adoption of civilian governance on 15 August 1901.[3]
Joaquin J. Ortega, the first La Union Civil Governor, who served in 1901-1904
Introducing theThomasites—American teachers tasked with promoting"Americanization."English became the primary medium of instruction, aiming to instill American ideals. A notable example of this initiative’s success isCamilo Osias, a student from Balaoan, who pursued studies in the U.S. and later emerged as a respectededucator andpublic servant.[3]
By 1902, La Union's education system had grown to include 89 schools spread across variouspueblos (towns). A total of 8,917 pupils were enrolled—5,652 boys and 3,265 girls—constituting 15% of the province's population. Schools were established in key towns like San Fernando, Bangar, Rosario, Aringay, Cava, Agoo, Balaoan and Namacpacan (Luna), with some operating in repurposed Spanish-era convents.[3]
In 1902,public health boards were established to address health crises such ascholera outbreaks. Measures taken during the 1902 epidemic proved effective in curbing a severe outbreak in 1908–1909.[3] Governor Sixto Lachica Zandueta championed the establishment of a resident health officer for La Union, leading to the creation of a sub-health district by 1910. Public health continued to improve underGovernor General Francis Burton Harrison (1913–1921), with coordinated efforts significantly reducing cholera cases by 1914.[3]

American Military Post, Camp Wallace, circa 1904.
In 1902,Camp Wallace was established on Poro Islet, San Fernando, underCaptain Frank Tompkins, as it was considered a strategic location. The U.S. formally acquired it as a military reservation on 1 September 1903, and the War Department set guidelines for its creation on 13 October 1903. Governor Joaquin Ortega supported the establishment of a permanent military post in San Fernando, endorsing a petition signed by 2,637 citizens on 9 August 1902.[3][34]
The integration of non-Christian tribes from theCordilleras, referred to as the“taga-Montañosa,” became another priority. In 1902, Governor Taft proposed incorporating these groups into the municipal code or merging them withBenguet. By 1905, tensions between Bangar’s lowlanders and mountain communities led to court interventions. In 1906,Igorot settlements were transferred to sub-provinces of Benguet andAmburayan underLepanto-Bontoc province to resolve jurisdictional and tax-related disputes. By 1911, many non-Christians sought permission to resettle in lowland areas.[3]
By 1912, Christianized Igorot"Bago" communities inRosario,Tubao,San Fernando,San Juan, andBacnotan were fully integrated. Boundary adjustments and the conversion of mountain settlements intotownships followed, withPugo officially becoming a township on 11 December 1911. Despite proposals for a new province, the municipal districts of Sudipen, San Gabriel, Santol, Pugo, Bagulin, and Burgos remained part of La Union.[3] These districts served as models of harmonious Christian-Igorot relations during the colonial period. By 1920,San Gabriel, Pugo,Sudipen, andSantol became official towns underSection 2 of Act No. 2877, or theRevised Administrative Code of the Philippine Islands;Bagulin followed in 1922, andBurgos in 1925, underExecutive Order No. 54.[35][3]
UnderGovernor General William Cameron Forbes (1909–1913), infrastructure development flourished in La Union. Roads, airports, ports and railways (Ferrocarril de Manila-Dagupan) were expanded, with the rail line reachingAringay in 1910 andBauang in 1918. This enhanced connectivity significantly boosted the local economy, particularly in southern La Union, by linking it toDagupan.[3] Major projects included the construction of theTaboc Bridge on theSan Juan-Bacnotan Road, theBauang-Naguilian Road, theBacnotan-Balaoan Wagon Road, theSan FernandoWharf, and theAmburayan River irrigation system, which supported tobacco and rice fields, bolstering agriculture and trade.[3]

By 1915, under Governor Mauro Ortiz, theNaguilian Road was extended toBaguio, theSan Fernando Port became operational, theBalaoan-Bacnotan Road was initiated, and theBaroro andDarigayos Bridges were completed. By 1921, over 150 kilometers of roads had been developed, facilitating commerce and the transportation of goods.[3]
The transition to thePhilippine Commonwealth in 1935 granted La Union greater autonomy and opportunities for political engagement, though colonial structures persisted. This era fostered local development while reinforcing American influence. Full independence remained elusive until the Philippines gained sovereignty in 1946.
The American colonial period left a mixed legacy in La Union. While it brought modernization in education, infrastructure, and public health, it also entrenched colonial dependency and caused lasting cultural and social impacts. The memory of resistance and the province's enduring struggle for identity continues to shape its historical narrative and aspirations for self-determination.
As the Filipinos awaited independence under theTydings-McDuffie Act,World War II erupted, further delaying their aspirations for sovereignty.[36]
Lingayen Gulf Landings in La Union and the Japanese Advance, December 1941
TheJapanese invasion of La Union duringWorld War II was a pivotal moment in the province's history, given its strategic importance to bothAllied and Japanese forces. In 8 December 1941, Japan launched an attack on U.S. military installations including theCamp Wallace and residential areas in the province, following the attack onPearl Harbor.[37]
By 11 December, the Japanese forces had successfully capturedVigan and dispatched additional troops to seizeLaoag and its airfield. As American forces retreated,Lieutenan Gen. Masaharu Homma left a small garrison in Vigan and redirected the main forces to support operations atLingayen Gulf.
By 20 December, the combined forces of the Col. Kanno andGen. Shizuichi Tanaka Detachments advanced south along Route 3. By 21 December 1941, Japanese forces had occupiedBacnotan following the successful overcoming of Philippine defenses in the area. On 22 December, they advanced toSan Fernando further consolidating their position. Japanese troops also landed inAgoo and swiftly established control over the town by early 1942. Despite these rapid advances, Filipino and American forces continued to resist the Japanese occupation, contributing to the broader efforts of the Allied campaign in the Philippines.[38]
Battle of Rosario (Invasion of Lingayen Gulf)

On 22 December 1941, the Japanese 4th Tank Regiment and the 47th Infantry Regiment under the command of Col. Isamu Yanagi, supported by a massive flotilla of navy ships tried to land inAgoo to make it one of three major beachheads for theJapanese Invasion of Lingayen Gulf, although weather dispersed their forces and made them deploy on a wide stretch of beach that ranged fromPoro Point (San Fernando) to as far south as Damortis. These forces later met the commonwealth defence forces—consisting of the26th Cavalry Regiment (Philippine Scouts), the Philippine 21st Division, the Philippine 11th Division, and the newly formed Philippine 71st Division—in what would later be called theBattle of Rosario.[39][40]
During the Japanese occupation in the province, La Union was governed by Gov. Jorge Camacho (1941–1942), Gov. Bonifacio Tadiar (1942–1944), and Gov. Bernardo Gapuz (1945) under the administration ofPresident José P. Laurel's Japanese-sponsored"puppet" government. The province endured strict military controls, forced labor, food shortages, and widespread violence includingextrajudicial killings andsexual violence. Despite these conditions, resistance movements emerged, with many residents engaging in guerrilla warfare against Japanese forces. Guerrilla camps was established all over the province including Camp Spencer inDarigayos, Luna and Camp 121 and Barrio San Cristobal inBangar.[41]
Mangkaeng Massacre
Tomb of the Unknown Soldiers, Naguilian
InNaguilian, over 400 refugees from the barrios of Imelda, Natividad, and Ortiz sought refuge in the small, forested sitio of Mangkaeng in barrio Gusing Norte to escape Japanese forces stationed in the town proper as part ofGeneral Tomoyuki Yamashita’s rear guard during his retreat to theCordillera mountains. The area served as a strategic route for Japanese soldiers traveling between lowland and Cordillera camps particularlyBaguio.[42][43]
On the early morning of 23 January 1945, Japanese troops launched a sudden and brutal attack on Mangkaeng, aiming to eliminate potential resistance or witnesses. The unarmed villagers were caught off guard as gunfire (bayonet) erupted, killing men, women, and children. Some families attempted to flee into nearby creeks and the dense forest, hoping for cover, but the soldiers were relentless, pursuing and killing those who tried to escape. Others hid in nearby caves or bushes, clinging to the hope of survival while hearing the cries of those captured. Some survivors managed to reach neighboring villages, where they warned others of the massacre, spreading shock and grief across the province.[42]

Battle of Baroro
On 4 January 1945, Filipino-American forces captured the Baroro Bridge in Bacnotan, marking a significant turning point in the liberation of the province duringWorld War II. The bridge, a vital link connecting Northern Luzon to San Fernando, was a strategic objective for the Allied forces. The operation began with an assault by the 121st Infantry Regiment of theUnited States Armed Forces in the Philippines, Northern Luzon (USAFIP-NL), against Japanese positions along the south bank of the Baroro River.[44] The battle was characterized by heavy exchanges of gunfire, with the Filipino-American troops ultimately securing the bridge after intense fighting. This victory played a crucial role in ensuring the liberation of La Union and was followed by subsequent operations, including theBattle of San Fernando and the capture of Bacsil Ridge.[44]

Following the Battle of Baroro, Allied forces launched a concerted attack on Japanese strongholds to the south of Baroro. This included operations targeting key enemy positions along Oaig Creek, where it crossed the San Fernando–Camasin Road, as well as strategic locations such as Reservoir Hill, Insurrecto Hill, and the Bacsil–Apaleng Range. These assaults took place during the second week of February 1945 as part of the broader campaign to secure San Fernando and its surrounding areas.[45]
By 24 March 1945, after the Battle in Bacsil Ridge Allied forces had successfully secured the entire San Fernando area. This victory enabled the establishment of a critical military base "Camp Wallce" at Poro Peninsula, which became the headquarters for U.S. Army Base M. The area also served as a vital build-up zone for the projected invasion of Japan, marking a crucial step in the Allied preparations for the final stages of thePacific War.[45]

TheBattle of Bacsil Ridge ended the month-long battle for control ofSan Fernando. The Japanese defenders called the Hayashi Detachment, composed of 3,000 armed troops and 2,000 unarmed support forces, took hold of San Fernando and its surrounding areas which denied entry to the port of the town and a road leading toBaguio. As part of the San Fernando-Bacsil Operations, the 1st Battalion of 121st Infantry were sent to loosen the enemy positions starting late February with the assistance of the Allied Air Force.[47]
The 1st Battalion made a general attack to the ridge on 16 March 1945 and fought the Japanese defenders until the capture of Bacsil on 19 March. On the same day, the 3rd battalion captured the Reservoir Hill.[46] The Battle of Bacsil Ridge between the Filipino soldiers and recognized guerrillas and the Japanese Forces resulted in the recapture of San Fernando, La Union. Which resulted in the capture of San Fernando, La Union on 23 March 1945, andBacnotan, La Union and the military offensive throughout the province ended on 24 March after two months of fighting.[46][48]
Liberation of Bauang
Approach ofU.S. Naval Forces to Lingayen Gulf, January 1945 (Map)
The Liberation ofBauang, was part of the San Fernando-Bascil operations aimed to liberate the province of La Union and open one of the roads toBaguio.[49] Units fromRosario, La Union including elements of the 2nd Battalion, 121st Infantry of the United States Army Forces in the Philippines – Northern Luzon (USAFIP-NL) under the command of Major Diego Sipin, were tasked to make the northward advance toBauang.
The 2nd Battalion, 121st Infantry, USAFIP-NL reinforce the other battalions in the efforts to capture San Fernando.[49] Meanwhile, combat units from the "B" company, 1st Battalion, 121st Infantry, USAFIP-NL attacked the defensive lines in Bauang to aid the 1st Battalion, 130th Infantry (US) in its advance from the south. Bauang was first liberated on 19 March 1945, followed by the declaration of the end of operations at La Union on 24 March 1945.[49] On 4 January 1945, La Union was liberated by the Battle of San Fernando and Bacsil Ridge.[49]
As San Fernando was in ruins at the time,Bacnotan became the provisional seat of the province administration after the war. The La Union National High School was also relocated to Bacnotan as a result of this relocation. When things returned to normal, the provincial government was relocated to San Fernando, followed by the La Union National High School. The North Provincial High School was established after the provincial high school in Bacnotan was transferred (now Bacnotan National High School).
The postwar recovery period marked a return of thetobacco industry to the Ilocos Region. Ever since the end of the tobacco monopoly, tobacco production had declined in the Ilocos as Filipinos started shifting from locally made cigars to foreign made cigarettes.[50] But after reading a feature article series byMaximo Soliven which explained why Virginia tobacco would grow well on Ilocos soil, businessmanHarry Stonehill was convinced to invest extensively in rebuilding the industry. He established the Philippine Tobacco Flue-Curing and Redrying Corporation (PTFCRC) in 1951 and recruited farmers throughout Region 1 to produce tobacco.[51][52] The following year, La Union Congressman Manuel T. Cases filed a bill to "limit the importation of foreign leaf tobacco," which was eventually signed by PresidentElpidio Quirino as Republic Act No. 698.[53] This allowed Stonehill's investments to make a handsome profit,[54] and the newly-rebuilt local industry to bloom.[51] While Stonehill was later deported in the 1960s for tax evasion and bribery of government officials in what would later be called theStonehill scandal,[54] the tobacco industry continued to grow.[52][54]
The powerful family factions which had dominated La Union politics since before the American colonial era largely remained in place, although the family of CongressmanJose D. Aspiras became much more prominent after he became Marcos’ Tourism Minister. The main political change was the increased power of regional and provincial offices of national agencies, whose directors were answerable directly to Marcos.[57]
This technique used by Marcos to consolidate political power did not get much resistance in theIlocos Region,[57] including La Union, which had strong ethnic associations with theMarcos family.[58] The Marcos administration's use of violent methods for stifling dissent thus mostly took place in other, non-Ilocano provinces, such as nearbyAbra,Kalinga, andMountain Province.[58] Long-time second district congressman Manuel T. Cases had formed an alliance with Marcos[59] along with the other strongman congressmen of the Ilocos Region,[59] and his successorJose D. Aspiras was also a close associate of Marcos who was made Minister of Tourism after Martial Law was declared.
Wall of Remembrance at theBantayog ng mga Bayani including Armando Palabay
But there were still La Union natives who were willing to object to the authoritarian practices andabuses of the Marcos administration, despite personal risk.[60][61] This included San-Fernando-raised student activists Romulo andArmando Palabay, UP Students and La Union National High School alumni who were imprisoned for their protest activities, tortured at Camp Olivas in Pampanga, and later separately killed before the end of Martial Law.[62] Romulo (age 22) and Armando (age 21) were posthumously honored when their names were etched on the Wall of Remembrance at the Philippines'Bantayog ng mga Bayani, which honors the heroes and martyrs who fought the authoritarian regime.[63]
Agoo, La Union, nativeAntonio L. Mabutas had become Archbishop of Davao by the time of Martial Law, and spoke actively against the human rights abuses of that time,[64][65] particularly the torture and killings of church workers. The pastoral letter he wrote against Martial law, "Reign of Terror in the Countryside," is notable for having been the first pastoral to be written against Marcos' martial law administration,[64] and even doubly notable because Mabutas was considered a conservative within the Catholic church hierarchy in the Philippines.[66]
La Union was severely hit by the1990 Luzon earthquake. Five municipalities in La Union were affected:Agoo,Aringay,Caba,Santo Tomas, andTubao with a combined population of 132,208. Many buildings, including the Agoo Municipal hall,[67] theMuseo de Iloko, the parish church of Aringay,[68] and theBasilica Minore of our Lady of Charity,[69] collapsed or were severely damaged. 100,000 families were displaced when two coastal villages sank due toliquefaction. The province suffered many casualties leaving 32 people dead.
San Juan Surf: Surfing Capital of the Northern Philippines
From the mid-2000s to the early 2010s, an influx of entrepreneurs began putting up establishments such asboho-chic-styleart hostels andthird-wavecoffeeshops inSan Juan andAgoo.[70] They were initially attracted to the already-established surfing scene ofBarangay Urbiztondo in San Juan, but eventually envisioned business in the province as an alternative to the stresses of city-based employment.[71][72] This coincided with the phase-by-phase opening of theTarlac–Pangasinan–La Union Expressway (TPLEX), which made La Union more accessible to tourists from Metro Manila.[73]
Alongside the rising influence of social media outletsTwitter andInstagram, these factors led to a drastic tourism boom that made San Juan—previously been seen as just one of the Philippines' many surfing venues—a major backpacker's destination whose attractions centered on surfing and art.[74][75]
San Juan began to be featured prominently in independent films such as Jay Abello's 2015 filmFlotsam[76] and JP Habac's 2017 filmI'm Drunk, I Love You,[75] and the province began to be referred to by the colloquialinitialism "ElYu."[77]
Among Philippines literary circles, the town of Bauang has also become a pilgrimage site of sorts for celebrating the life of and works of writer and World War II martyrManuel Arguilla, with writers visiting the author's hometown to experience the landscapes that inspired him, and which featured prominently in his stories.[78][79] The most prominent event celebrating Arguilla was the 2017 run of the Taboan Literary Festival, a celebration of Philippine literature which changes venues every year, organized by theNational Commission on Culture and the Arts during every National Arts Month in February. Among the prominent artists who spoke about Arguilla at the festival were writer-academicButch Dalisay andNational Artist of the Philippines for literatureBienvenido Lumbera.[80]
Among the provinces in the Ilocos Region, La Union is the smallest in terms of land area, covering 149,309 hectares, which constitutes 11.60% of the region's total land area and about 0.5% of the entire country.[81] The province is divided into two districts. District I, comprising 70,069 hectares (46.93% of the province's land area), includesSan Gabriel, the largest municipality, with 15,500 hectares, followed by theCity of San Fernando with 10,688 hectares, while Luna is the smallest. District II covers 79,240 hectares (53.07% of the province), withBagulin having the largest area, followed byAringay, whileSanto Tomas occupies the least space.[82]
La Union’stopography is predominantly hilly, gradually rising eastward from itscoastal plains.[83] The province’sphysiography can be classified into four primary surface configurations: coastal plains, coastal hills, broad interior valleys, and mountain ridges with narrow valleys. These landforms have been shaped bycoral alluvium (sand and clay) deposited by flowing water.[81]
The coastal plains of La Union are narrowest near Damortis andSanto Tomas, and widest nearBalaoan, extending up to 15 kilometers inland. Along theSouth China Sea, the coastal plains transition sharply to steep ranges, with elevated areas in Santo Tomas,Agoo,Bauang, andBalaoan, and gentler slopes inBacnotan,San Fernando, andSan Juan.
These towns also featuresmangrove swamps, and the soils in this area aresandy andsaline, particularly in southern San Fernando and surrounding areas. Coastal hills in La Union rarely exceed 300 meters in elevation, merging with theCordillera mountain ranges to form narrow valleys. The soils in these areas are primarily heavyloam andclay, which are common in Agoo, Aringay, Santo Tomas, andRosario, while northern San Fernando is characterized by gravelly,eroded loam.[83]

The eastern frontier of the province is predominantly mountainous, dominated by the Gran Cordillera mountain ranges, specifically the Central and Northern Cordillera, which run parallel to the South China Sea coast. The highest peak in the province is located inBagulin, at an elevation of 1,200 feet, with other elevated areas found in San Gabriel andBurgos. The fertile, fan-shaped interior valleys in San Juan, San Fernando, and Balaoan, formed byriver delta sediments, are crucial for agriculture, though they are prone toflooding during heavy rainfall.[3][81]
Salty-loam andalluvial soils, which are ideal for crops such as rice and tobacco, are prevalent inNaguilian,Aringay, Bauang, Balaoan, andLuna. The eastern mountain ranges, characterized bysteep slopes and narrow valleys, are covered with reddish, clayish soils, particularly in Bacnotan, Agoo, San Fernando, San Juan, and Bauang, which are not suitable for agricultural use.[81]
La Union is home to ninevalleys—four in the northern part of the province (Bangar, Balaoan, Bacnotan, San Juan) and five in the south (Tubao, Aringay, Santo Tomas, Rosario, Naguilian)—which support agricultural land. These valleys are crossed by narrow, turbulent rivers. Further to the east, elevated plateaus and peaks that rise dramatically.[3][81]
Amburayan River: The largest river in the province, it passes throughSan Gabriel,Sudipen, andBangar, marking the northern boundary betweenIlocos Sur and La Union before flowing into the South China Sea.
Bued River: Flows throughPugo and Rosario, draining into the Lingayen Gulf, marking the southern boundary withPangasinan.
Aringay River: Class B River Basin with a length of 45 km that originates inBenguet, passes through Pugo, Tubao, and Aringay, and flows into both the South China Sea and Lingayen Gulf.[84]
Baroro River: A length of 22.2 km that starts in the mountains of San Gabriel, crossing San Gabriel, San Juan, and Bacnotan, and flows into the South China Sea.[85]
Maluyo River (also known as Bucilac River): Flows through Santol, Balaoan, and Bangar, marking regional boundaries.
Maragayap River: Passes through San Gabriel, Balaoan, and Bacnotan, eventually flowing into the South China Sea.
Darigayos River: Flows from the mountains behind Balaoan to Darigayos Cove, emptying into the South China Sea.

Coastal area in Santo Tomas
La Union’s coastal rim is indented by four bays or coves: San Fernando (at the central point), San Juan in the northeast, Darigayos in the northwest, and Santo Tomas in the southwest.[3]
Land use in La Union is varied. Forests and wooded areas cover 41,240 hectares (27.62%), enhancing its biodiversity. Agriculture dominates, occupying 54,701 hectares (36.64%), while grasslands and shrublands account for 22,834 hectares (15.29%). Urban development takes up 15,555 hectares (10.42%), alongside 14,788 hectares (3.30%) of bare land, and 191 hectares (0.13%) are classified as wetlands.[81]
La Union is also affected bytropical cyclones, with 85 such weather systems recorded between 1948 and 2009, including one super typhoon. These storms, which occur most frequently from July to October, have adverse effects on tourism, agriculture, and infrastructure. During strong typhoons, businesses often close, power outages are common, transportation becomes limited, and crops suffer damage, reducing agricultural production.[1][86]
La Union consists of576barangays, which are spread across its19municipalities and1city. According to the 2020 census, the barangay with the highest population isSevilla, located in theCity of San Fernando, boasting a population of 11,316. When cities are not taken into account, Central East (Poblacion) in the municipality ofBauang ranks as the most populous barangay, with 4,249 residents. In contrast,Caggao inBangar has the smallest population, totaling just 192 inhabitants.[90]
According to the 2020 census conducted by thePhilippine Census of Population and Housing, La Union had a population of 822,352, with a population density of 550 people per square kilometer (1,400 per square mile).[2] This is an increase of 35,699 persons over the total population of 786,653 persons in 2015 Census of Population.[91] The household population was nearly evenly distributed, with 50.6% male (414,860) and 49.4% female (405,480).[92]
San Fernando is the most populous area in La Union, with 125,640 residents (15.28% of the province's total population), followed byBauang (78,449),Agoo (66,028),Rosario (60,278), andNaguilian (52,189). Conversely,Burgos is the least populous municipality with 9,006 residents, followed bySantol (14,166),Bagulin (14,428),Sudipen (17,187), andSan Gabriel (18,943).[91]
Santol recorded the fastest population growth between 2015 and 2020, with an annual rate of 2.71%, followed by Burgos (2.34%),Tubao (2.13%),San Juan (1.81%), and Rosario (1.77%). In terms of population density, Agoo was the most densely populated municipality, with 1,250 persons per square kilometer, while Burgos had the lowest density at 127 persons per square kilometer.[91]
Age distribution reveals that 26.3% of the population were young dependents (under 15 years), 66.1% were ofworking age (15–64 years), and 7.6% were elderly (65 years and older). Males slightly outnumbered females in younger age groups, while females were more numerous among the elderly, reflecting higherlife expectancy for women. The overallsex ratio was 102 males per 100 females, with variations across age groups: 108 males per 100 females among those under 15, 105 in the working-age population, and 70 among the elderly.[94][86]
The median age in La Union was 28.5 years.Senior citizens (60 years and older) comprised 11.5% of the population, 56.4% of whom were women. As of 2012, La Union had the longest life expectancy in the Philippines at 78.3 years.[95]
According to the 2020 census onreligious affiliation in theIlocos Region, the majority of La Union's household population identifies asChristian, withRoman Catholics comprising 69.5% (695,867 individuals).Iglesia ni Cristo represents a significant minority with 23,374 members, whileIslam accounts for 0.19% of the population (1,932 adherents).Buddhism, though present in smaller numbers, constitutes 0.25% or 163 of the population.[96]
Historically, La Union has been home to several ethnolinguistic groups, including theIlocanos,Pangasinan, andCordillerans (Igorot). The Cordillerans primarily consist of theIbaloi,Kankanaey, and the Bago, also known as Bago-Igorot. The Bago are a highland indigenous people referred to as new Christian converts during Spanish colonization in the province.[3][97]
Ethnically, La Union is predominantly Ilocano, according to a 2020 report by thePhilippine Statistics Authority. TheIlocano ethnic group accounts for 673,312 or 81.88% of the population.[99] In the southwestern part of the province, there are 10,319Pangasinan people. Indigenous communities, including theKankanaey (42,552), Bago (24,757), andIbaloi (9,107), reside in the municipalities ofSudipen, Santol, San Gabriel, Bacnotan, Tubao, Pugo, Bagulin, and Burgos.
InBagulin alone, 85% of the population, or 11,539 individuals, belong to indigenous groups.[100] InPugo, the majority of indigenous residents are from the Bago people.[97] These communities have faced displacement, such as the eviction from the Mount Shontoug area in Pugo during the construction of the Marcos bust.[101][102][103] Southern La Union, particularly Agoo, Santo Tomas, and Rosario, was historically ethnically Pangasinan;[5] by the 16th century, migration from northern La Union and Ilocos, as recorded by Fray Andrés Carro in 1792, resulted in the area becoming predominantly Ilocano-inhabited and ethnically Ilocanized Pangasinenses.[104][3]
Iloco, or Iloko, is the primary language spoken in La Union, with the Abagatan (Southern) dialect as its regional variation. In 2012, Iloco was officially recognized as the language of La Union throughProvincial Ordinance No. 026-2012, known as the Iloco Code.[107]Pangasinan is also spoken in the southern part of the province, particularly near the border withPangasinan. Meanwhile,Kankanaey andIbaloi are spoken by theCordilleran communities residing in the highland areas of La Union.
Historically, in 1884, Governor Federico Francia issued anespediente (report) on thedialectos que hablan (dialects spoken) in La Union.[3] The report noted that mostumilis (townspeople) spoke Ilocano and Pangasinan, withSanto Tomas andRosario being the only towns where both languages were spoken due to their proximity to Pangasinan. The remaining 11 towns predominantly spoke Iloco, excluding the scatteredIgorrotes communities inrancherías. Up to the end of Hispanic rule, Ilocano remained the predominantlingua franca of La Union.[3]

La Union’s economy is driven by three primary sectors:agriculture,industry, andservices. The service sector plays a dominant role, comprising 81.28% of all business establishments, while industry contributes 17.21% and agriculture makes up 1.51%. In 2022, La Union emerged as the second fastest-growing economy in theIlocos Region, with a growth rate of 7.7%.[116]
