The history ofChinese Americans in theUS state ofIdaho spans its history as both a territory and state. It began in the 1850s with the arrival of a group of miners fromCalifornia. During the 1860s, a large number of Chinese immigrants, primarily working in the mining industry, arrived in theIdaho Territory, and according to the1870 United States census, there were 4,274 Chinese people out of a total population of 14,999. In severalmining communities, Chinese immigrants constituted a majority of the population. These immigrants faced discrimination from the majority white American population, which included legislation that targeted them for taxation and prohibited their involvement in certain industries, among other things. By the 1880s, there had been numerous incidents of violence against the Chinese, including multiple group killings and the expulsion of Chinese communities from several municipalities. Over the course of the 19th century, the population experienced sustained decline, reaching 859 by 1910 and further dropping to 208 by 1940. However, by the 2010s, the population had increased, due in large part to a growth in the Chinese American community in theTreasure Valley area. By 2018, there were approximately 5,000 Chinese Americans in Idaho, with a totalAsian American population of roughly 25,000.

Humans first arrived in the area of modern-dayIdaho approximately 11,000 yearsBefore Present.^[1] By the beginning of the 19th century, there were several groups ofindigenous peoples of the Americas living permanently in the region, with others living in the area on anomadic basis.^[1] The firstwhite people arrived in the area in the early 19th century, with members of theLewis and Clark Expedition reaching the area in 1805.^[1] Permanentwhite American settlement began around 1810 as part of theNorth American fur trade.^[2] In addition to the fur trade, some subsequent settlement efforts stemmed fromChristian mission efforts toconvert theNative Americans in the area.^[2] In 1863, theIdaho Territory was organized as aterritory of the United States.^[3] Idaho became aU.S. state in 1890.^[4]

In 1856, a small group ofChinese miners fromFresno, California, traveled north into the Rocky Mountains, reaching thedrainage basin of theBoise River in modern-day southern Idaho.^[5] In 1859, another mining group visited the basin.^[6] In 1860, gold was discovered in modern-dayPierce, Idaho,^[7][8][9] with additional discoveries made around the same time in other parts of the region, includingIdaho City andWarren.^[10] This prompted an influx of several thousandminers into the region,^[7] including both white people and Chinese immigrants.^[11] In 1862, when gold was discovered in the watershed of the Boise River, Chinese people were among the first to begin mining in the area.^[12] That same year, a Chinese person was recorded for the first time in the area aroundLewiston.^[7] While Chinese people initially settled in the northern part of the territory, by 1865, several had settled the southern part as well, including theOwyhee Mountains region.^[13]

The Chinese immigration to Idaho was part of a larger trend of Chinese immigration to thePacific Northwest that occurred during the 1860s.^[14] Per historian Carlos A. Schwantes, reasons for the increase in emigration from China during this time includedfamines,overpopulation, and the impact of theTaiping Rebellion, which lasted from 1850 to 1864.^[14] Among allAsian American groups living in the region during this time, Chinese Americans were the most populous.^[14] The largest job sectors for Chinese immigrants during this time included mining andrailroad construction.^[14] Concerning the former, the Chinese workers often mined in areas that had already been mined by white workers,^[12] working in large teams to extract resources that had been passed over in previous mining efforts.^[7] By 1870, over half of the miners in Idaho were Chinese.^[15][16][6] Chinese mining communities emerged that included the establishment of medical facilities and gardens to aid the miners.^[7] According to Idahoan historian Arthur Hart, some of the Chinese immigrants in Idaho had previously been farmers in thePearl River Delta who continued to practice agriculture in the United States.^[11] Concerning the railroad industry, Chinese laborers in Idaho worked on the construction of theNorthern Pacific Railway.^[17] Other common jobs during this time included the operation oflaundries, restaurants, and shops.^[17]

In the1870 United States census, Idaho was shown to have a population of 14,999, of which 4,274 were Chinese.^{[18][6][note 1]} As a percentage of the population, Chinese people represented approximately 28 percent, with white people accounting for about 71 percent.^{[19][note 2]} This Chinese population was largely male, as very few women immigrated to the United States during this time,^[20] with the 1870 census recording only 129 Chinese women in the territory.^[9] Initially, Chinese immigrants were restricted to living inChinatowns throughout the state,^[20] such as inBoise,Lewiston, andSalmon.^[9] Boise'sChinatown was centered in the city'sDowntown area,^[21] while another local area of Chinese settlement was centered in present-dayGarden City.^[22] By the 1870s, Lewiston's Chinatown, located near the confluence of theClearwater River andSnake River,^[7] had a population of about 1,500 Chinese people.^[7] Severalmining communities, includingCenterville, Idaho City,Pioneerville, andPlacerville, had Chinese-majority populations.^[18] In 1879, Warren had a Chinese population of about 800, compared to a white population of about 200.^[23] Chinese communities often operated their owncemeteries and made arrangements for the eventualexhumation of corpses back to China.^[7] InSilver City, which had a Chinese population of about 700 in 1874, the community operated several laundries, restaurants, and stores, as well as aMasonic lodge, two temples, and fivegambling houses.^[14]

During the 19th century, Chinese immigrants in Idaho, as in other parts of the country, were subject to anti-Chinese sentiment by white Americans.^[7] Chinese immigrants were barred fromnaturalizing and gainingAmerican citizenship, and there were restrictions on purchasing land.^[19] Violence against Chinese people was also common in Idaho, with Hart stating in 2020 that murder victims in Idaho during the 1860s "were often Chinese".^[24] Reflecting the anti-Chinese sentiment that was common at the time, journalistJames O'Meara, as the editor of theIdaho World newspaper in Idaho City, wrote in 1865, "TheChinamen are coming. Lord deliver us from thelocusts of Egypt, they devour all men before them."^[14] Similarly, an 1868 article in theIdaho Tri-Weekly Statesman stated, "The influx of Chinamen continues unabated to the great disgust of the American miners generally".^[9] Anti-Chinese sentiment was further reflected in the common names given to local plants and geographic features. For instance,Lactuca serriola was commonly called "Chinese lettuce",^[25] while a mountain nearPocatello was called "Chink's Peak".^{[26][note 3]} In 1891, acity directory of Boise listed the "Anti-Chinese Hotel" as a hotel in operation at the time.^[27]

Initially, Chinese residents of the territory were barred from owning mining claims.^[9] However, by 1865, many of these claims had been exhausted of the easily accessible gold, and white claim-owners began selling or leasing them to Chinese miners to fund mining activity elsewhere.^[9] For instance, Chinese miners were initially not allowed in Warren after gold was discovered there in 1862.^[23] However, after many of the claims in the area had been mined for several years, the community voted to allow Chinese miners into the area in 1869.^[23] In 1867, the territorial government of Idaho passed ananti-miscegenation law barring white people from marrying, among other groups, "Mongolians".^[28] In 1906, after gaining statehood, Idaho enacted an anti-miscegenation law specifically prohibiting marriage between Chinese and white people.^[29] This law would be in force until 1967, when theSupreme Court of the United States ruled that anti-miscegenation laws were unconstitutional.^[20]

In 1864,^{[note 4]} the Idaho government passed a Foreign Miners' Tax, also known as the "China Tax", which specifically targeted Chinese miners in the territory.^[12] The law had been proposed byIdaho House of Representatives member William Goulder, a miner fromShoshone County,^[7] and was modeled after similar taxes that targeted Chinese individuals that had been passed in other states and territories of theWestern United States, such asCalifornia (1852)^[12] and theWashington Territory (1864).^[14] Per the Idaho law, each Chinese miner would have had to pay several dollars to the territorial government.^{[note 5]} The law additionally classified all Chinese individuals in the territory as miners and allowed for localsheriffs to seize and auction property if the tax were not paid.^[14] The Chinese community in Idaho opposed the law and challenged its constitutionality in court, though ultimately failed in having it voided.^[30] However, many refused to pay, and per historiansJohn Mack Faragher andRobert V. Hine, there is no evidence that any Chinese person was prosecuted fortax evasion.^[31] Ultimately, the "China Tax" was declared void by theEnforcement Act of 1870.^{[note 6]}

In 1882, the federal government of the United States enacted theChinese Exclusion Act.^[17] The act barred Chinese immigration to the United States until 1892 and placed further restrictions on Chinese individuals already in the country, barring them from working in certain industries (such as mining) and preventing them from gaining citizenship.^[32] Anti-Chinese legislation during this time further diminished the ability of Chinese individuals who had returned to China from reentering the United States or from bringing their spouses with them.^[7] This anti-Chinese legislation was supported by whitelabor unions,^[19][32] such as the regionalKnights of Labor.^[33] By the time the Exclusion Act had passed, the Chinese population in Idaho had already decreased by about 1,000 compared to its peak.^[7] The Chinese Exclusion Act was subsequently renewed in 1892 and later in 1902.^[27] When Idaho became a state in 1890, its constitution specifically barred "Chinese or persons of Mongolian descent, not born in the United States" from holding elected offices, participating injuries, or from voting.^[34] That same year, the state passed aconstitutional amendment barring noncitizens from employment inpublic works projects, which specifically targeted Asian people.^[35] At the time, the Chinese population was over 2,000.^[36]

In the 1880s, there were several instances when Chinese people were violently expelled from locales.^[33][27] For instance, in the Washington Territory, the Knights of Labor led expulsions in severalcoal towns in theCascade Range and inTacoma, where the Chinese community numbered about 700, or one-tenth of the city's total population.^[33] Additional incidents of anti-Chinese violence occurred in Idaho during this time.^[32] In 1883, a conflagration affected Lewiston's Chinatown, with firefighters only intervening when the fire threatened buildings outside of that community.^[7] In an 1884 editorial in theCoeur d'Alene Sun, the newspaper stated that any Chinese miner who wished to come to theIdaho panhandle should prepare for a funeral, insinuating their death.^[32] Per Schwantes, Idaho during the mid-1880s experienced numerous instances of anti-Chinese violence, with no individuals punished for the acts.^[32] This included an incident in Pierce where five Chinese individualswere lynched by vigilantes who believed that they had murdered a white businessman.^[32] This occurred in September 1885.^[37] In December 1885, theIdaho Statesman newspaper published an article that spoke favorably of a then-ongoing effort in Boise to not hire Chinese people and to boycott businesses that did.^[11]

Around that time, a large anti-Chinese convention was taking place in Boise, which coincided with an increase in anti-Chinese violence in the territory.^[17] A similar convention was held in February 1886 inWeiser that included a call to action "to rid our yet unsullied community of the few lecherous, uncivilized heathens who now infest it, and to prevent their further encroachment upon us".^[37] In June 1886, someone detonated an explosive underneath a Chinese laundry in Broadford, which destroyed the building and injured an employee.^[37] Around the same time, a white mob attacked the Chinese community inClark Fork by throwing bombs at the structures.^[37] In September 1886, both theIdaho Democratic Party and theIdaho Republican Party adopted anti-Chinese planks into theirplatform.^[37] In May 1887,^[37] over thirty Chinese individualswere massacred inHells Canyon,^[38] near the Idaho border in Oregon.^[39] These individuals had been traveling upriver from Lewiston at the time of their killing.^[7] That same month, a week-long riot occurred in Salmon that saw white people attack the Chinese community there.^[37]

In 1891, white residents of Clark Fork forcibly expelled the city's Chinese population.^[40][9] A similar expulsion occurred the following year inBonners Ferry.^[40][9] During the 1890s, the Chinese population in the region declined, coinciding with an increase in the Japanese population,^[32] with both groups facing anti-Asian discrimination and violence.^[41][42] In 1892, Japanese railway workers were expelled fromCaldwell,Mountain Home, andNampa.^[43] In Caldwell and Nampa, some Chinese individuals were forcibly expelled alongside the Japanese workers.^[41] In 1909, the Chinese population ofMoscow was expelled from the city.^{[9][40][note 7]} According to a 2021 article published byKUNC, following this expulsion, Moscow was likely asundown town.^[36] In 1983, a resident of Moscow who was a child during the expulsion said that she had received some of the possessions of the expelled, including several dishes.^[36] Chinese Americans would not live in Moscow again until about 20 years later.^[36] Prohibitions against Chinese residency also existed inTwin Falls andWallace.^[9]

According to historian Liping Zhu, between 1863 and 1900, 25 Chinese people were killed in anti-Chinese riots in Idaho.^[44] Furthermore, these riots resulted in the displacement of 528 Chinese people.^[44] Per Zhu, the riots primarily took place in central and northern Idaho, and none are recorded as having happened in the Boise River basin.^[44]

By 1910, the Chinese population in the state had decreased to 859.^[17][9] By this time, a majority of the Chinese immigrants who had come to Idaho in the 19th century had returned to China.^[48] By 1920, the state's Chinese population constituted about 0.5 percent of the total population, which was nearly 99 percent white.^[19] By 1940, there were only 208 Chinese people in the state.^[22] In the 1960s and 1970s,^[11]urban renewal in Boise resulted in the demolishment of much of the city's Chinatown.^[22] This included a brick building that had been built in the early 1900s for theHip Sing Association, which was demolished in 1971.^[49] In 1989, archaeological excavations were undertaken on a Chinese mining area along in theSnake River Canyon near Twin Falls.^[50] Around 1990, a historical marker was erected near the site of the 1885 Pierce City lynching.^[51]

The 2010s saw a growth in Idaho's Asian American population, and by 2018, there were roughly 5,000 Chinese Americans living in the state, with a total Asian American population of about 25,000.^[22] Of the Chinese Americans in Idaho, about half lived in theTreasure Valley region.^[22] Per theIdaho Statesman, the Chinese American growth in the region could be partially attributed to the increase in job opportunities from employers such asBoise State University,Hewlett-Packard, andMicron Technology.^[11] In 2018, theStatesman published an article discussing plans for the creation of anAsian supermarket in Boise.^[22] By 2020, the Boise Chinese Association, which was formed to celebrate Chinese culture in the area, had over 400 members.^[11]

In 2010, the Idaho Chinese Organization was founded in order to bring attention to Chinese culture and history in the state.^[22] In February 2016, the organization organized a march of over 100 people in Boise in support ofPeter Liang, an officer in theNew York City Police Department who had recently been convicted ofmanslaughter in thekilling of Akai Gurley, anunarmed African American.^[52] The march went from theIdaho Black History Museum to theIdaho State Capitol, where a rally took place that included the participation of State RepresentativeSue Chew.^[53] On August 10, 2021, the Idaho Chinese Organization organized a "Polly Bemis Day" celebration at the Idaho State Capitol to celebrate Polly Bemis, a Chinese pioneer of Idaho.^[54] The celebration included the unveiling of a state of Bemis on the steps of the capitol, with plans for the sculpture to later be permanently installed near the Polly Bemis House.^[55] The event was attended by about 100 people and included the participation of several prominent members of the state's Asian American community, including State Representative Chew and Boisechief of police Ryan Lee.^[56]

Beginning in 2008, an annual conference called "Chinese Remembering" has been held in Lewiston to discuss Chinese history in the area.^[7] In reporting on the 2009 conference, Jennifer K. Bauer of theAssociated Press said that Chinese history in the state was "not well known" at the time, but that awareness was increasing in the region.^[7] The conferences also served as memorials for the 1887 massacre in Hells Canyon, which occurred near Lewiston.^[57][58] During the 2012 conference, a granite memorial was installed at the site of the killings.^[59][60] The memorial was created by a company in Lewiston and contained a brief description of the massacre in three languages:Chinese,English, andNez Perce.^[61]

In 2014, historian Priscilla Wegars noted that the state had taken some steps in recognizing its Chinese residents, noting the restoration and preservation of several historic houses and shops owned by Chinese residents.^[9] In July 2018,Idaho Public Television aired an episode of itsIdaho Experience program dedicated to the history of Chinese immigrants in the state, titled "Forgotten Neighbors: Idaho's Chinese Immigrants".^[48] Concerning the episode, series producer Melissa Davlin said, "Not many Idahoans know the history of Chinese workers in our state. This episode doesn't just tell their stories. It also explores what it means to be an Idahoan and who gets to define what 'Idahoan' means."^[48] In 2022,Boise State Public Radio reported that there was a growing push to recognize the state's Chinese American history.^[62] That same year, the Idaho Museum of Mining and Geology in Boise announced the celebration of an exhibit dedicated to the history of Chinese miners in the state.^[10] In the 2020s, authorJenny Tinghui Zhang published her debut novel,Four Treasures of the Sky, which dealt with Chinese history in Idaho during the late 19th century.^[63] Zhang discussed the historical context of her book with a state historian in an interview with Boise State Public Radio.^[63]

In 2014, Wegars noted that there were several sites of historic significances to the Chinese American community in Idaho, which included the Pon Yam House in Idaho City and thePolly Bemis House near theSalmon River.^[9][64] The former was a preserved store operated by a Chinese businessman during the late 19th century.^[9][64] The latter, located about 44 miles (71 kilometers) east of Riggins, was the residence of Chinese pioneer Polly Bemis.^[54] As of at least 2021, the site is on theNational Register of Historic Places (NRHP).^[54] Another NRHP property associated with the Chinese history of the state is a terraced garden in thePayette National Forest.^[65] Additionally, a memorial exists in Glenns Ferry that honors the contributions of the state's Chinese American community.^[66] In 2020, it was rededicated.^[66] In the late 19th century, many Chinese immigrants began to farm the area that is now Garden City in theBoise metropolitan area.^[67] Due to this, a major thoroughfare in the city is called "Chinden Boulevard", as a contraction of "Chinese garden".^[67][68]

In Boise, there is anurban legend that Chinese residents in the late 19th century created a tunnel system underneath the city, similar to theShanghai tunnels inPortland, Oregon.^[69] Per the legend, the tunnels were located around Boise's Chinatown, centered around the present site ofThe Egyptian Theatre, and were used to travel betweenopium dens.^[21] However, there is no evidence for the existence of these alleged tunnels.^[21][69] Fictional accounts of the tunnels have been reported in several Boise publications, such as in a 1981Halloween story in theIdaho Statesman and in a 2002April Fools' Day story in theBoise Weekly.^[21] In 2017, theIdaho State Historical Society uncovered a video recording of a journalist interviewing individuals about the tunnels.^[49]
