La Rioja (Spanish pronunciation:[laˈrjoxa]), officiallyProvince of La Rioja is aprovince of Argentina located in the west of the country. The landscape of the province consists of a series of arid to semi-arid mountain ranges and agricultural valleys in between. It is in one of these valleys that the capital of the province, the city ofLa Rioja, lies. Neighboring provinces are, from the north clockwise,Catamarca,Córdoba,San Luis andSan Juan. The Triassic sauropodomorph dinosaurRiojasaurus is named after the province.
Petroglyphs created by early indigenous peoples at theTalampaya National Park are dated around 10,000 yearsBC. Succeeding cultures of indigenous peoples developed here. TheDiaguita,Capayan and the Olongasta peoples inhabited the territory of present-day La Rioja Province at the time of encounter with theSpanish colonists in the 16th century.
Juan Ramírez de Velazco foundedTodos Los Santos de la Nueva Rioja in 1591 under the government ofTucumán of theViceroyalty of Peru. In 1630 theCalchaquí people revolted against the Spanish, but the governor Albornoz suppressed them.
In 1783, after the creation of theViceroyalty of the Río de la Plata, the control of the province of 10,000 inhabitants passed to theCórdoba independency. The province acquired independence from Córdoba in 1820. Following attempts byBernardino Rivadavia, the first elected President of Argentina, to impose a centralist constitution, thecaudilloJuan Facundo Quiroga emerged as a popular leader. He represented their preference for more autonomy, for which they continued to press following Quiroga's 1835 assassination. After a period of internal instability in Argentina, the province finally joined theArgentine Confederation in 1853.
Carlos Saúl Menem was the only Argentine president of Arab descent and raised as a Muslim
La Rioja attracted fewer immigrants from Europe than did other Argentine provinces from 1890 to the 1930s.
SomeSyrian andLebanese immigrants did settle in the province, among whom the most well-known is probably the Menem family. Coming from what had been theOttoman Empire, Saul Menem and his wife were of Armenian and Alawi ancestry. He prospered as a traveling salesman and sent his eldest son,Carlos Menem, to Spain for college. The younger Menem was elected governor of La Rioja Province in March 1973, was imprisoned during the subsequentdictatorship and was elected president of Argentina in 1989, serving until 1999. During those years, he steered billions in federal public works spending into La Rioja. Although the province remains less developed than the average in the nation, its economy today compares favorably with those of its neighbors.
Located in theArgentine Northwest area, its landscape is arid to semi-arid, and the dry climate receives annually 200 mm of precipitation, has short winters, and very hot summers.
From theAndes at the west, with peaks of up to 6,795 meters (Monte Pissis), the relief's height descends towards the sierras of the neighbouring dryPampas zone. Most ranges in La Rioja are oriented north-south. The province's two largest cities,La Rioja andChilecito are separated bySierra de Velasco and west of Chilecito and Famatina rises theSierra de Famatina with heights of up to 6,250 m.a.sl. (≈20500 feet).
TheTalampaya National Park is a dry red-soil canyon of the dry Talampaya river, which contains many cliff walls and rock formations that make it an interesting tourist destination.
La Rioja's economy, estimated at US$1.822 billion in 2006, is the second-smallest among Argentina's provinces.[4] Its per capita output of US$6,283, though about 30% below the national average, makes it the most well-developed in northern Argentina.[4]
Its economy is, likewise, very well-diversified. Agriculture (long limited by La Rioja's dry, mountainous terrain) adds less than 5% to its output. La Rioja's agriculture (as well as cities) lies on the banks of the few permanent rivers and oases that allowirrigation, with only 190 square kilometres of cultivated land.Vineyards,nuts andolive plantations are the most common, followed by cotton.
The province's main crop is the grape, and its associated wine production, especially around theChilecito area, with a production of 8 million litres per year.
Cattle (250,000 head) and goats (150,000 head) are secondary activities, particularly for skin and leather.Clay represents the main mining activity, anduranium is also extracted nearEl Colorado.
Manufacturing in La Rioja has expanded considerably since Gov. Menem began attracting investment into the province, after 1983. Limited mostly to light industry like bottling and food processing, it, nevertheless, adds about 20% to La Rioja's output. Tourism is, likewise, an expanding activity. Besides theTalampaya National Park, tourists visiting La Rioja usually go also to the Chilecito town,Cerro de La Cruz,Termas de Santa Teresita hot springs and the village ofVilla Sanagasta.
Since 2024 it has its own currency,[5] the chacho, which was introduced in response to the economic problems caused by PresidentJavier Milei's austerity program and accompanying cuts to federal budget transfers.[6]
The provincial government is divided into the usual three branches: the executive, headed by a popularly elected governor, who appoint the cabinet; the legislative; and the judiciary, headed by the Supreme Court.
The Constitution of La Rioja Province, Argentina forms the formal law of the province.
In Argentina, the most important law enforcement organization is theArgentine Federal Police but the additional work is carried out by the La Rioja Provincial Police.
The province is divided in 18departments (Spanishdepartamentos). They are formally considered to be a single municipality, and usually contain one or more population centers (i.e. towns and cities).
