Tucumán Province
Densely populated agricultural province; site of Argentina's 1816 independence declaration.
Tucumán Province, located in northwestern Argentina, is the most densely populated and second-smallest of the country’s provinces by land area. Its capital is San Miguel de Tucumán, often shortened to Tucumán. The province is nicknamed *El Jardín de la República* (The Garden of the Republic) due to its highly productive agricultural output. Before Spanish colonization, the region was inhabited by the Diaguita and Tonocote peoples and lay at the outer limits of the Inca Empire. The word “Tucumán” likely originates from Quechua languages, possibly derived from *Yucumán* (“place of origin of several rivers”) or *Tucma* (“the end of things”). The first Spanish settlement, Barco, was established on the Dulce River in 1549 by Juan Núñez de Prado, who named the province after a local leader, Tucumamahao. After a rebellion forced relocation, San Miguel de Tucumán was founded in 1565 and later moved in 1685 due to frequent indigenous attacks. During the colonial era, Tucumán served as a midpoint for gold and silver shipments from the Viceroyalty of Peru to Buenos Aires, supplying cattle, textiles, and wood products. The creation of the Viceroyalty of the Río de la Plata in 1776 ended these convoys, and British imports further harmed the local economy. On July 9, 1816, the Congress of Tucumán declared the independence of the United Provinces of the Río de la Plata from Spain. In 1820, Governor Bernabé Aráoz proclaimed a short-lived Federal Republic of Tucumán, which collapsed when neighboring provinces withdrew. The early 20th century brought prosperity through sugarcane production, railways, and landmarks like Ninth of July Park and the Tucumán Government Palace. However, a sugar price crisis and President Juan Carlos Onganía’s 1966 closure of eleven large state-owned mills triggered economic hardship and instability. In 1975, President Isabel Perón declared a state of emergency, leading to Operation Independence, a military campaign that targeted both the ERP and local officials, lawmakers, and faculty. General Antonio Domingo Bussi, the operation’s commander, became governor under the 1976 dictatorship, overseeing public works but also presiding over severe human rights abuses. He was later elected governor in 1995. Since 2002, the province’s economy has recovered strongly, with Governor José Alperovich (elected 2003) presiding over record public works investment.

Lore & Background
The United Provinces of the Río de la Plata declared independence on July 9, 1816, at the Congress of Tucumán. The declaration used the name "United Provinces in South America" (Spanish: Provincias Unidas en Sud-América), probably chosen because it was a more encompassing name, and the borders of the new state were not clear yet. The state that succeeded the Viceroyalty of the Río de la Plata in 1810 used different names depending on political interests and common usage. The name "United Provinces of the Río de la Plata" was officially adopted by the First Triumvirate on 22 November 1811, in the 1811 Provisional Statute. It became the most common name during the War of Independence and is recognised as an alternative name of the state according to Article 35 of the Constitution of Argentina, although it is not used in practice. The name "Argentina" gained popularity during the 1820s thanks to the drafting and approval of the 1826 constitution, although United Provinces of the Río de la Plata continued to be the most common name for the State. After the 1831 Federal Pact, the name Argentina as part of Argentine Confederation began to be widely spread. The name "Argentine Republic" (Spanish: República Argentina) was officially adopted by the 1826 constitution. However, in 1827, the constitution stopped being applied. Nowadays, it is the most common official name used by Argentina.
