Jujuy is a province of Argentina, located in the extreme northwest of the country, at the borders with Chile and Bolivia. The only neighboring Argentine province is Salta to the east and south.
Pre-Columbian inhabitants, that would later mix with the Incas during their expansion period, practiced agriculture and domesticated the guanaco. They had huts made of mud, and erected stone fortresses to protect their villages. An example of such fortresses is Pucará de Tilcara, Pucará meaning "Fortress" (word also used for the Argentine combat aircraft Pucara).
In 1593 a small settlement is erected in the Jujuy valley by the effort of Francisco de Asgaranaz y Murguía. In spite of the attacks of the calchaquíes and omaguacas aborigines, the population and activity of the village consolidated and grew.
At the end of the 17th century, the customs to the Viceroyalty of Peru is transferred from Córdoba to Jujuy.
With the separation from Peru and the creation of the Viceroyalty of the Río de la Plata, Jujuy losses its importance and its population starts diminishing.
During the May Revolution and the battles for the independence of the United provinces of the South, many confrontations took place in Jujuy because the Spanish forces concentrated their forces in Peru. The people of Jujuy had to endure the Jujuy Exodus, a massive evacuation with a scorched earth policy, led by General Manuel Belgrano. Finally the Spanish surrendered, but the war seriously affected the economy of the area.
After a series of internal conflicts, the province, now separated from Tucumán and Salta, started a gradual economic and social improvement, and at the end of the 19th century sugarcane industry arose. At the beginning of the following century, the railway already connected the province with Buenos Aires, and La Paz, Bolivia.
Industry was impelled first in the 1940s with the construction of the first metal-production furnace in the country, and then in 1969 with the discovering of petroleum by the state-owned YPF.
