Republic of Tucumán

1820 CE – 1821 CE · capital San Miguel de Tucumán

A short-lived provincial republic in northwestern Argentina created by the caudillo Bernabé Aráoz during the anarchy of 1820.

Origins

After central government in the United Provinces of the Río de la Plata collapsed in 1820, the governor of Tucumán, Bernabé Aráoz, proclaimed the Republic of Tucumán. It claimed the provinces of Tucumán, Catamarca and Santiago del Estero, and adopted a constitution that year.

Rule and society

Aráoz governed as supreme president, seeking to keep the northern provinces together under Tucumán's leadership. Santiago del Estero, under Juan Felipe Ibarra, rejected his authority and declared its own autonomy, and the two sides went to war. Catamarca also broke away. The republic faced constant conflict with Salta, governed by Martín Miguel de Güemes.

Decline and legacy

Aráoz was overthrown in 1821, and the republic dissolved into the separate provinces of Tucumán, Catamarca and Santiago del Estero, which later joined the Argentine Confederation. Aráoz was executed in 1824.
