The Congress of Angostura was convened by Simón Bolívar and took place in Angostura (today Ciudad Bolívar) during the wars of Independence of Colombia and Venezuela, culminating in the proclamation of the Republic of Colombia (historiographically called Gran Colombia ). It met from February 15, 1819, established the new independent-from-Spain nation on December 17, was interrupted by further independentist activity, and reconvened on July 31, 1821, when the Congress of Cúcuta began its sessions. The Angostura assembly consisted of twenty-six delegates representing Venezuela and New Granada (today Colombia).
