Background and detail

Background. The Assembly of the Year XIII, also known as the General Constituent and Sovereign Assembly, was convened by the Second Triumvirate. It met in Buenos Aires from 31 January 1813 to 24 January 1815. The Second Triumvirate decreed the number of deputies for the capital and provinces on 24 October 1812, with special recognition for San Miguel de Tucumán due to its victory over royalist forces.

Inaugural Session. On 31 January 1813, the Assembly's first session declared its deputies as representatives of free and united provinces. It asserted the representation of popular sovereignty and established its purpose to draft a constitution. The session elected its president and secretaries, with Valentín Gómez and Hipólito Vieytes appointed as deputy secretaries by the Triumvirate on that same day.

Initial Composition. The Assembly's initial membership included deputies from Buenos Aires, such as Hipólito Vieytes, Valentín Gómez, and Vicente López y Planes. Deputies from Córdoba, Corrientes, and Tucumán also joined early. The composition reflected the political importance of various regions, with specific appointments and replacements occurring throughout the first months of the Assembly's operation.

Banda Oriental Representation. The Assembly suspended the incorporation of deputies from the Banda Oriental on 5 March 1813, citing doubts about the formal procedure of their election at the Congress of Tres Cruces. Negotiations with leader José Gervasio Artigas failed, leading to the rejection of most Oriental deputies in June 1813.
