Argentine Constitution of 1826

The office of the Supreme Director of the United Provinces of the Río de la Plata, the head of state at the time, was abolished as well.

The provinces stayed united as a country by the Treaty of Pilar, but without any constitution or head of state for the time being.

[1] The Treaty of Benegas between Buenos Aires and Santa Fe included an agreement to call for a new Constituent Assembly, which would work at the city of Córdoba.

The treaty did not mention the political system, which would be discussed at the assembly, nor the reaction to the Luso-Brazilian invasion of the Banda Oriental.

Twelve of the thirteen provinces accepted to hold the Congress in Buenos Aires; San Luis proposed Tucumán.

[4] The Assembly approved a treaty of friendship with Britain in 1825, with the British recognition to the 1816 Argentine declaration of independence.

The Congress accepted as well the declaration of independence of the provinces of the Upper Peru, which became a new country, named Bolivia after the liberator Simón Bolívar.

They called the Congress of La Florida, rejecting the Brazilian annexation and requesting the reincorporation into the United Provinces.

The government of Buenos Aires informed the Brazilian emperor Pedro I of this resolution, and that the national armies would only react in self-defense.

[7] Juan Gregorio de las Heras resigned as governor of Buenos Aires, so Elías Bedoya, representative of Córdoba, proposed a law to create a stable head of state figure, the President of the United Provinces of the Río de la Plata.

[9] Juan Bautista Bustos, governor of Córdoba, rejected the appointment of Rivadavia, and his province retired from the Assembly.
