The first Constitution of Uruguay dates back to 1830. Drafted by the Constituent Assembly, summoned in the Church of La Aguada in 1829,it was sworn by the citizens on 18 July 1830.
This political constitution was in force until 1918, when it was replaced by a new constitutional text.
The 1830 constitution has been regarded as Uruguay's most technically perfect charter. Heavily influenced by the thinking of the French and American revolutions, it divided the government among the executive, legislative, and judicial powers and established Uruguay as a unitary republic with a centralized form of government. The bicameral General Assembly was empowered to elect a president with considerable powers to head the executive branch for a four-year term. The president was given control over all of his ministers of government and was empowered to make decisions with the agreement of at least one of the three ministers recognized by the 1830 constitution.
