The National Council of Government (Spanish: Consejo Nacional de Gobierno) was the ruling body in Uruguay between 1952 and 1967. It consisted of nine members, of which six were from the party that received the most votes in general elections, and three from the runner-up party. Generally known as the colegiado system, it had previously existed as the National Council of Administration (Spanish: Consejo Nacional de Administración) between 1918 and 1933.
The colegiado system had been first proposed by President José Batlle y Ordóñez in 1913, with the aim of creating an executive body similar to the Swiss Federal Council. Batlle had been opposed to the presidential system, believing that a collegiate body would lower the risk of a dictatorship emerging. Although the proposal was defeated in 1916, Batlle negotiated a compromise with the National Party to include the system in a new constitution approved in a 1917 referendum.
The compromise provided for a President and a nine-member National Council of Administration (NCA), which consisted of six members of the winning party and three from the second party. The President was responsible for foreign affairs, national security and agriculture, whilst the NCA oversaw the budget, education, healthcare, industry, industrial relations, labour, livestock and public works. Chairmen of the NCA (Prime Ministers) included ex-presidents Feliciano Viera, José Batlle y Ordóñez and Baltasar Brum.
Although the new system worked well in its early years, in the early 1930s a series of conflicts between the President and the NCA led to a presidential coup by Gabriel Terra in 1933. A new constitution was drawn up, which abolished the NCA, and was approved in a 1934 referendum. However, the new constitution provided for a nine-member Council of Ministers, in which the second party was guaranteed three members.
