The first parliamentary experience began with emperor Pedro II in 1847, and was maintained during the last 42 years of the Empire of Brazil.
The first de jure officeholder was Manuel Alves Branco, Viscount of Caravelas, who was sworn in on 20 July 1847 after the office was formally created by Decree No.
The second occasion on which a parliamentary system was put into practice occurred during the government of president João Goulart, in 1961, due to a constitutional amendment approved by his opponents before the beginning of his term.
The number of ministers was small by current Brazilian standards: there were six, and in 1860 the seventh ministry was created by Legislative Decree No.
