Following the Brazilian Revolution of 1930, a constitutional assembly was elected in 1933 and drew up a new constitution, which came into force on 16 July 1934.[2] It provided for a federal state with a bicameral parliament consisting of a 300-member Chamber of Deputies (of which 250 were directly elected and 50 selected by union and employer bodies) and a Senate consisting of two members from each state, who would be elected by state legislatures.[2][3]
After the constitution was promulgated, the Assembly was converted into a Chamber of Deputies and electedGetúlio Vargas as president the following day.[2]
The 250 directly elected members were elected by open listproportional representation, with states acting as constituencies.[3][4] Voters could cast preferential votes for candidates from multiple parties.[4]
