General elections were held in Brazil on 1 March 1930. In the presidential elections the result was a victory for Júlio Prestes of the Republican Party of São Paulo, who received 57.7% of the vote.
Prestes never took office as he was overthrown by the Brazilian Revolution on 24 October. The revolution was led by Vargas, an opponent of the oligarchic rule shared between the states of São Paulo and Minas Gerais (known as the café com leite system). Vargas became President of Brazil, ruling until 1945.
