The Brazilian military junta of 1930, also known as the Pacification Junta (Portuguese: Junta Pacificadora), seized power during the Revolution of 1930 and governed Brazil from 24 October to 3 November 1930, when the junta leaders handed power over to revolutionary leader Getúlio Vargas.
The First Brazilian Republic was dominated by an oligarchy that manipulated elections and handpicked the Brazilian presidency. This oligarchy, between politicians from the states of Minas Gerais and São Paulo, was broken when President Washington Luís nominated Júlio Prestes to succeed him. Backed by military rebels, Minas Gerais responded by forming the Liberal Alliance with Paraíba and Rio Grande do Sul, which nominated Getúlio Vargas for the presidency. When Prestes won the March 1930 election, the alliance claimed electoral fraud and orchestrated an armed revolution beginning on 3 October 1930. In Rio de Janeiro, then capital of Brazil, Generals Augusto Tasso Fragoso, head of the junta, João de Deus Mena Barreto, and Admiral Isaías de Noronha decided that Luís had to be removed from the presidency in order to prevent a civil war.
Luís was ousted by the military leaders, who took control of Brazil as a provisional governing body on 24 October, claiming to be the sole power in the country, despite only controlling Rio de Janeiro. The junta initially considered retaining power, but negotiated with revolutionaries to transfer power to Vargas on 3 November 1930 after his arrival in Rio de Janeiro.
