Legality Campaign
The Legality Campaign (Portuguese: Campanha da Legalidade; also known as Legalidade) was a civil and military mobilization in 1961 to ensure the inauguration of João Goulart as President of Brazil, overturning the veto of the Armed Forces' ministers to the legal succession of president Jânio Quadros, who had resigned, to then vice president Goulart. It was led by the governor of Rio Grande do Sul, Leonel Brizola, allied with the commander of the 3rd Army, general José Machado Lopes.
