The revolt was caused by Vargas' appointment of João Alberto, a center-left "tenente" as "interventor" (provisional governor) in place of the elected governor of São Paulo. The paulista elite loathed Alberto, resenting his centralization efforts and alarmed by his economic reforms, such as 5% wage increase and the minor distribution of some land to participants of the revolution. Amid threats of revolt, Vargas replaced João Alberto with a civilian from São Paulo, appointed a conservative paulista banker as his minister of finance, and announced a date for the holding of a constituent assembly. This only emboldened coffee oligarchs who launched a revolt in July 1932, which collapsed after three months of armed combat.
