The Club 3 de Outubro, overlooked by most studies of the Brazilian revolution of 1930, played a central role in the tenente movement and in the revolution itself. The 1930s were a watershed in modern Brazilian history, when state, society, and economy were altered, sometimes radically. Although some of the changes were responses to the Depression and international conditions, the revolution as a political phenomenon was a dominant force in shaping contemporary Brazil. State authorities ceded power to the Central Government's interventors (delegates), counteracting Brazil's strong regionalist tradition and assuring the dominance of national institutions. In addition, urban voters in the 19305 for the first time had an influential voice in politics, sometimes as allies of the tenentes. The army, strengthened and unified vis-à-vis the state militias, was subordinated to the Federal Government.
