The Revolution of 1930 in Brazil marked a significant political shift, leading to the end of the Old Republic. It was primarily driven by dissatisfaction with the ruling government, particularly the dominance of the Coffee oligarchs and regional elites. The revolution was led by Getúlio Vargas, who aimed to modernize the country and address social inequalities. The conflict began in October 1930, when Vargas and his supporters launched a coup against President Washington Luís. The revolution quickly gained momentum, resulting in the overthrow of the government. By November 1930, Vargas assumed the presidency, initiating a new era of political and economic reforms in Brazil.
