The Brazilian Constitution of 1946 was enacted on September 18, 1946, following the end of the Estado Novo regime led by Getúlio Vargas. This constitution marked Brazil's return to democracy after a period of authoritarian rule and aimed to establish a framework for civil liberties, political rights, and social justice. The 1946 Constitution introduced a parliamentary system and emphasized individual rights, including freedom of speech and assembly. It also recognized the importance of labor rights and social welfare, reflecting the influence of the New Deal policies. This constitution remained in effect until it was replaced by the Brazilian Constitution of 1988.
