Brazil promulgated a new national constitution following the collapse of the Old Republic. It introduced major social reforms, including labor rights such as minimum wage protections and limits on working hours. The constitution also expanded voting rights by allowing women to vote for the first time at the national level. It strengthened federal authority while maintaining a republican framework. Although progressive, the constitution remained in force for only three years. It was replaced in 1937 when Getúlio Vargas established the Estado Novo regime.
