Brazil's military dictatorship lasted from 1964 to 1985, following a coup that overthrew President João Goulart. The military government aimed to suppress leftist movements and maintain political stability, leading to the implementation of strict censorship, political repression, and human rights violations. During this period, the regime promoted economic growth through industrialization but also faced widespread protests and resistance. The dictatorship ended in 1985, transitioning Brazil back to civilian rule and paving the way for a democratic government, which has since worked to address the legacy of the military era.
