A "ditadura militar" refers to a military dictatorship, a form of government where the military controls the state, often suspending civil liberties and political rights. This type of regime typically arises during times of political instability or conflict, with military leaders justifying their rule as necessary for national security. In Brazil, the "ditadura militar" lasted from 1964 to 1985, marked by repression, censorship, and human rights violations. The government suppressed dissent and targeted political opponents, leading to widespread fear and resistance among the population. The period ended with a gradual return to democracy, influenced by both internal and external pressures.
