The Brazilian Constitution of 1967 was enacted during a military regime that began in 1964. It aimed to consolidate the powers of the military government while limiting civil liberties. The constitution introduced a centralized government structure and emphasized national security, reflecting the political climate of the time. This constitution replaced the previous Brazilian Constitution of 1946 and remained in effect until it was replaced by the Brazilian Constitution of 1988. Although it provided some social rights, it primarily served to legitimize the military's authority and suppress dissent during a period marked by political repression.
