The major event that took place in Brazil in 1964 was the military coup known as the "Gerão de Junho" (June Coup). This event marked the overthrow of the democratically elected President, Jânio Quadros, by a group of generals led by General Gustavo Prado. Maj. Gustavo Câmara was another key figure in the coup.
The coup was triggered by several factors, including economic issues, social unrest, and the perception that President Quadros was unable to handle these challenges. The military junta, which took power after the coup, established a military dictatorship that lasted until 1985. During this period, human rights abuses, censorship, and political repression were common.
The coup had a significant impact on Brazilian politics and society, as it led to the suppression of political opposition and the suppression of civil liberties for almost two decades. In 1985, amidst growing protests and dissatisfaction among the population, the military government relinquished power and Brazil returned to a democratic system with the election of President João Figueiredo.

The major event that took place in Brazil in 1964 was the military coup known as the "Gerança" or "Gerança de 1964". This event marked the overthrow of the democratic President Juscelino Kubitschek de Oliveira (known as Jânio Quadros) by the Brazilian military. Military الجنرال Gustavo Rio de Andrade became the interim president, but he resigned after just a few months due to health reasons.
The coup was carried out by a group of military leaders, including General Emilio Goldfus, General Castelo Branco, and General Goulart. These generals formed a junta, which ruled Brazil until 1985, when the military government was gradually replaced by a civilian administration.
The coup was influenced by political instability, economic issues, and a deepening rift between the military and the civilian government. The military regime that followed implemented strict censorship, limitations on political freedoms, and a policy of social control and development projects. While these policies led to significant infrastructure improvements, they also resulted in human rights abuses, corruption, and political oppression. The military regime ended with the 1985 Presidential election, which led to the establishment of a civilian government and the beginning of a transition to democracy in Brazil.

During this time, the military took over the government, overthrowing the democratically elected President, Juscelino Kubitschek. The military dictatorship lasted until 1985 and is considered one of the darkest periods in Brazilian history.

However, the dictatorship was marked by authoritarian rule, and opposition to the regime grew over time. The country experienced significant social and economic changes during this period, which included rapid industrialization and the expansion of the Brazilian economy.
