Document 2: Republic of the Congo: Following the revision of the French constitution that established the Fifth Republic in 1958, the AEF dissolved into its constituent parts, each of which became an autonomous colony within the French Community. During these reforms, Middle Congo became known as the Republic of the Congo in 1958 and published its first constitution in 1959.

Document 3: History of the Democratic Republic of the Congo: After an uprising by the Congolese people, Belgium surrendered to the independence of the Congo in 1960. However, the Congo remained unstable because tribal leaders had more power than the central government. Prime Minister Patrice Lumumba tried to restore order with the aid of the Soviet Union as part of the Cold War, causing the United States to support a coup led by Colonel Joseph Mobutu in 1965. Mobutu quickly seized complete power of the Congo and renamed the country Zaire. He sought to Africanize the country, changing his own name to Mobutu Sese Seko, and demanded that African citizens change their Western names to traditional African names. Mobutu sought to repress any opposition to his rule, in which he successfully did throughout the 1980s. However, with his regime weakened in the 1990s, Mobutu was forced to agree to a power - sharing government with the opposition party. Mobutu remained the head of state and promised elections within the next two years that never took place.

Massamba-Débat's regime also invited several hundred Cuban army troops into the country to train his party's militia units and these troops helped his government survive a coup in 1966 led by paratroopers loyal to future President Marien Ngouabi.
