Question: When did the Kamananga's country become independent?

full_context: Document 1: Republic of the Congo: Under the 1963 constitution, Massamba-Débat was elected President for a five-year term. During Massamba-Débat's term in office the regime adopted "scientific socialism" as the country's constitutional ideology. In 1965, Congo established relations with the Soviet Union, the People's Republic of China, North Korea and North Vietnam. 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. Nevertheless, Massamba-Débat was unable to reconcile various institutional, tribal and ideological factions within the country and his regime ended abruptly with a bloodless coup d'état in September 1968.

During these reforms, Middle Congo became known as the Republic of the Congo in 1958 and published its first constitution in 1959. Antagonism between the pro-Opangault Mbochis and the pro-Youlou Balalis resulted in a series of riots in Brazzaville in February 1959, which the French Army subdued.

Document 7: 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.
