1966 Republic of the Congo coup d'état attempt
For 10 days in June and July, 1966 an attempted coup took place in the Republic of the Congo. The coup was sparked following the demotion of Marien Ngouabi (the future President) who was accused of insubordination. Ngouabi's elite unit of paratroopers took over part of the capital, Brazzaville and were successful at cutting of the city's telecommunications and transportation. A group of over 200 Cuban army troops, then resident in Brazzaville, protected the government's radio station as well as the Congolese government against the rebelling paratroopers. When President  Alphonse Massamba-Débat returned to the country on 3 July he was greeted at the airport by members of his government and not by the military, which was customary. Soviet, American, West Germany, Belgian, and French diplomats who were present all agreed that the Cuban army's presence in the capital had prevented the overthrow of the regime.
