President Fulbert Youlou is overthrown in the Republic of the Congo, after a three-day uprising in the capital.

Fulbert Youlou was a Congolese nationalist leader and former Catholic priest who became the first President of the Republic of the Congo upon its independence in 1960.

The Republic of the Congo, also known as Congo-Brazzaville, the Congo Republic or simply the Congo, is a country located on the western coast of Central Africa to the west of the Congo River. It is bordered to the west by Gabon, to the northwest by Cameroon, to the northeast by the Central African Republic, to the southeast by the Democratic Republic of the Congo, to the south by the Angolan exclave of Cabinda, and to the southwest by the Atlantic Ocean.

The Trois Glorieuses was an uprising in Congo-Brazzaville which occurred from August 13 to 15, 1963. The uprising ended the rule of the first Congolese President, Fulbert Youlou, as the opposition trade union movement and Congolese Youth Union struck an alliance with the army.
