The national flag of the Republic of the Congo (French: drapeau de la république du Congo) consists of a yellow diagonal band divided diagonally from the lower hoist-side corner, with a green upper triangle and red lower triangle. Adopted in 1959 to replace the French Tricolour, it was the flag of the Republic of the Congo until 1970, when the People's Republic of the Congo was established. The new regime changed the flag to a red field with the coat of arms of the People's Republic in the canton. This version was utilized until the regime collapsed in 1991. The new government promptly restored the original pre-1970 flag.
