Central African Republic (self-government, independence, empire, and republic)
Who & why: Barthélemy Boganda, founder of the independence movement, wins self-government within the French Community in 1958 and designs the flag himself before dying in a plane crash in March 1959, just short of the independence he had campaigned for; his cousin David Dacko carries the territory to full independence on 13 August 1960. Dacko is overthrown in 1966 by army chief Jean-Bédel Bokassa, who rules with escalating brutality and, in December 1976, crowns himself Emperor Bokassa I of a renamed "Central African Empire" in a lavish, internationally mocked ceremony — state factually, the empire's actual governance changed little besides the title. France backs a 1979 coup that restores Dacko and the republic. Decades of further coups, a 2003–present civil conflict, and a 2013 sectarian crisis follow, but the republic form and this same flag persist throughout.
What it represents: Boganda intended the flag to fuse Europe and Africa — the blue, white, and red of France alongside the green, yellow, and red pan-African colors — with the red vertical stripe symbolizing the blood uniting both continents, and a single gold star for hope and independence.
