Republic of Guinea (independent)
Who & why: Guinea alone among France's West African territories votes "no" in the September 1958 referendum on de Gaulle's proposed French Community, choosing full immediate independence over continued association with France. Independence comes on 2 October 1958 under Ahmed Sékou Touré, but France responds by abruptly withdrawing aid, technical staff, and equipment, leaving the new state to build institutions largely on its own. Touré governs as an increasingly authoritarian one-party ruler until his death in 1984; Guinea has since passed through further periods of military rule alongside moves toward multiparty government.
What it represents: a red-yellow-green vertical tricolor adopted at independence, Pan-African colors read locally as red for the blood and sacrifice of the independence struggle, yellow for the sun and the country's mineral wealth, and green for its vegetation and the unity of its people.
