Republic of Togo (independent)
Who & why: French Togoland becomes the independent Republic of Togo on 27 April 1960, the first of the 1960 wave of French West African independences. Sylvanus Olympio, the country's first president, is assassinated in a 1963 coup, and Gnassingbé Eyadéma comes to power in a further 1967 coup, going on to rule for nearly four decades — one of the longest presidencies in African history — before a family succession in 2005.
What it represents: a flag designed by Paul Ahyi, adopted at independence: five alternating green-and-yellow horizontal stripes for the country's provinces and for agriculture and mineral wealth, and a red canton with a white star symbolizing the struggle for independence and hope for the future.
