Samuel Doe, the 21st President of Liberia, was executed following his capture by rebel forces led by Prince Yormie Johnson.
Doe had seized power through a military coup d'état on 12th April 1980 killing the President, William R. Tolbert, Jr, and establishing himself as the first "indigenous" head of state since the formation of Liberia on 16th July 1847.
