3 July 1990
Liberian President, Samuel Kanyon Doe offered to resign in response to rebel incursions in his country. Doe was eventually kidnapped during a truce meeting, tortured and on 9 September he was executed by his kidnapers. His execution was recorded on video. Charles Taylor, who would later face charges of crimes against humanity at the International Criminal Court (ICC), became head of the Provisional Government. In April 1980, Doe overthrew William Tolbert Jr in a bloody coup. He subsequently established, for the first time in Liberia’s history, military rule over the country. On 26 April 2012, Taylor was found guilty by the Special Court for Sierra Leone on 11 charges of aiding and abetting the rebels who went on a bloody rampage during the decade-long war that ended in 2002 with more than 50 000 dead.
