Charles Taylor, a former ally of Doe, crossed into Liberia from the Ivory Coast on December 24, 1989, to wage a guerrilla war against Doe. Taylor had broken out of a jail in the United States, where he was awaiting extradition to Liberia on charges of embezzlement. The conflict quickly flared into full-fledged civil war. By mid-1990, most of Liberia was controlled by rebel factions.
