This document provides background on Libya's descent into a failed state following its 2011 revolution. It describes the divisions in Libya along ideological, regional and tribal lines that have led to ongoing conflict. It notes that Libya initially showed signs of progress after the revolution, with political and economic development as well as integration of former rebels. However, armed militias increasingly exerted influence and undermined state authority. Competing governments now control parts of Libya, the country is divided, and terrorist groups have gained a foothold. Outside powers have also intervened militially while supporting opposing factions. As a result, Libya meets the criteria of a failed state with no central authority over its territory or monopoly on the use of force.
