The United Somali Congress (USC) was one of the major paramilitary organizations and political party in Somalia. Formed in 1987, it played a key role in the ouster of the government of Siad Barre in 1991, and became a target of the Unified Task Force campaign in 1993. Following infighting, the USC later splintered into smaller groups. By 2004, with the establishment of a Transitional National Government (TNG), a process of disarmament was put in motion and some moderate ex-USC leaders were incorporated into the new interim administration.
