In 1977, Gaddafi dissolved the Republic and created a new socialist state, the Jamahiriya ("state of the masses"). Officially adopting a symbolic role in governance, he retained power as military commander-in-chief and head of the Revolutionary Committees responsible for policing and suppressing opponents. Overseeing unsuccessful border conflicts with Egypt and Chad, Gaddafi's support for foreign militants and alleged responsibility for the Lockerbie bombing led to Libya's label of "international pariah". A particularly hostile relationship developed with the United States and United Kingdom, resulting in the 1986 U.S. bombing of Libya and United Nations-imposed economic sanctions. Rejecting his earlier ideological commitments, from 1999 Gaddafi encouraged economic privatization and sought rapprochement with Western nations, also embracing Pan-Africanism and helping to establish the African Union. Amid the Arab Spring, in 2011 an anti-Gaddafist uprising led by the National Transitional Council (NTC) broke out, resulting in the Libyan Civil War. NATO intervened militarily on the side of the NTC, bringing about the government's downfall. Retreating to Sirte, Gaddafi was captured and killed by NTC militants.
