For example, in their analysis of the sources of the conflict, Julie Flint and Alex de Waal say that Colonel Gaddafi, the leader of Libya, sponsored "Arab supremacism" across the Sahara during the 1970s. Gaddafi supported the "Islamic Legion" and the Sudanese opposition "National Front, including the Muslim Brothers and the Ansar, the Umma Party's military wing." Gaddafi tried to use such forces to annex Chad from 1979-81. Gaddafi supported the Sudanese government's war in the South during the early 1980s, and in return he was allowed to use the Darfur region as a "back door to Chad". As a result, the first signs of an "Arab racist political platform" appeared in Darfur in the early 1980s.
