The National Resistance Army (NRA) was a guerilla army and the military wing of the National Resistance Movement (NRM) that fought in the Ugandan Bush War against the government of Milton Obote, and later the government of Tito Okello. NRA was supported by Muammar Gaddafi.
NRA was formed in 1981 when Yoweri Museveni's Popular Resistance Army (PRA) merged with ex-president Yusuf Lule's group, the Uganda Freedom Fighters (UFF). Museveni, then leader of the Uganda Patriotic Movement party, alleged electoral fraud and declared an armed rebellion, following the victory of Uganda Peoples Congress in the bitterly disputed 1980 general election.
