After a disputed election brought Milton Obote to power in Uganda in 1980, one of his opponents, Yoweri Museveni, led an armed resistance against the government. The subsequent Ugandan “Bush War” between Museveni’s National Resistance Army (NRA) and the government’s Uganda National Liberation Army (UNLA) lasted from 1981 to 1986. In 1983, ethnic tensions began to fracture the UNLA.

President Obote, an ethnic Lango, was accused of favoritism at the expense of the Acholi, who mostly comprised the officer corps. After confronting Obote with these and other complaints, General Tito Okello staged a coup d’état with the help of a group of Acholi. Okello ousted Obote and installed himself as president on July 27, 1985. Okello was later ousted himself by Museveni and the NRA six months later. Today marks the start of the 40th year since Tito Okello’s rulership.
