In the postwar period, all significant political power remained concentrated in the FMG. None of the three major ethnic groups had a powerful voice in its executive element, which was disproportionately composed of representatives of middle belt minorities and to a lesser extent of Muslim Yoruba and of Ijaw and Ibibio from the Eastern Region. The Northern Region had been divided into six states in 1967, which left the area without its former power base in the federation. The decision was accepted by northerners in part because of the military government's relative strength in comparison with earlier civilian governments. Acceptance also was motivated by the fact that northerners were less fearful of the Igbo or a southern coalition. Only the Yoruba power base in the west retained its prewar characteristics. The 1967 administrative structure also made national unity attractive to the westerners because, with the creation of a Yoruba state (Kwara) in the north, their position seemed stronger relative to the northerners. Remaining points of conflict included the number of civil service posts to be allotted to each ethnic group and the assignment of civil servants from former regional services to states other than their own.
