In 1975, General Yakubu Gowon was deposed and General Murtala Mohammed was the head of the Federal Military Government of Nigeria until his assassination in 1976. On his death, the chief-of-staff, Supreme Headquarters (equivalent to a vice-president) general Olusegun Obasanjo assumed office of head of state in a meeting of the Supreme Military Council, keeping the chain of command established by Murtala Muhammed in place. Gen. Obasanjo was responsible for completing the democratic transition begun by his predecessor, which culminated in an election in August 1979.
