Ibrahim Badamasi Babangida (born August 17, 1941), also known as IBB, is a retired Nigerian Army General who was President of Nigeria under military rule. He ruled Nigeria from August 27, 1985, when he overthrew Major General Muhammadu Buhari in a coup, until his departure from office on August 27, 1993, having annulled the elections held on June 12 that year. General Babangida was a key player in most of the military coups in Nigeria (July 1966, February 1976, December 1983, August 1985, December 1985 and April 1990). There is evidence of severe human rights abuses during his regime.
