Babangida annulled the elections, leading to mass civilian violent protests which effectively shut down the country for weeks. Babangida finally kept his promise to relinquish office to a civilian-run government, but not before appointing Ernest Shonekan as head of the interim government. Babangida's regime has been considered the most corrupt, and responsible for creating a culture of corruption in Nigeria.
