Since Nigerian independence in 1960, there have been five military coup d'états in Nigeria. Between 1966 and 1999, Nigeria was ruled by a military government without interruption, apart from a short-lived return to democracy under the Second Nigerian Republic of 1979 to 1983. However, the most recent coup occurred in 1993, and there have been no significant further attempts under the Fourth Nigerian Republic, which restored multi-party democracy in 1999.
