Problem: Nigeria regained democracy in 1999 when it elected Olusegun Obasanjo, the former military head of state, as the new President of Nigeria. This ended almost 33 years of military rule (from 1966 until 1999), excluding the short-lived second republic (between 1979 and 1983) by military dictators who seized power in coups d'état and counter-coups during the Nigerian military juntas of 1966–1979 and 1983–1998.
