What happened
From the January 1966 coup onward, Nigeria spent all but a handful of years under military government until 1999. Yakubu Gowon led the country through the Biafran war and its aftermath until his own overthrow in 1975; Murtala Mohammed and then Olusegun Obasanjo followed, and Obasanjo oversaw a return to elected civilian government in 1979, Nigeria's Second Republic. That civilian government lasted barely four years before Muhammadu Buhari seized power in a December 1983 coup, and Ibrahim Babangida then took over from Buhari in 1985. Babangida promised a return to democracy and held a presidential election on June 12, 1993, in which Moshood Abiola was headed toward a decisive win, but Babangida annulled the results before they were fully released, citing alleged irregularities, and triggered civil unrest that killed more than 100 people. Babangida resigned months later under pressure, a weak civilian interim government briefly took over, and Sani Abacha seized power in a November 1993 coup, ruling as one of Nigeria's most repressive military heads of state until his sudden death in June 1998.
Why it matters
Three decades of military rule, punctuated by only one failed four-year civilian interlude, entrenched patterns of centralized, unaccountable governance and let oil revenue flow through a small military and political elite with little independent civilian oversight. The annulment of the 1993 election, widely regarded as Nigeria's fairest vote up to that point, became the clearest single symbol of military rule's illegitimacy and helped galvanize the pro-democracy pressure that finally forced a transition after Abacha's death.
How we know
The 1966 coup that opened this period is documented in contemporary U.S. State Department diplomatic cables, and the 1993 election annulment and the negotiated 1998-1999 transition away from military rule are independently documented in Council on Foreign Relations institutional analysis of Nigerian political history.
