Presidential elections were held in Nigeria on 12 June 1993. The elections were the first held since the 1983 military coup d'état which ended the Second Nigerian Republic. They were the culmination of a transition from military to civilian rule spearheaded by incumbent president Ibrahim Babangida. However, the results were annulled by the military government, citing electoral irregularities, when unofficial returns indicated a substantial victory for Moshood Abiola of the Social Democratic Party over his opponent, Bashir Tofa of the National Republican Convention.
