The Independent National Electoral Commission (INEC) was established by the 1999 Constitution of the Federal Republic of Nigeria to among other things organize elections into various political offices in the country.
The origin of the INEC goes back to the period before Independence when the Electoral Commission of Nigeria was established to conduct 1959 elections. The Federal Electoral Commission (FEDECO), established in 1960 conducted the immediate post-independence federal and regional elections of 1964 and 1965. The electoral body was dissolved after the military coup of 1966. In 1978, the Federal Electoral Commission was constituted by the regime of General Olusegun Obasanjo, organizing the elections of 1979 which ushered in the Nigerian Second Republic under the leadership of Alhaji Shehu Shagari. It also conducted the general elections of 1983.
In December 1995, the military government of General Sani Abacha established the National Electoral Commission of Nigeria which conducted another set of elections. These elected institutions were not inaugurated before the sudden death of General Abacha on June 1998 aborted the process. In 1998 General Abdulsalam Abubakar's Administration dissolved NECON and established the Independent National Electoral Commission (INEC). INEC organized the transitional elections that ushered in the Nigerian Fourth Republic on May 29, 1999.
