The Efik are an ethnic group located in the Southern part of Cross River State, Nigeria. The Efik migrated down the Cross River from Cameroon in the 16th century and founded numerous settlements in the Calabar area in present-day Cross River State. Calabar is not to be confused with the Kalabari Kingdom in Rivers State which is an Ijaw state to its west. Cross River State was formerly one of the original twelve states of Nigeria known as the Southeastern State. The Efik people also occupy Southwestern Cameroon including Bakassi. While in the then Eastern Region of Nigeria prior to the civil war, the region allowed Southwestern Cameroon to be partitioned out of Nigeria into Cameroon through the 1961 plebiscite which divided them into Nigeria and Cameroon.
