The Efik are an ethnic group located primarily in southeastern Nigeria. 'Efik' is also the name of their language which is a variation of the Ibibio language. 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. This area along with present-day Akwa Ibom State are usually referred to as Calabar, and Calabar people accordingly, after the European name Calabar Kingdom given to their state of Akwa Akpa. Calabar is not to be confused with the Kalabari Kingdom in Rivers State which is an Ijaw state to its west. Cross River State and Akwa Ibom State were formerly one of the original twelve states of Nigeria known as the Southeastern State.

The Efik people as well as their Annang and Ibibio brothers and sisters 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 (Efik, Ibibio and Annang) into Nigeria and Cameroon.

Donald Duke (born 30 September 1961 in Calabar) was the Governor of Cross River State, Nigeria from 29 May 1999 to 29 May 2007. He received LLB degree in 1982 from Ahmadu Bello University, Zaria - Nigeria, the B.L in 1983 from the Nigerian Law School, Lagos and the L.L.M. in Business Law and Admiralty in 1984 from University of Pennsylvania.

Spearheading the incumbent debt of Nigeria, Duke pushed for democracy and against military control. He stated; "What got the military out of power was not democracy but the dreadful state of the economy. If we, the democratic government, cannot deliver food for the mass of people we can forget about democracy."

Duke has been praised for his contributions to the fields of agriculture, urban development, government, environment, information and communication, investment drive, and tourism. Through his work Calabar is seen as the "cleanest city in Nigeria."^{[citation needed][dead link]}

He created the idea of the Obudu Ranch International Mountain Race and the race grew to become one of the most lucrative mountain running competitions in the world under his stewardship.

P-Square are a Nigerian R&B duo composed of identical twin brothers Peter and Paul Okoye.

The story of P-Square began in St. Murumba secondary school, a small Catholic school in Jos, Nigeria. Identical twins Peter and Paul joined their school music and drama club where they began singing, dancing, and miming songs by MC Hammer, Bobby Brown and Michael Jackson.

They later formed an a cappella quartet called "MMMPP" (M Clef a.k.a. Itemoh, Michael, Melvin, Peter and Paul). Drawing inspiration from their music idol Michael Jackson, they began break dancing, formed the group called "Smooth Criminals" in 1997. They droped M Clef from the group "MMMPP" which later was changed to "MMPP". Their artistic talent and precise dance routine soon made them household names in the city of Jos, where they performed at school functions and other occasions.

Later in 1999, Peter and Paul returned to music school to develop their skills on keyboard, drums, bass and rhythm guitar. Their work includes the soundtracks for a number of films like Tobi, Mama Sunday, Moment of Bitterness and Evas River.
