Calabar in the context of "Cross River (Nigeria)"

The Efik are an ethnic group located primarily in southern Nigeria, and western Cameroon. Within Nigeria, the Efik can be found in the present-day Cross River State. The Efik speak the Efik language which is a member of the Benue–Congo subfamily of the Niger-Congo language group. The Efik refer to themselves as Efik Eburutu, Ifa Ibom, Eburutu and Iboku.

The bulk of the Efiks can be found in Calabar and the southern part of Cross River State. Prior to 1905, Old Calabar was a term used to describe the Efik settlements of Duke Town, Creek Town, Old town, Cobham town, Henshaw town, Adiabo and Mbiabo (consisting of Mbiabo edere, Mbiabo Ikot Offiong and Mbiabo Ikoneto). The Efik have also been referred to as "Calabar people" in historical literature. The term "Calabar people" was particularly popular prior to the nineteenth century and was synonymous with the Efik.

The Eastern Region was an administrative region in Nigeria, dating back originally from the division of the colony Southern Nigeria in 1954. Its first capital was Calabar. The capital was later moved to Enugu and the second capital was Umuahia. The region was officially divided in 1967 into three new states, the East-Central State, Rivers State and South-Eastern State. East-Central State had its capital at Enugu, which is now part of Enugu State.

The region had the country's third-, fourth- and fifth-largest indigenous ethnic groups including Igbo, Ibibio and Ijaw, respectively. It was what later became Biafra, which was in rebellion from 1967 to 1970.

The history of Nigeria can be traced to the earliest inhabitants whose date remains at least 13,000 BC through the early civilizations such as the Nok culture which began around 1500 BC. Numerous ancient African civilizations settled in the region that is known today as Nigeria, such as the Kingdom of Nri, the Benin Kingdom, and the Oyo Empire. Islam reached Nigeria through the Bornu Empire between (1068 AD) and Hausa Kingdom during the 11th century, while Christianity came to Nigeria in the 15th century through Augustinian and Capuchin monks from Portugal to the Kingdom of Warri. The Songhai Empire also occupied part of the region. Through contact with Europeans, early harbour towns such as Calabar, Badagry, and Bonny emerged along the coast after 1480, which did business in the transatlantic slave trade, among other things. Conflicts in the hinterland, such as the civil war in the Oyo Empire, meant that new enslaved people were constantly being "supplied".

After 1804, Usman dan Fodio unified an immense territory in his jihad against the superior but quarrelling Hausa states of the north, which was stabilised by his successors as the "Caliphate of Sokoto".
