Isu people

The Isu people are the largest group of the Igbo people of Nigeria. Isuama, in which the purest Igbo is said to be spoken, is to be found the heart of the Igbo nationality; consequently it is quite reasonable to look among its people for the original fountain-head from which all the other clans have sprung. This inference too is supported not only by the purity of the language, but by this right of dispensing or rather of confer-ring royalty which is undoubtedly the prerogative of the Nri or N'shi people. In the pre-colonial era, the Igbo people were protected from external invasion by the dense forests of the region, which also encouraged diversity. Thus as warriors the neighboring Oratta (Uratta) people (Owerri people) looked down on the Isu people, who were traders.

Isuama is the name given to the south-central part of Igboland, which was a major source of slaves during the period of the trans-Atlantic slave trade. The name has been carried across the Atlantic, where it is found in the name of Cuban society Carabali Isuama. This name pays homage to the group's ancestry in the Isuama area of Igboland to the north of the Kalabari Ijaw people. At one time the Isuama language was spoken in Cuba, but eventually it and other Cross River languages was displaced by the standard Abakua language called Brikamo.
