Ijo also known as Ijaw or Izon, are a collection of peoples indigenous mostly to the forest regions of the Bayelsa, Delta, and Rivers States within the Niger Delta in Nigeria. Some are resident in Akwa-Ibom, Edo, and Ondo states also in Nigeria. Many are found as migrant fishermen in camps as far west as Sierra Leone and as far east as Gabon along the Western Africa coastline. The Ijo population is estimated to be over 10 million people. They have long lived in locations near many sea trade routes, and they were well connected to other areas by trade as early as the 15th century.
Ijo is not currently taught on the IU campus.
