Ogoni nationalism is a political ideology that seeks self determination by the Ogoni people. The Ogonis are one of the many indigenous peoples in the region of southeast Nigeria. They number about 1.5 million people and live in a 404-square-mile (1,050 km2) homeland which they also refer to as Ogoni, or Ogoniland. They share common oil-related environmental problems with the Ijaw people of Niger Delta.
