The British began to exert colonial control of Nigeria in the early 20th century.
At this time Nigeria had twelve states. Following the civil war, Benue-Plateau State was one of several large states which were further split up following pressure on the Federal Government. Under the military administration of General Yakubu Gowon, the country was further divided into nineteen states in 1976 and Plateau State was created from Benue-Plateau covering the area of the original Plateau Province. In 1996, Plateau State was further subdivided to create Nasarawa State which was carved out of the western half of Plateau State by Sani Abacha's military regime.
