Answer Details
The twelve state structure was created in Nigeria in 1967. It was created by the then military government of Nigeria, headed by General Yakubu Gowon, in response to the demands of various ethnic groups in the country for more equitable distribution of resources and power. Prior to this, Nigeria was divided into four regions, which were seen as favoring the larger ethnic groups in the country. The creation of 12 states was aimed at giving more representation and autonomy to the smaller ethnic groups, and also to promote national unity and development.
