[1] The old Nupe Kingdom was established in the middle of the 15th century in a basin between the Niger and Kaduna rivers in what is now central Nigeria.
After Ma’azu's death and during the subsequent wars of succession, the Nupe Kingdom came under the control of the Gwandu Emirate.
During his second period of rule, Masaba established the Bida Emirate as an important military power, steadily expanding its territory at the expense of its neighbors to the south and east.
His successors retained control until 1897, when British Niger Company troops finally took Bida and established a puppet ruler.
The Bida emirate became subject first to the British colonial regime, then to the independent state of Nigeria, with its rulers playing an increasingly ceremonial role.
