The Kingdom of Benin or Empire of Benin, also known as Great Benin, is a traditional kingdom in southern Nigeria. It has no historical relation to the modern republic of Benin, which was known as Dahomey from the 17th century until 1975. The Kingdom of Benin's capital was Edo, now known as Benin City in Edo State, Nigeria. The Benin Kingdom was one of the oldest and most developed states in the coastal hinterland of West Africa. It grew out of the previous Edo Kingdom of Igodomigodo around the 11th century AD; it was annexed by the British Empire in 1897, but endured as a non-sovereign monarchy.
