Kisra legend
The Kisra legend is a migration story shared by a number of political and ethnic groups in modern Nigeria, Benin, and Cameroon, primarily the Borgu kingdom and the people of the Benue River valley. The migration legend depicts the arrival of a large military force in what is currently Northern Nigeria around the 7th century AD. The Borgu kingdom claimed direct descent from the leader of this migration and a number of other polities recognize the migration through ceremony and formal regalia.
