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.
There are a number of different versions of the legend with Kisra sometimes being depicted as a religious and military rival to Muhammad near Mecca around the time that Islam was founded and sometimes as the remnant forces of a Persian king defeated in Egypt.
[1] In the most prominent version of the story in the Borgu kingdom, Kisra is depicted as an early political and religious challenger to Muhammad in the area around Mecca.
[3] In 1909, the German anthropologist Leo Frobenius compiled an aggregate version of the Kisra legend from informants in the Benue river valley.
This version depicts Kisra not as a challenger to Mohammad, but instead as a Persian king who suffered a military defeat in Egypt to a Byzantine army.
His army settled briefly in Nubia and Ethiopia where Kisra joined forces with a powerful king in the region, Napata, to conquer lands to the West.

The legend was a key part of developing clear cultural identity in Borgu and Kebbi as they resisted Songhai and Fulani dominance to the north.
[16] These theories argued that political development, namely the formation of complex states, had its origins in migrations of people from the Middle East or of Christian influences (often Coptic).
