Kashim Bir succeeded his brother Kade I as mai, and was himself succeeded by either Jalil or Bir II Ibrahim.

Bosworth (1996) considers Kashim Bir and Bir II Ibrahim to be the same figure whereas Cohen (1966) and Stewart (1989) separate the two.

Kashim Bir's consort was named Kagudi. They had at least one son together, Ibrahim I Nikale, who would later claim the Kanem–Bornu throne.
