Bornu Empire
Finally, after warring with Kanem since the 1370s, the Bulala people forced the Kanembu people under "mai" Omar ibn Idris to relocate to Bornu circa 1380, overcoming attacks from their neighbours (Arabs and Berbers, and the Hausa of modern Nigeria), and marked the transition of the beginning of the Bornu Empire. The once strong Sayfawa dynasty was forced out of Kanem and back into the nomadic lifestyle they had abandoned nearly 600 years ago. With the new centre of the empire at Bornu, it became known as the Bornu Empire.
