[1] He moved the capital from Njimi, Kanem to Kaga, located on the western edge of Lake Chad in present day Borno State, Nigeria.
[1] 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.
The Sayfawa dynasty still had control over both capitals and therefore became more powerful than it ever had been so far, and the Bulala and Kanembu states were merged, but political authority still rested in Bornu.
The empire's leaders, however, remained at Ngazargamu, the Bornu capital, because its lands were more productive agriculturally and better suited to the raising of cattle.
