The Bilala or Bulala are a Muslim people that live around Lake Fitri, in the Batha Prefecture, in central Chad.

These three peoples are collectively known as Lisi and are believed to be descendants of main ethnic groups of the Sultanate of Yao.

They were originally a political entity that came about as a result of fusion of the Kayi (old Zaghawa = current Kanembu, the clan exist even today in Kanem) and Ngizimis Kanembu clan, which exists even today in Dibbinintchi, Lake Chad inhabitants of the Fittri region.

Kanem was retaken by Ali's son after a great battle at Garni Kiyala, forcing the Bulala to move east, where they were to remain a menace for centuries to Kanem-Bornu.

It continued also to be a flourishing kingdom: the traveller Leo Africanus even thought that the Bulala's reign was richer than Kanem–Bornu for its prosperous trade with Egypt.
