Gambaru
Gambaru lies in Bornu country southwest of Lake Chad, near Ngala and the lands across the Elbeji. The wider region formed part of the world of Kanem-Bornu, whose rulers bore the title mai. After the Sayfawa dynasty lost its old heartland east of the lake, its rulers established a new capital at Ngazargamu farther west. Bornu's ties across the Sahara connected the lake basin with merchants and scholars from distant lands.
