Gubio

Gubio lies in the plains of Bornu, west of Lake Chad. The country around it belonged to a kingdom whose rulers and merchants were connected to the Sahara and the central Sudan. Farther west stood Ngazargamu, the capital founded by Mai Ali Gaji in the fifteenth century. Its markets drew caravans from North Africa and neighbouring regions, while the town's fortified walls enclosed the court of Bornu.
