Zab

The Zab was an oasis emirate centred on Biskra in eastern Algeria, ruled by the Banu Muzni. After resubmitting in 1329, they gave the Hafsids largely nominal obedience.

In 1401 a Hafsid army defeated the Zab before Biskra and captured Emir Ahmed ibn Yusuf, ending the emirate. The chiefs of Biskra later accepted Ottoman overlordship under the Pact of Barbarossa in 1541.
