Sebou River
The Battle of Bagdoura (or Baqdura) was a decisive confrontation in the Berber Revolt in late 741 CE. It was a follow-up to the Battle of the Nobles the previous year, and resulted in a major Berber victory over the Arabs by the Sebou River (near modern Fes). The battle would permanently break the hold of the Umayyad Caliphate over the far western Maghreb (Morocco), and the resulting retreat of elite Syrian forces into Spain would have implications for the stability of al-Andalus.
