The Battle of Chelif River was fought on 17 October 1015 between the Zirid army of Badis ibn Mansur, the Emir of ifriqiya, and the Hammadid army under the Hammadid Emir Hammad ibn Buluggin and his brother Ibrahim. This battle was part of the Zirid-Hammadid war which resulted in the splitting of the previous Zirid domains into two independent emirates. It took place near the medieval city of Tahert located in the south of Chelif River, and was a decisive Zirid victory. Badis's army, composed of allies from the berber tribes inhabiting the region, crossed the Chelif River and established their base near its banks. On October 17, 1015, the Zirid army advanced towards the Hammadid camp. The largely unexpected attack led by the Zirid emir resulted in a bloody battle during which the Zenata forces switched sides to Badis. Ultimately, the Zirid army overwhelmed the Hammadid forces, although Emir Hammad himself survived the defeat. Following their victory, the Zirids looted the camp, gathered supplies, and took hostages.
