The Battle of er-Rias took place in 1329, in er-Rias near a town named Mermadjenna in the land of the Hawwars.[1] It was fought between the troops of the Hafsid caliph, Abu Yahya Abu Bakr, and the army of the Zayanid sultan, Abu Tashfîn, commanded by Yahya Ibn Moussa and Omar Ibn Hamza (leader of the nomadic tribes of Ifriqiya) as well as the Hafsid prince Mohamed Ibn Abu Umran, who had been the governor of Tripoli. The prince was declared caliph of the Hafsids and the army marched east.
