Ahmad ibn Abi Dabbus
Ahmad ibn Abi Dabbus was an Almohad prince descended from Abu Dabbus Idris II, the last Almohad caliph, killed at Marrakesh in 1269. After his family's failed bid for the Hafsid throne brought exile in Egypt in 1344, he returned to Ifriqiya and settled in Tozeur as a tailor.
In 1348, as Arab rebels defeated the Marinid sultan, the Ku'ub found the tailor and proclaimed him sultan. With Ibn Tafragin he besieged Tunis, but his allies deserted him; he was handed to the Marinid sultan and later went to Spain.
