Hammu ibn Abd al-Haqq ibn Rahhu (Arabic: حمّو بن عبدالحق بن رحّو) was a Marinid prince who served as shaykh al-ghuzat (chief of the Volunteers of the Faith) in the Nasrid Emirate of Granada during the reigns of Muhammad III (r. 1302–1309) and Nasr (r. 1309–1314).[1]
He unsuccessfully rebelled against the Marinid Sultan Abu al-Rabi Sulayman (r. 1289–1310) in North Africa. Like many dissident princes, he was exiled to Granada to join the "Volunteers of the Faith", a military corps made up of North Africans who fought to defend Muslims in the Iberian Peninsula.[2] Under Muhammad III, he commanded the troops that captured Bedmar from Castile in April 1302, two weeks after the Sultan's accession.[3] When another Marinid prince Uthman ibn Abi al-Ula entered the Nasrid service, he was given command of the Volunteers in Malaga and the western territories, while Hammu ibn al-Haqq kept the command in Granada.[2] He kept the post after Muhammad III was deposed and replaced by his brother Nasr.[4] When a rebellion broke out against Nasr in favor of his nephew Ismail I, Hammu remained loyal while Uthman sided with Ismail.[5] The rebellion was ultimately successful, Nasr abdicated in 1314 while Hammu lost his post and followed Nasr to exile in Guadix.[5][2]
