Muhammad IV of Granada

Muhammad IV (14 April 1315 – 25 August 1333) was the ruler of the Emirate of Granada on the Iberian Peninsula from 1325 to 1333. He was the sixth sultan of the Nasrid dynasty, succeeding to the throne at ten years old when his father, Ismail I (r. 1314–1325), was assassinated. The initial years of his reign were marked by conflict among his ministers, who vied for control of the young sultan's government. He requested help from Abu Said Uthman II of the Marinid Sultanate in Morocco and gave him territories, including Ronda, Marbella, and Algeciras, probably in exchange for Marinid troops. He secured a treaty with Castile on 19 February 1331, but Castile soon broke the treaty by stopping food exports to Granada as had been agreed. In September 1332, Muhammad sailed to Marinid court at Fez to request help. The troops besieged the Castilians at Gibraltar: the town surrendered in June 1333 but was in turn besieged by Alfonso XI. This resulted in a stalemate that ended with a truce that lifted the siege of Gibraltar and restored the 1331 treaty.
