Abu Abdallah Muhammad VI ibn al-Hasan (Arabic: أبو عبد الله محمد بن الحسن‎) sometimes referred to as “Moulay Muhammad”, was the last Hafsid ruler of Ifriqiya (1573-4). His brother Moulay Ahmad had been driven out of power in 1569 by Uluç Ali and when the Spanish reconquered Tunis Ahmad was unwilling to accept their terms for supporting him, preferring instead to remain in exile in Sicily. Instead, the Spanish invasion force under Don John of Austria installed Moulay Muhammad in his place.
