The Story

Deputy in Morocco

Yusuf ibn Tashfin was appointed by his cousin Abu Bakr ibn Umar to continue the Almoravid war against the Zanata in Morocco. His position strengthened after Abu Bakr returned to the desert, while Yusuf consolidated support among Lamtuna chiefs and expanded his financial and military resources. Through levies from tributaries, purchases of enslaved people from the Sudan, and the acquisition of Christian captives from Spain, he built a more heterogeneous army.

Yusuf changed the character of the Almoravid forces by introducing drums and flags and by moving beyond the older model of a purely nomadic tribal army. Although he continued to acknowledge Abu Bakr's superiority before 1087, his growing authority in the Maghrib marked the movement's gradual shift away from its desert centre. After Abu Bakr's death in 1087, Yusuf's name appeared on Almoravid coins and his authority became explicit.

Conquests in the Maghrib and Spain

Under Yusuf's leadership, Fez was conquered in 1075, followed by Tlemcen and Oran by 1082 and Ceuta in 1083. Control of Ceuta secured the Almoravid position at the Strait of Gibraltar and created the basis for intervention across the water in al-Andalus. The political fragmentation of Muslim Spain and the Christian advance made Almoravid intervention increasingly attractive to Andalusian jurists and rulers.

The fall of Toledo in 1085 prompted Yusuf to cross to Spain. In 1086 he defeated Christian forces at Zallaqa, temporarily checking the reconquista. He returned to Morocco after the victory, crossed again in 1088 to win at Aledo, and in 1090 began the conquest of the Muslim party kingdoms, which was completed by 1094.

Yusuf's authority was expressed through both military action and religious policy. Supported by legal opinions from leading jurists, he accused the Muslim emirs of corruption, negligence, illegal taxation, and collaboration with Christians. His rule also promoted a strict Maliki interpretation of Islam, while the administration increasingly incorporated Andalusian scholars and cultural practices.

Key Points

  • Built an imperial Almoravid army
  • Conquered Fez, Tlemcen, Oran, and Ceuta
  • Defeated Christians at Zallaqa
  • Unified Muslim Spain by 1094
  • Promoted rigorous Maliki rule
