Muhammad al-Nasir vs Shajar al-Durr

Muhammad al-Nasir succeeded his father Yaqub al-Mansur as Almohad caliph. He inherited a powerful but overextended empire facing growing Christian pressure in Iberia and internal dissent among Berber tribes.

Muhammad al-Nasir led the Almohad army against a coalition of Christian kingdoms at Las Navas de Tolosa in southern Spain. The Almohad forces were decisively defeated, marking the beginning of the end of Almohad dominance in Iberia and opening the way for the Reconquista.

After the death of her husband As-Salih Ayyub, Shajar al-Durr became the de facto ruler of Egypt. She was proclaimed Sultana with the support of the Mamluk commanders. Her reign marked the first and only time a woman ruled Egypt in the medieval Islamic period.

To legitimize her rule and appease the Ayyubid caliph, Shajar al-Durr married the Mamluk commander Aybak. She abdicated the throne in his favor but retained significant influence. This marriage established the Mamluk Sultanate under Aybak's nominal rule.

Shajar al-Durr ordered the assassination of her husband Sultan Aybak in his bathhouse after he planned to marry another woman. She feared losing her power and influence. This act led to a power struggle among the Mamluks and her own downfall.

After Aybak's murder, Shajar al-Durr was arrested by the Mamluks loyal to Aybak. She was beaten to death by Aybak's concubines or slaves, and her body was thrown into a ditch. Her death ended the brief period of female rule in the Mamluk Sultanate.
