Emperor Shirakawa vs Shajar al-Durr

Shirakawa abdicated the throne but continued to rule from a monastery as a cloistered emperor, creating the Insei system. This allowed retired emperors to wield real political power, bypassing the Fujiwara regents and dominating court politics for decades.

Shirakawa forced his son Horikawa to succeed him, overriding Fujiwara preferences. This conflict solidified the cloistered emperor's control over succession and reduced Fujiwara influence, leading to decades of political tension.

Shirakawa appointed Taira no Masamori as military governor of Ise Province, elevating the Taira clan's status. This move strengthened the imperial court's military capacity and laid the foundation for the Taira's later rise to power.

Shirakawa sponsored the construction and renovation of numerous Buddhist temples, including the Hossho-ji and Ensho-ji. This patronage strengthened the imperial family's religious authority and influenced Heian-period Buddhist art and architecture.

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.
