Al-Ashraf Khalil vs Marwan II

Al-Ashraf Khalil succeeded his father Qalawun as Sultan of Egypt. He was the second ruler of the Qalawunid dynasty. His accession was contested by some Mamluk factions, but he quickly consolidated power.

Al-Ashraf Khalil led the Mamluk siege of Acre, the last major Crusader stronghold in the Levant. After a six-week siege, the city fell on May 18, 1291. The capture of Acre ended the Crusader presence in the Holy Land.

Following the fall of Acre, Al-Ashraf Khalil's forces captured the remaining Crusader coastal cities of Tyre, Sidon, and Beirut without significant resistance. These conquests completed the Mamluk reconquest of the Levant and eliminated all Crusader footholds.

Al-Ashraf Khalil was assassinated by a group of Mamluk emirs while hunting near Cairo. His death was likely due to internal power struggles. He was succeeded by his young brother An-Nasir Muhammad, beginning a period of instability.

Marwan II became the last Umayyad caliph after a period of civil war and succession disputes. He was a military commander who seized power amid the weakening of the dynasty.

Marwan II's army was decisively defeated by the Abbasid forces at the Battle of the Zab in Iraq. This battle ended Umayyad rule and led to the establishment of the Abbasid Caliphate.

After the Battle of the Zab, Marwan II fled to Egypt where he was captured and killed by Abbasid forces. His death marked the end of the Umayyad Caliphate, though a surviving prince founded a dynasty in Spain.
