Why did the Mongols fail to conquer Egypt?

The Mongols failed to conquer Egypt primarily due to their overextended supply lines and the logistical challenges of maintaining a prolonged campaign in such a distant region. Additionally, the Mamluks, a formidable military class in Egypt, effectively resisted Mongol advances, notably defeating them at the Battle of Ain Jalut in 1260. This loss marked a significant turning point, halting Mongol expansion into North Africa and solidifying Mamluk power in the region. Furthermore, the Mongol Empire was also facing internal strife and division, which weakened their military focus and resources.
