 The Mamluk leadership in Syria, weakened by the losses of the Black Plague, was unable to quell the Bedouin through military expeditions, so they resolved to assassinate the sheikhs of the tribes.The Al Fadl tribe eventually lost favor, while the Bedouin tribes of al-Karak were strengthened by the later Bahri sultans.In Egypt, the Mamluks, particularly during an-Nasir Muhammad's third reign, had a similar relationship with the Bedouin as in Syria.
