 Qalawun was the last Salihi sultan and following his death in 1290, his son, al-Ashraf Khalil, drew his legitimacy as a Mamluk by emphasizing his lineage from Qalawun, thus inaugurating the Qalawuni period of Bahri rule.Like his two Bahri predecessors, Khalil's main priorities were organization of the sultanate, defeat of the Crusaders and the Mongols, incorporation of Syria into the Mamluk domain and preservation of the import of new mamluks and weaponry.With regards to the latter policy, Baybars had purchased 4,000 "mamluks", Qalawun purchased 6,000–7,000 and by the end of Khalil's reign, there was an estimated total of 10,000 mamluks in the sultanate.
