 In 1291, Khalil captured Acre, the last major Crusader fortress in Palestine and thus Mamluk rule extended across the entirety of Syria.Khalil's death in 1293 led to period of factional struggle, with Khalil's prepubescent brother, an-Nasir Muhammad, being overthrown the following year by a Mongol mamluk of Qalawun, al-Adil Kitbugha, who in turn was succeeded by a Greek mamluk of Qalawun, Husam ad-Din Lajin.In a bid to consolidate his control, Lajin attempted to redistribute "iqtaʿat" to his supporters.
