The Chagatai Khanate controlled Central Asia, and its leader since the 1280s was Duwa Khan who was second in command of Kaidu. Duwa was active in Afghanistan, and attempted to extend Mongol rule into India. Negudari governor Abdullah, who was a son of Chagatai Khan's great grandson, invaded Punjab with his force in 1292, but their advance guard under Ulghu was defeated and taken prisoner by Alauddin's predecessor Jalaluddin Khalji.
