He faced first invasion from Alauddin in 1310 and agreed to become tributary of Delhi. After death of Alauddin, he stopped making tributes but then he faced another invasion in 1318, and was forced to pay tribute to Mubarak Shah, son of Alauddin. After end of Khilji dynasty, he again stopped making payments. In 1323, an invasion from Ghiyasuddin Tughlaq ended the Kakatiya dynasty and their territories were annexed into Delhi sultanate.
