Around 1308, the Delhi Sultanate ruler Alauddin Khalji sent a large army led by his general Malik Kafur to Devagiri, the capital of the Yadava king Ramachandra. A section of the Delhi army, commanded by Alp Khan, invaded Karna's principality in the Yadava kingdom, and captured the Vaghela princess Devaladevi, who later married Alauddin's son Khizr Khan. Another section, commanded by Malik Kafur captured Devagiri after a weak resistance by the defenders. Ramachandra agreed to become a vassal of Alauddin, and later, aided Malik Kafur in the Sultanate's invasions of the southern kingdoms.
