Selim I
Relations with Babur

Babur 's early relations with the Ottomans were poor because Selim I provided Babur's Uzbek rival Ubaydullah Khan with powerful matchlocks and cannons. In 1507, when ordered to accept Selim I as his rightful suzerain, Babur refused and gathered Qizilbash servicemen in order to counter the forces of Ubaydullah Khan during the Battle of Ghazdewan in 1512. In 1513, Selim I reconciled with Babur (fearing that he would join the Safavids), dispatched Ustad Ali Quli and Mustafa Rumi, and many other Ottoman Turks, in order to assist Babur in his conquests; this particular assistance proved to be the basis of future Mughal-Ottoman relations. From them, he also adopted the tactic of using matchlocks and cannons in field (rather than only in sieges), which would give him an important advantage in India.
