The battle was fought on 20 March 1528 between two rival kings of Hungary John Zápolya and Ferdinand I. The latter's forces under command of Bálint Török and Johann Katzianer, a Styrian mercenary commander defeated John's army; the battle was the second military defeat for John Zápolya during the civil war.
