The Battle of Szina or Seňa took place near Szina in the Kingdom of Hungary (present-day Seňa, in Slovakia). 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.
