The Peace of Vasvár was a treaty between the Habsburg Monarchy and the Ottoman Empire which followed the Battle of Saint Gotthard of 1 August 1664 (near Mogersdorf, Burgenland), and concluded the Austro-Turkish War (1663–64). It held for about 20 years, until 1683, during which border skirmishing escalated to a full-scale war and culminated with the Ottoman's siege of Vienna for the second time.
