The Battle of Slankamen was fought on 19 August 1691, near Slankamen in the Ottoman Sanjak of Syrmia, between the Ottoman Empire, and Habsburg Austrian forces during the Great Turkish War.
The battle saw a Turkish-Transylvanian force led by Emeric Thököly and Mustafa Köprülü suffer an overwhelming defeat by an Imperial army commanded by Ludwig Wilhelm of Baden. The Grand Vizir Mustafa Köprülü was killed by a stray bullet and the Ottoman army routed, leaving behind the war chest and their artillery. The battle was disastrous for the Turks and costly for the Austrians. The victory stabilized the Hungarian front and secured Hungary, Croatia and Transylvania for the Habsburgs.
