Battle of Zenta: a major engagement in the Great Turkish War (1683–1699) and one of the most decisive defeats in Ottoman history.

The Battle of Zenta, also known as the Battle of Senta, took place on 11 September 1697 near Zenta, in the Kingdom of Hungary, then under Ottoman occupation. It was a decisive engagement of the Great Turkish War, fought between the forces of the Ottoman Empire and the Holy League. The battle resulted in a significant Ottoman defeat against a numerically inferior Habsburg force acting on behalf of Leopold I, Holy Roman Emperor.

The Great Turkish War or The Last Crusade, also called in Ottoman sources The Disaster Years, was a series of conflicts between the Ottoman Empire and the Holy League consisting of the Holy Roman Empire, Poland-Lithuania, Venice, Russia, and the Kingdom of Hungary. Intensive fighting began in 1683 and ended with the signing of the Treaty of Karlowitz in 1699. The war was a resounding defeat for the Ottoman Empire, which for the first time lost substantial territory, in Hungary and the Polish–Lithuanian Commonwealth, as well as in part of the western Balkans. The war was significant also for being the first instance of Russia joining an alliance with Western Europe. Historians have labeled the war as the Fourteenth Crusade launched against the Turks by the papacy.

The Ottoman Empire, also called the Turkish Empire, was an imperial realm that controlled much of Southeast Europe, West Asia, and North Africa from the 14th to early 20th centuries; it also controlled parts of southeastern Central Europe, between the early 16th and early 18th centuries.
