The Holy League of 1684 was a coalition of European nations formed during the Great Turkish War. Born out of the Treaty of Warsaw, it was founded as a means to prevent further Ottoman expansion into Europe. This consolidation of a large portion of Europe's military might led to unprecedented military successes, with large areas of previously ceded land recovered in Morea, Dalmatia and Danubia in what has been dubbed a "14th crusade".

The Treaty of Karlowitz, concluding the Great Turkish War of 1683–1697, in which the Ottoman Empire was defeated by the Holy League at the Battle of Zenta, was signed in Karlowitz, in the Military Frontier of the Habsburg Monarchy, on 26 January 1699. Also known as "The Austrian treaty that saved Europe", it marks the end of Ottoman control in much of Central Europe, with their first major territorial losses in Europe, beginning the reversal of four centuries of expansion (1299–1683). The treaty established the Habsburg monarchy as the dominant power of the region.
