Treaty of Passarowitz

The Treaty of Passarowitz concluded the Austro-Turkish War of 1716 to 1718, in which the Habsburg monarchy, allied with Venice, fought the Ottoman Empire. Prince Eugene of Savoy won decisive victories for Austria, most notably at Petrovaradin in 1716 and at the capture of Belgrade in 1718, leaving the Ottomans willing to negotiate an end to the conflict.

Signed on 21 July 1718 in the town of Passarowitz, today Pozarevac in Serbia, the treaty registered substantial Austrian gains. Austria acquired Belgrade, northern Serbia, the Banat of Temesvar, and parts of Wallachia and Bosnia. Venice, however, fared poorly, ceding the Morea in the Peloponnese to the Ottomans, though it retained certain holdings along the Adriatic and in the Ionian Islands.

Passarowitz marked the territorial high point of Habsburg expansion into the Balkans during this period and confirmed the Ottoman Empire's strategic retreat in southeastern Europe. The settlement reshaped the frontier between the two empires along the Danube and Sava rivers. Several of these gains, however, proved temporary, as Austria lost Belgrade and northern Serbia back to the Ottomans by the Treaty of Belgrade in 1739.
