In 1716, Prince Eugene of Savoy defeated the Turks at Petrovaradin. The Banat and its capital Timişoara was conquered in October 1716. The following year, after the Austrians capturedBelgrade, the Turks wanted peace and in 1718 the Treaty of Passarowitz was signed. The Austrians maintained control over Belgrade and the Treaty of Passarowitz confirmed their gains in 1699, leaving the Turks with control over the south bank of the Danube river. The war led to the loss of Austrian holdings in Italy because of their support in the Balkans. It caused them to send more supplies to the Balkan front, ultimately reducing focus to their Italian territories which were facing aggression from Spain. Even though Eugene of Savoy asked for the troops to be diverted, focus was given to the Ottomans. This ultimately caused the War of the Quadruple Alliance against Spain.
