In a career spanning six decades, Eugene served three Holy Roman emperors: Leopold I, Joseph I, and Charles VI. He first saw action against the Ottoman Turks at the Siege of Vienna in 1683 and the subsequent War of the Holy League, before serving in the Nine Years' War, fighting alongside his cousin, the Duke of Savoy. The Prince's fame was secured with his decisive victory against the Ottomans at the Battle of Zenta in 1697, earning him Europe-wide fame. Eugene enhanced his standing during the War of the Spanish Succession, where his partnership with the Duke of Marlborough secured victories against the French on the fields of Blenheim (1704), Oudenarde (1708), and Malplaquet (1709); he gained further success in the war as Imperial commander in northern Italy, most notably at the Battle of Turin (1706). Renewed hostilities against the Ottomans in the Austro-Turkish War consolidated his reputation, with victories at the battles of Petrovaradin (1716), and the decisive encounter at Belgrade (1717).
