Prince Eugene of Savoy (18 October 1663 – 21 April 1736), was one of the most successful military commanders in modern European history, rising to the highest offices of state at the Imperial court in Vienna.

Spanning six decades, Eugene served three Habsburg 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. However, the Prince's fame was secured with his decisive victory against the Ottomans at the Battle of Zenta in 1697, earning him European-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).

Throughout the late 1720s Eugene's influence and skilful diplomacy managed to secure the Emperor powerful allies in his dynastic struggles with the Bourbon powers. Although opinions differ as to his character there is no dispute over his great achievements: he helped to save the Habsburg Empire from French conquest; he broke the westward thrust of the Ottomans, liberating central Europe after a century and a half of Turkish occupation; and he was one of the great patrons of the arts whose building legacy can still be seen in Vienna today.
