Prince Eugene Francis of Savoy-Carignano, (18 October 1663 – 21 April 1736) better known as Prince Eugene, was a field marshal in the army of the Holy Roman Empire and of the Austrian Habsburg dynasty during the 17th and 18th centuries. He was one of the most successful military commanders of his time, and rose to the highest offices of state at the Imperial court in Vienna.
Born in Paris, Eugene was brought up in the court of King Louis XIV of France. Based on the custom that the youngest sons of noble families were destined for the priesthood, the Prince was initially prepared for a clerical career, but by the age of 19, he had determined on a military career. Based on his poor physique and bearing, and perhaps due to a scandal involving his mother Olympe, he was rejected by Louis for service in the French army. Eugene moved to Austria and transferred his loyalty to the Holy Roman Empire.
In a career spanning six decades, Eugene served three Holy Roman Emperors: Leopold I, Joseph I, and Charles VI. His first battle experiences were fought against the Ottomans at the Siege of Vienna in 1683 and the subsequent War of the Holy League, before serving in the Nine Years' War, in which he fought 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 the Siege of Belgrade in 1717.
