Johann Georg Christian Prince of Lobkowicz

Johann Georg Christian, Prince of Lobkowicz (1686–1755), was an Austrian field marshal and a member of the Bohemian noble family, the Lobkowiczs. He established a cadet branch of his family known as the Hořín–Mělník line. Born in Prague to Ferdinand August Leopold, 3rd Prince of Lobkowicz, and Marie Anna Wilhelmine of Baden-Baden, he pursued a military career.

Lobkowicz fought against the French during the War of the Spanish Succession and against the Ottomans in the Austro-Turkish Wars (1716–1718) alongside Prince Eugene of Savoy. By 1717, he commanded his own cuirassier regiment. He became Governor of Sicily in 1732 and was later promoted to field marshal in 1741. During the War of the Austrian Succession (1740–1748), he successfully fought against French and Bavarian forces near Prague but lost the Battle of Velletri in 1744.

Lobkowicz also served as Governor of the Duchy of Milan from 1743 to 1745. In 1745, composer Christoph Willibald Gluck traveled to London, likely with Ferdinand Philipp, a younger cousin of Lobkowicz. Lobkowicz married Countess Henriette of Waldstein-Wartenburg in 1717; they had ten children. Two sons died in battle, while others pursued military or diplomatic careers, including becoming Knights in the Order of the Golden Fleece or bishops.

Lobkowicz was ennobled as a Knight in the Order of the Golden Fleece in 1739 and played significant roles in various conflicts involving Austria during his career.
