Johann Georg Christian, Prince of Lobkowicz

Johann Georg Christian, Prince of Lobkowicz (German: Johann Georg Christian, Fürst von Lobkowitz, Czech: Jan Jiří Kristián z Lobkovic; 10 August 1686 – 4 October 1755), was an Austrian field marshal.

He was born in Prague to Ferdinand August Leopold, 3rd Prince of Lobkowicz and Duke of Sagan, and his second wife, Marie Anna Wilhelmine of Baden-Baden and Hochberg.

Subsequently, he became the commander-in-chief of the Habsburg forces in Italy, but lost the Battle of Velletri (1744) against the army of King Charles III of Spain.

In 1745 composer Christoph Willibald Gluck accepted an invitation to become house composer at London's King's Theatre, travelling to England, possibly in the company of Georg Christian but more likely with his younger cousin, Ferdinand Philipp, 6th Prince Lobkowicz.

Two of their sons were killed in battle; two other sons, Joseph Maria Karl and August Joseph Anton, served in the Austrian military and diplomatic corps and became Knights in the Order of the Golden Fleece and one, Ferdinand Maria of Lobkowicz, became bishop of Ghent.
