Overview
Prince Charles Alexander Emanuel of Lorraine (; ; 12 December 1712 in Lunéville – 4 July 1780 in Tervuren) was a Lorraine-born Austrian general and soldier, field marshal of the Imperial Army, and governor of the Austrian Netherlands.
Early life
Charles was the son of Leopold, Duke of Lorraine, and Élisabeth Charlotte d'Orléans. When his elder brother Francis III, Duke of Lorraine, married the Archduchess Maria Theresa, daughter of Emperor Charles VI, Charles Alexander entered the Imperial service in 1737.
When his brother Francis traded the duchy to the ex-Polish king Stanisław Leszczyński in exchange for the Grand Duchy of Tuscany as one of the terms ending the War of the Polish Succession in November 1738, the ducal title to Lorraine and Bar passed beyond Charles to King Louis XV of France upon Leszczynski's death in 1766, though Francis and his successors retained the right to style themselves as dukes of Lorraine and Bar.
