Louis Antoine, Duke of Angoulême

Louis Antoine of France, Duke of Angoulême (6 August 1775 – 3 June 1844) was the eldest son of Charles X of France and the last person in line to be King of France from 1824 to 1830. He was technically King of France and Navarre for less than 20 minutes before he himself abdicated. He gave up being the King, after his father also did. This occurred in the July Revolution of 1830. He never ruled over the country. After his father's death in 1836 he was called Louis XIX.
