As Louis Philippe, Duke of Chartres, he distinguished himself commanding troops during the Revolutionary Wars, but broke with the Republic over its decision to execute King Louis XVI. He fled to Switzerland in 1793 after being connected with a plot to restore France's monarchy. His father Louis Philippe II, Duke of Orléans (Philippe Égalité) fell under suspicion and was executed, and Louis Philippe remained in exile for 21 years until the Bourbon Restoration. He was proclaimed king in 1830 after his fifth cousin Charles X was forced to abdicate by the July Revolution.
