Louis-Philippe, duc de Chartres and later duc d'Orléans, was the son of Louis-Philippe-Joseph, duc d'Orléans [1747-1793], also known as Philippe Égalité. Louis-Philippe-Joseph was the great-great-grandson of Philippe I, duc d'Orléans [1640-1701], younger brother of Louis XIV, and the great-grandson of Philippe II, duc d'Orléans [1674-1703], who as regent for Louis XV endeavored to secure his own secession over that of Philip V of Spain. Despite his royal blood, Louis-Philippe-Joseph supported the democracy movement of the underpriviledged Third Estate and was considered a hero by the revolutionaries; after the fall of the monarchy in August 1792, he renounced his noble title and accepted the name Philippe Égalité. He was elected to the National Convention, and voted for the execution of Louis XVI. Nonetheless, Égalité himself was sent to the guillotine in 1793, accused of conspiring with his son, the future King, and Austrian accomplices. Louis-Philippe was proclaimed King of the French after the overthrow of Charles X in 1830; his reign is known as the July monarchy. Charles X descended from the "legitimate" line of Bourbon kings, while Louise-Phillipe was of the collateral Orléans line of the house of Bourbon. Louis-Philippe was married to Marie- Amélie of the Two Sicilies [1782-1850], daughter of Ferdinand I, King of Naples. Louise-Phillipe himself was overthrown by the revolution of 1848, when he abdicated and fled to England; he died in 1850. [Compiled from sources and references recorded on CMS]
