 Upon his accession to the throne, Louis Philippe assumed the title of "King of the French" – a title already adopted by Louis XVI in the short-lived Constitution of 1791.Linking the monarchy to a people instead of a territory (as the previous designation "King of France and of Navarre") was aimed at undercutting the legitimist claims of Charles X and his family.By an ordinance he signed on 13 August 1830, the new king defined the manner in which his children, as well as his "beloved" sister, would continue to bear the surname "d'Orléans" and the arms of Orléans, declared that his eldest son, as "Prince Royal" (not "Dauphin"), would bear the title "Duke of Orléans", that the younger sons would continue to have their previous titles, and that his sister and daughters would only be styled "Princesses of Orléans", not "of France".
