An order, line or right of succession is the line of individuals necessitated to hold a high office when it becomes vacated, such as head of state or an honour such as a title of nobility. This sequence may be regulated through descent or by statute.
The Legitimists (French: Légitimistes) are royalists who adhere to the rights of dynastic succession to the French crown of the descendants of the eldest branch of the Bourbon dynasty, which was overthrown in the 1830 July Revolution. They reject the claim of the July Monarchy of 1830–1848 which placed Louis Philippe, Duke of Orléans, head of the Orléans cadet branch of the Bourbon dynasty, on the throne until he too was dethroned and driven with his family into exile.
Following the movement of Ultra-royalists during the Bourbon Restoration of 1814, Legitimists came to form one of France's three main right-wing factions, which were principally characterized by their counter-revolutionary views. According to historian René Rémond, the other two right-wing factions were the Orléanists and the Bonapartists.
