The Ultra-royalists (ultraroyalistes, collectively Ultras) were a French political faction from 1815 to 1830 under the Bourbon Restoration. An Ultra was usually a member of the nobility of high society who strongly supported Roman Catholicism as the state and only legal religion of France, the Bourbon monarchy, traditional hierarchy between classes and census suffrage against popular will and the interests of the bourgeoisie and their liberal and democratic tendencies. The Legitimists, another of the main right-wing families identified in René Rémond's Les Droites en France, were disparagingly classified with the Ultras after the 1830 July Revolution by the victors, the Orléanists, who deposed the Bourbon dynasty for the more liberal king Louis Philippe. Second White Terror Following the return of Louis XVIII to power in 1815, people suspected of having ties with the governments of the French Revolution or of Napoleon suffered arrest. Several hundred were killed by angry mobs or executed after a quick trial at a drum head court-martial. The episodes happened primarily in the south of France. Historian John Baptist Wolf argues Ultra-royalist—many of whom had just returned from exile—were staging a counter-revolution against the French Revolution and also against Napoleon's revolution. Throughout the Midi — in Provence, Avignon, Languedoc, and many other places — the White Terror raged with unrelenting ferocity. The royalists found in the willingness of the French to desert the king fresh proof of their theory that the nation was honeycombed with traitors, and used every means to seek out and destroy their enemies. The government was powerless or unwilling to intervene. Inaugurating the Bourbon Restoration (1814–1830), a strongly restricted census suffrage elected to the Chamber of Deputies an Ultra-royalist majority (la Chambre introuvable) in 1815–1816 and again from 1824 to 1827. Known to be "more royalist than the king" (plus royalistes que le roi), the Ultras were the dominant political faction under Louis XVIII (1815–1824) and Charles X (1824–1830).
