Ultra-royalist

The Ultra-royalists (French: Ultraroyalistes, also called as Ultras) were a French political group active from 1815 to 1830 under the Bourbon Restoration. The Legitimists, another of the main right-wing families identified in René Rémond's classic opus Les Droites en France, were disparagingly classified with the Ultras after the 1830 July Revolution by the victors, the Orleanists, who deposed the Bourbon dynasty for the more liberal king Louis-Philippe.

Ultraroyalist also refers to "someone who is a very strong supporter of royalism."

The Bourbon Restoration

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). Opposed to the limitation of the sovereign's power under the constitutional monarchy, they hoped to restore the Ancien Régime and annul the rupture created by the French Revolution. Passionately espousing the ruling ideology of the Restoration, the Ultras opposed liberalism, republicanism, and democracy. While Louis XVIII hoped for a moderate restoration of the Ancien Régime, acceptable to the masses who had participated in the Revolution, the Ultras held rigidly to the dream of an 'integral' restoration. Their power was due in part to electoral laws which largely favored them: on one hand, a Chamber of Peers composed of hereditary members, on the other hand, a Chamber of Deputies elected under a heavily restricted census suffrage of approximately 100,000 voters.
