n. (plural of doctrinaire English)
Wikipedia
The Doctrinals was the name given during the Bourbon Restoration (1814–1830) to the group of French Royalists who hoped to reconcile the Monarchy with the Revolution, and power with liberty. Headed by Royer-Collard, these liberal royalists were in favor of a constitutional monarchy but with a heavily restricted census suffrage — Louis XVIII, who had been restored to the throne, had granted a Charter to the French with a Chamber of Peers and a Chamber of deputies elected under tight electoral laws (only around 100,000 Frenchmen had at the time the right to vote).
