During the Bourbon Restoration (1814–1830) and the July Monarchy (1830–1848), the Doctrinals (Doctrinaires) were a group of French royalists who hoped to reconcile the monarchy with the French 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). The Doctrinaires were a centrist, as well as a conservative-liberal group, but at that time, liberal was considered to be the mainstream political left, so the group was considered a centre-left group. During the July Monarchy, they were an intellectual and political group within the Resistance Party. Led by the Duke of Broglie and François Guizot, the Doctrinaires held powerful posts throughout the reign of Louis-Philippe. Broglie (1835–1836) and Guizot (1847–1848) were both Prime Ministers of France, although Guizot and the Doctrinaires dominated the political scenery during the premiership of Marshal Jean-de-Dieu Soult (1840–1847). The Doctrinaires first obtained in 1816 the co-operation of Louis XVIII, who had been frightened by the violence of the Ultra-royalists in the Chambre introuvable of 1815. However, the Ultras quickly came back to government, headed by the comte de Villèle. The Doctrinaires were then in the opposition, although they remained quite close to the government, especially to Decazes who assumed some governmental offices. The Doctrinaires were opposed on their left by republicans and liberals, and on their right by the Ultras. Finally, the Doctrinaires were destroyed by Charles X, the reactionary successor of his brother Louis XVIII. Charles took the ultra prince de Polignac as his minister. This nomination in part caused the 1830 July Revolution, during which the Doctrinaires became absorbed in the Orléanists, from whom they had never been separated on any ground of principle.
