Louis XVIII's restoration to the throne in 1814 was effected largely through the support of Napoleon's former foreign minister, Talleyrand, who convinced the victorious Allied Powers of the desirability of a Bourbon Restoration. The Allies had initially split on the best candidate for the throne: Britain favoured the Bourbons, the Austrians considered a regency for Napoleon's son, François Bonaparte, and the Russians were open to either the duc d'Orléans, Louis Philippe, or Jean-Baptiste Bernadotte, Napoleon's former Marshal, who was heir-presumptive to the Swedish throne. Napoleon was offered to keep the throne in February 1814, on the condition that France return to its 1792 frontiers, but he refused. The feasibility of the Restoration was in doubt, but the allure of peace to a war-weary French public, and demonstrations of support for the Bourbons in Paris, Bordeaux, Marseille, and Lyons, helped reassure the Allies.
