What is the reason for such a triumphant return of Napoleon?

Napoleon owes such a triumphant return to the inept policy of King Louis the Eighteenth, the intrigue of the court and the disunity of the victors of the Emperor of France. Discontent and fear of the peasantry that the old order may return, that the land will again be taken away and returned to the aristocracy. The persecution of the Bonapartists was also one of the reasons for the triumphant return. Having landed in Cannes on March 1, 1815, Bonaparte traveled to Paris in 19 days. Along the way, he took Lyons and Grenoble without a fight, joined by Marshal Ney and the soldiers sent to capture him. The soldiers remembered the glorious days of the Empire and the victory of Napoleon.
