They were both rather reactionary intent on rolling back the revolution but Louis XVIII. Both were monarchs who seeked to crush those against their will and impose their images as the legitimate rulers. Louis XVIII was more moderate and a consensus builder who often selected centrist oriented ministers to help the French people and shunned violence used against former members of the Bonapartist regime. He also made no attempts to overturn the constitutional monachy and respected elections. Charles X was a brutal autocrat who was extremely reactionary and hoped to restore France to the ancien regime. He selected his fellow ultra royalists as his ministers who did not care about the interests of the French people. Charles X also attempted to override the charter that had create the constitutional monarchy of the Bourbon restoration. Charles was overthrown in the Revolution of 1830 which installed a more liberal king, Louis Phillipe.
The last of these emperors, Marcus Aurelius, was the final emperor of the Pax Romana. His reign was followed by the disastrous reign of his brutal son Commodus (160-192 C.E.). By this time, the Empire was struggling to hold off attacking tribes on the frontiers.
