Marcus Aurelius ended the period of the "[[Five Good Emperors]]" by permitting his incompetent son Commodus to succeed him.  There followed anarchy, called the [[Crisis of the Third Century]].  The Praetorian Guard publicly auctioned the throne; the winner, [[Didius Julianus]], reigned for under a year before [[Septimus Severus]] deposed and executed him.  However, he could not prevent the empire from sliding into chaos.
