Then, having brought Mithridates to terms, Sulla returned to finish the civil war against Marius' followers. After a campaign throughout Italy he seized Rome at the Battle of the Colline Gate in November 82 BC and had himself appointed to the revived office of dictator; but whereas a dictator was traditionally appointed for six months at a time, Sulla's appointment had no term limit. Statues of Marius were destroyed and Marius' body was exhumed and thrown in the Tiber. Cinna was already dead, killed by his own soldiers in a mutiny.
