The marriage of Sulla and Caecilia Metella and his political background are analyzed in the article. Their marriage testified to the appearance of the new political faction (Sulla, Metellus Pius, Pompey Rufus), which replaced factio Metellana (it disappeared in the end of 90s BC). Evidently, Sulla wasn’t a Metellan protégé – more probably there was equitable partnership between him and Metelli whose influence weakened by the time.
