Queen Gerberga made an arrangement with her brother-in-law Hugh the Great, Duke of the Franks and Count of Paris, who had been an adversary of Lothair's father. In exchange for supporting Lothair's rule Hugh was given rule over Duchy of Aquitaine and much of the Kingdom of Burgundy as more or less a regent. Lothair inherited a fragmented kingdom, where the great magnates took lands, rights and offices almost without any regard for the authority of the king. Magnates like Hugh the Great and Herbert II, Count of Vermandois were always a veiled threat.
