Hugh Capet
The unity of Western Franks against Otto II had the consequence of placing the dynasty of Robertians in a prominent place in the person of Hugh Capet, whose contemporaries attested that he faithfully served king Lothair. The fight with the Emperor strengthened the power of Hugh Capet, which was shown in 980 when he captured Montreuil-sur-Mer from Arnulf II, Count of Flanders.
