Hugh the Great (c. 898 – 16 June 956) was the duke of the Franks and count of Paris. He was the most powerful magnate in France. Son of King Robert I of France, Hugh was Margrave of Neustria. He played an active role in bringing King Louis IV of France back from England in 936. Seeking an alliance with the Holy Roman Emperor Otto the Great, he married Otto's younger sister Hedwig of Saxony in 937. They were the parents of Hugh Capet. Hedwig's sister, Gerberga of Saxony, was Louis' wife. Although he often fought against Louis, he supported the accession of Louis and Gerberga's son, Lothair of France.
