Hugh (1057 – October 18, 1101), called the Great (Latin Hugo Magnus) was the first count of Vermandois from the House of Capet. He is known primarily for taking part in the First Crusade. His nickname Magnus (greater or elder) is probably a bad translation into Latin of a French nickname, le Maisné, meaning "the younger", referring to Hugh as younger brother of King Philip I of France.
Hugh was a younger son of King Henry I of France and Anne of Kiev and younger brother of Philip I. He married Adelaide of Vermandois, the daughter of Herbert IV, Count of Vermandois and Adele of Valois. The couple had 9 children: Matilda, who married Ralph I of Beaugency;Elizabeth, Countess of Leicester (d. 1131); Beatrice (fl. 1144), who married Hugh IV of Gournay; Ralph I, Count of Vermandois (d. 1152); Constance, who married Godfrey de la Ferté-Gaucher; Agnes (living 1125), who married Boniface del Vasto; Henry, Lord of Chaumont en Vexin (d. 1130); Simon (d. 1148); and William (d. c. 1096).
Early 1096 Hugh and Philip began discussing the First Crusade after news of the Council of Clermont reached them in Paris. Although Philip could not participate, as he had been excommunicated, Hugh was said to have been influenced to join the Crusade after an eclipse of the moon on February 11, 1096. Late August 1096 Hugh and a small army left France and travelled via the Alps and Rome to Bari, where he would cross the Adriatic Sea into territory of the Byzantine Empire, unlike most crusaders who travelled over land. His armada was possibly commanded by Arnout II, Count of Aarschot. According to Anna Comnena's chronicle the Alexiad Hugh sent an 'absurd' message to her father, Eastern Roman Emperor Alexius I Comnenus, demanding a proper welcome:
Know, Emperor, that I am the King of Kings, the greatest of all beneath the heavens. It is fitting that I should be met on my arrival and received with the pomp and ceremony appropriate to my noble birth.
In response to this message the emperor sent 'urgent instructions' to his nephew John Komnenos, the doux (governor) of Dyrrhachium, and Nicholas Maurokatakalon, commander of the Byzantine fleet, to look out for Hugh and to inform him immediately when he arrived.
Meanwhile Hugh had reached the coast of Longobardi and dispatched twenty-four envoys to the Doux of Dyrrhachium with the following message: 'Be it known to you, Doux, that our Lord Hugh is almost here. He brings with him from Rome the golden standard of St Peter. Understand, moreover, that he is supreme commander of the Frankish army. See to it then that he is accorded a reception worthy of his rank and yourself prepare to meet him.' Whilst sailing the Adriatic Sea from Bari towards Illyricum, Hugh's fleet was overtaken by a heavy storm and most ships were lost. His own ship was thrown upon the shore near Epirus. When Hugh was found and brought to Dyrrhachium John Komnenos treated him to a banquet and he was allowed to rest. By order of the emperor Hugh was closely escorted by Manuel Boutoumites. Eventually Hugh was given an audience by the emperor, who persuaded him to become his liegeman.
The German historian Hans Eberhard Mayer argued that Alexius was fortunate that the first contingent of the crusader army to arrive in Constantinople, led by Hugh, was very small and easy to control. Alexius 'discreetly but unmistakably' restricted Hugh's freedom of movement 'until he was ready to swear that all territories which had belonged to Byzantium before the Turkish invasions would be restored. Moreover any conquests made to the east [...] would be held as fiefs.'
Anna Comnena recorded a conversation between Hugh and Godfrey of Bouillon, wherein Hugh tried to persuade Godfrey to pledge allegiance to Alexius. Godfrey however refused, saying: 'you left your own country as a ruler [...] with all that wealth and a strong army; now from the heights you've brought yourself to the level of a slave. And then, as if you had won some great success, have you come here to tell me to do the same?' Hugh replied: 'we ought to have stayed in our own countries and kept our hands off other people's [...] but since we've come thus far and need the emperor's protection, no good will come of it unless we obey his orders.'
After the Crusaders had successfully made their way across Seljuk territory and, in 1098, captured Antioch, Hugh was sent back to Constantinople to appeal for reinforcements from Alexius. The emperor was uninterested, however, and Hugh, instead of returning to Antioch to help plan the siege of Jerusalem, went back to France. There he was scorned for not having fulfilled his vow as a Crusader to complete a pilgrimage to Jerusalem, and Pope Paschal II threatened to excommunicate him. He joined the minor Crusade of 1101, but was wounded in battle with the Turks led by Kilij Arslan I at the second battle of Heraclea in September, and died of his wounds in October in Tarsus.
