Godfrey I (died 1002), called the Prisoner or the Captive (le Captif), sometimes the Old (le Vieux), was the count of Bidgau and Methingau from 959 and the count of Verdun from 963 to his death. In 969, he obtained the margravate of Antwerp and Ename. Between 974 and 998, he was also the count of Hainault and Mons.
He appears as the new count of Verdun in 963, though already count of Bidgau and Methingau through inheritance since 959. In 974, he became count of Mons, and Hainault jointly with Arnold, Count of Valenciennes, after the fall of Reginar IV. Charles, Duke of Lower Lorraine, was a supporter of Reginar and defeated Godfrey and Arnold at Mons in 976, where the former was captured.
After his release, he was at the side of the Emperor Otto II fighting Lothair of France at Verdun in 985, but he was again taken captive and held several years. He was released in 987 by Hugh Capet, whose political ally Godfrey's family was: Adalberon, Godfrey's brother, having crowned Hugh and Godfrey being an enemy of Charles of Lower Lorraine, Hugh's Carolingian rival.
In 989, he was made prisoner a third time by Herbert III of Vermandois. He was liberated before 995, when he appears at the synod of Mousson. In 998, he lost his Hainault portion (the county of Mons) to Reginar.
