Like his relations, the counts of Vermandois, he remained faithful to the Carolingians against the Capetians. Following the war between his father and Odalric, Archbishop of Reims, over the castle of Coucy, he received the castle to hold it from the archbishop.

In the 970s, in the wars for control of Brittany, he subjugated the county of Rennes and Count Conan I affirmed the rights of his family in the region. Around 977, his father died and he succeeded in the counties his father held at the time of his death.

In 987, Odo supported Charles of Lorraine against Hugh Capet.[2] In June 991, he took Melun.[3] Hugh Capet, Bouchard of Vendome, Richard I of Normandy and Fulk Nerra, assembled against him and retook Melun in late 991.[3]

Near 995, he entered into a war against Fulk, who was already at war with Geoffrey I of Brittany. Odo allied with his brother-in-law William IV of Aquitaine and Baldwin IV of Flanders. Even his old enemy, Richard of Normandy joined in the war on Fulk. In the winter of 995 – 996, they besieged Langeais, however Odo became ill and was taken to the monastery of Marmoutier at Tours where he died on 12 March 996.[4][5]


He married Bertha of Burgundy, daughter of King Conrad of Burgundy and Matilda of France.[6] Their children were:
