Hugh of Vermandois became Archbishop of Reims in 925, at only five years old. It was part of a rebellion by his father, Hugh II of Vermandois. Hugh II joined with Robert, Count of Paris, and father of Hugh Capet, in a rebellion against their king, Rudolph of France. They were supported by Otto I. When the rebellion failed in 931, the previous Archbishop was reinstated. The Archbishop of Reims was one of the most influential seats. It crowned the King of the Franks, and would soon ally with the Capets.
