Count Herbert of Vermandois II

  General Notes:

He inherited the domain of his father and in 907, added to it the Saint de Soissons abbey. His marriage with Hildebrand of France (also known as Liégarde) brought him the County of Meaux. In 918, he was also named Count of Mézerais and of the Véxin. With his cousin Bernard, Count of Beauvais and Senlis, he constituted a powerful group in the west of France, to the north and east of Paris. In 923, he imprisoned King Charles III in Château-Thierry, then in Péronne.

In 922, the Archbishop of Rheims, Seulf, called on Herbert II to reduce some of his vassals who were in rebellion against him. On the death of Seulf, in 925, with the help of King Rudolph, he acquired for his second son Hugh (then five years old) the archbishopric of Rheims, which had a large inheritance in France and Germany. In 926, on the death of Count Roger of Laon, Herbert demanded this County for Eudes, his eldest son. He settled there, initially against the will of King Rudolph and constructed a fortress there. Rudolph yielded to pressure to free king Charles III, whom Herbert still held in prison. In 930, Herbert took the castle of Vitry-en-Perthois at the expense of Boso, the brother of King Rudolph. Rudolph united his army with the army of Hugh, marquis of Neustria, and in 931, they entered Rheims and defeated Hugh, the son of Herbert. Artaud became the new archbishop of Reims. Herbert II then lost, in three years, Vitry, Laon, Château-Thierry, and Soissons. The intervention of his ally, Henry the Fowler, allowed him to restore his domains (except Rheims and Laon) in exchange for his submission to King Rudolph.

Later Herbert allied with Hugh the Great and William Longsword, duke of Normandy against King Louis IV, who allocated the County of Laon to Roger II, the son of Roger I, in 941. Herbert and Hugh the Great took back Rheims and captured Artaud. Hugh, the son of Herbert, was restored as archbishop. Again the mediation of the German King Otto I in Visé, near Liège, in 942 allowed for the normalization of the situation.
