Odo II, Count of Blois

[2] He was the first to unite Blois and Champagne under one authority although his career was spent in endless feudal warfare with his neighbors and suzerains, many of whose territories he tried to annex.

After her death in 1005, and as she had no children, Richard II of Normandy demanded a return of her dowry: half the county of Dreux.

[5] Defeated by Fulk III of Anjou and Herbert I of Maine at the Battle of Pontlevoy in July 1016, he quickly tried to overrun the Touraine.

[3] After the death of his cousin Stephen I in 1019/1020, without heirs he seized Troyes, Meaux and all of Champagne for himself without royal approval.

Due to an alliance between the king and the Emperor Henry II he was forced to relinquish the county of Rheims to the archbishop.
