Fulk III of Anjou
Fulk Nerra had a longstanding rivalry with Odo II, Count of Blois. Hugh Capet, the king of France had supported the Angevins against Blois. But king Robert II of France had been married to Bertha, (Odo II's mother) and supported Blois against Anjou. The king opposed Fulk's designs on Touraine and this forced him to pull back to Anjou. When Fulk went to the Holy Land Odo II tried to take advantage. He built three new castles to counter those built by Fulk. When Robert II married again, this time to Constance of Arles, she was Fulk's cousin. Relations between the king and Fulk improved. When Count Hugh of Beauvais, a favorite of King Robert, began speaking against his new wife Constance, Fulk had him killed. This turned the king and the church against Fulk. To ask forgiveness, Fulk took a trip to the Holy Land (he made four total). When he returned he built a new monastery. The king decided to stay with Constance. He and Fulk reconcilled in Rome in 1016. That same year war broke out between Fulk and Odo II of Blois. Fulk allied with Herbert I, Count of Maine, called Wakedog, and they attacked Tours. Odo II came in response and the two met on 6 July 1016. Although he was knocked off his horse, Herbert Wakedog rescued him. Fulk defeated Odo II at the Battle of Pontlevoy.
