Odo I (also spelled Eudes) (c. 950 – 12 March 996), Count of Blois, Chartres, Reims, Provins, Châteaudun, and Omois, was the son of Theobald I of Blois and Luitgard, daughter of Herbert II of Vermandois. He received the title of count palatine, which was traditional in his family, from King Lothair of West Francia.
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.In June 991, he took Melun. Hugh Capet, Bouchard of Vendome, Richard I of Normandy and Fulk Nerra, assembled against him and retook Melun in late 991.
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.
He married (c. 983) Bertha of Burgundy, daughter of King Conrad of Burgundy and Matilda of France.Their children were:
Hugh Capet was the King of the Franks from 987 to 996. He is the founder and first king from the House of Capet. The son of the powerful duke Hugh the Great and his wife Hedwige of Saxony, he was elected as the successor of the last Carolingian king, Louis V. Hugh was descended from Charlemagne's sons Louis the Pious and Pepin of Italy through his mother and paternal grandmother, respectively, and was also a nephew of Otto the Great.
Charles III, called the Simple or the Straightforward, was the king of West Francia from 898 until 922 and the king of Lotharingia from 911 until 919–923. He was a member of the Carolingian dynasty.
The Château de Langeais is a 15th century Flamboyant Gothic castle in Indre-et-Loire, France, built on a promontory created by the small valley of the Roumer River at the opening to the Loire Valley. Founded in 992 by Fulk Nerra, Count of Anjou, the castle was soon attacked by Odo I, Count of Blois. After the unsuccessful attack, the now-ruined stone keep was built; it is one of the earliest datable stone examples of a keep. Between 994 and 996 the castle was besieged unsuccessfully twice more. During the conflict between the counts of Anjou and Blois, the castle changed hands several times, and in 1038 Fulk captured the castle again.
Robert I, was the elected King of West Francia from 922 to 923. Before his election to the throne he was Count of Poitiers, Count of Paris and Marquis of Neustria and Orléans. He succeeded the overthrown Carolingian king Charles the Simple, who in 898 had succeeded Robert's brother, king Odo.
Hugh the Great was the duke of the Franks and count of Paris.
Louis V, also known as Louis the Do-Nothing, was a king of West Francia from 979 to his early death in 987. During his reign, the nobility essentially ruled the country. Dying childless, Louis V was the last Carolingian monarch in West Francia.
Theobald the Great (1090–1152) was count of Blois and of Chartres as Theobald IV from 1102 and was count of Champagne and of Brie as Theobald II from 1125. Theobald held Auxerre, Maligny, Ervy, Troyes, and Châteauvillain as fiefs from Duke Odo II of Burgundy.
William IV, called Fierebras or Fierebrace, was the Duke of Aquitaine and Count of Poitou from 963 to his retirement in 990.
Fulk III, the Black, was an early Count of Anjou celebrated as one of the first great builders of medieval castles. It is estimated Fulk constructed approximately 100 castles, along with abbeys throughout the Loire Valley in what is now France. He fought successive wars with neighbors in Brittany, Blois, Poitou and Aquitaine and made four pilgrimages to Jerusalem during the course of his life. He had two wives and three children.
Fulk II of Anjou, called le Bon was Count of Anjou from 942 to his death.
Conan I nicknamed Le Tort was the Duke of Brittany from 990 to his death.
Herbert II, Count of Vermandois, Count of Meaux, and Count of Soissons. He was the first to exercise power over the territory that became the province of Champagne.
Theobald I (913–975), called the Trickster, was the first count of Blois, Chartres, and Châteaudun as well as count of Tours.
Herbert I, called Wakedog, was the count of Maine from 1017 until his death. He had a turbulent career with an early victory that may have contributed to his later decline.
Bertha of Burgundy was queen of the Franks as the second wife of King Robert II.
Theobald II, Count of Blois was the eldest son and heir of Odo I, Count of Blois, and Bertha of Burgundy.
The Robertians are the proposed Frankish family which was ancestral to the Capetian dynasty, and thus to the royal families of France and of many other countries. The Capetians appear first in the records as powerful nobles serving under the Carolingian dynasty in West Francia, which later became France. As their power increased, they came into conflict with the older royal family and attained the crown several times before the eventual start of the continuous rule of the descendants of Hugh Capet.
Bourgueil Abbey was a Benedictine monastery located at Bourgueil, historically in Anjou, currently in Indre-et-Loire and the diocese of Angers. The founder was Emma of Blois, daughter of Theobald I of Blois, and by her marriage, duchess of Aquitaine.
Henry I was King of the Franks from 1031 to 1060. The royal demesne of France reached its smallest size during his reign, and for this reason he is often seen as emblematic of the weakness of the early Capetians. This is not entirely agreed upon, however, as other historians regard him as a strong but realistic king, who was forced to conduct a policy mindful of the limitations of the French monarchy.
Emma of Blois was Duchess consort of Aquitaine by marriage to William IV, Duke of Aquitaine. She ruled Aquitaine as regent for her son, William V, Duke of Aquitaine, from 996 until 1004.
