Principalities north of the Loire

Outside the dynastic royal domain (centred around Paris) the foremost northern powers were Flanders, Normandy, Anjou, Brittany, Blois-Champagne, and Burgundy.

The northernmost of these was Flanders, whose founder, Baldwin I (Iron-Arm; reigned 862–879), managed not only to abduct the Carolingian king’s daughter and marry her but also to win that king’s approval as count of Ghent. His authority was consolidated under his son Baldwin II (879–918) and grandson Arnulf I (918–965), the latter a violent and ambitious prince who undertook to restore the Flemish church as if he were an emperor. Fertile and precocious in trading activity, Flanders became home to a dense network of prosperous cities and monasteries; monks at Saint-Bertin and Ghent celebrated the dynastic feats of the counts.

In the time of Robert I (the Frisian; 1071–93), efforts were made to systematize the count’s lordship over castles as well as his fiscal rights, but the results fell short of giving the count effective sovereign power. When the foreign-born Charles the Good (1119–27) tried to pacify the county at the expense of lesser knightly families, he was murdered. Stability together with a new and centralized mode of fiscal accountancy was achieved by Thierry of Alsace (1128–68) and his son Philip (1163–91). Toward 1180 Flanders was a major power in northern France.

The duchy of Normandy was created in 911, when the Viking chieftain Rollo (Hrolf) accepted lands around Rouen and Evreux from King Charles III (the Simple). With its pastures, fisheries, and forests, this territory was a rich prize, and Rollo’s successors extended their domination of it aggressively. Early Norman history, however, is more obscure than Flemish, lacking the records that only Christian clerics could write. The acquisitions of the second duke of Normandy, William I (Longsword; 927–942), were threatened when he was murdered by Arnulf I of Flanders in 942. It was only in the reign of his son Richard I (942–996) that something like administrative continuity based on succession to fiscal domains and control of the church was achieved. The dukes (as they then came to be styled) allied with the ascendant duke Hugh Capet had little to lose from the latter’s accession to the kingship in 987; it was at this time that a new Norman aristocracy in ducal control took shape. Under Robert I (the Devil; 1027–35) agrarian and commercial prosperity favoured the multiplication of castellanies and knights, and Duke William II (1035–87; William the Conqueror) had to put down a dangerous rising of Norman barons and castellans in 1047 before proceeding, surely in deliberate consequence, to establish a firmly central control of castles that was without precedent in France. His conquest of England in 1066 made William the most powerful ruler in France. At the same time, knights from lesser elite families in Normandy were establishing territorial lordships in southern Italy.

Norman ducal lordship was crude but effective. Under Henry I (1106–35) a unified exploitation of patronage, castles, and revenues was developed for the kingdom of England and the duchy of Normandy alike. Normandy passed to Henry’s son-in-law Count Geoffrey of Anjou in 1135 and to his grandson Henry II (1150–89), in whose time it became the heartland of an Angevin dynastic empire.

Anjou, in the lower Loire valley, was among the lands delegated to Robert the Strong in 866. In the 10th century a series of vigorous counts established a dynastic patrimony that expanded under the great Fulk III Nerra (987–1040) and his son Geoffrey Martel (1040–60) to include Maine and Touraine. Strategically situated, this principality prospered in its early times of external danger, but it was surrounded by aggressive dynasts; the control of castles and vassalic fidelities were the count’s somewhat precarious means of power.

Brittany, to the west of Anjou and Normandy, was set apart by its strongly Celtic tradition. It achieved identity in the 9th century under the native leader Nomenoë, who seized Nantes and Rennes in defiance of Charles the Bald. His successors, badly battered by the Vikings, were recognized as dukes in the 10th century but were unable to consolidate their power over lesser counts and castellans. With little more than an unenvied independence, the duchy persisted into the 12th century, when a series of succession crises enabled King Henry II of England to subject it to the Plantagenet domains. Only after 1166 were the Bretons to feel the impact of systematic territorial administration.

The area around Blois, to the east of Touraine, had also been entrusted to Robert the Strong and remained in his family’s hands until about 940, when Theobald I (the Old) seized control of it and founded a line of counts of Blois. His successors, notably the fearsome Eudes II (996–1037), annexed the counties of Sancerre (1015) and Champagne (1019–23), thereby creating a principality comparable in strength to Flanders and more threatening to the king, whose patrimonial domains it encircled. A dynastic aggregate lacking natural cohesion, Blois-Champagne achieved its greatest strength under Theobald IV (the Great; Theobald II of Champagne, 1125–52), who was a formidable rival of Kings Louis VI and Louis VII. The main lands were divided under his sons Theobald V (1152–91) and Henry (1152–81), themselves prestigious lords; and the Champagne of Henry the Liberal was among the richest, best organized, and most cultured French lands of its day.

Finally, there was Burgundy, to the south of Champagne (not to be confused with the old kingdom and the later imperial county of Burgundy), which first achieved princely identity under Richard the Justiciar (880–921). Defeating Magyars and Vikings as well as exploiting the rivalries of his neighbours, Richard was regarded (like his near contemporary Arnulf I of Flanders) as virtually a king. Ducal power was contested and diminished thereafter, but it survived as the patrimony of a Capetian family until 1361.

Thus, by the later 12th century, France north of the Loire consisted of several large principalities (some of them associated with the English crown) coexisting with each other and with the king, who struggled to impose his lordship on them.
