The Deeds of the Dukes of Normandy

The Gesta Normannorum Ducum [The Deeds of the Dukes of Normandy] is a landmark medieval chronicle tracing the rise and fall of the Norman dynasty from its early roots through the pivotal events surrounding the Norman Conquest of England. Originally penned in Latin by the monk William of Jumièges shortly before 1060 and later expanded at the behest of William the Conqueror, the work chronicles the deeds, politics, battles, and leadership of the Norman dukes, especially William’s own claim to the English throne. The narrative combines earlier historical sources with firsthand information and oral testimony to present an authoritative account of Normandy’s transformation from a Viking settlement into one of medieval Europe’s most powerful realms. William’s history emphasizes the legitimacy, military prowess, and governance of the Norman line, framing their expansion, including the conquest of England, as both divinely sanctioned and noble in purpose. Later chroniclers such as Orderic Vitalis and Robert of Torigni continued the history, extending the coverage into the 12th century, providing broader context on ducal rule and its impact. Today this classic work remains a foundational source for understanding Norman identity, medieval statesmanship, and the historical forces that reshaped England and Western Europe between 800AD and 1100AD.

The Deeds of the Dukes of Normandy. Now this William¹ was the son of Robert of Bellême, born of the daughter of Guy, Count of Ponthieu. This Robert, because of his extreme cruelty, was hated both by the king himself and by many other wise men. When he was at last placed in chains, in which he also died, the most noble King Henry seized his stronghold called Bellême and gave it to Rotrou, Count of Perche, his kinsman². Although the region of Bellême did not belong to the duchy of Normandy but to the kingdom of Franks, King Philip of the Franks had long before granted, or as some say sold, the lordship of that region to his cousin William the Elder, King of the English and Duke of the Normans.

Fuit autem hic Willelmus filius Roberti de Bellismo, natus ex filia Widonis comitis Pontivi. Qui Robertus ob nimiam crudelitatem ipsi regi et cæteris multis sapientibus viris exosus habebatur. Ipso denique in vinculis posito, in quibus et defecit, rex Henricus nobilissimus oppidum ejusdem nomine Bellismum cepit et illud Rotroco comiti Perticenci genere suo dedit. Licet pagus Bellis mensis non ad ducatum Northmanniæ pertineret, sed ad regnum Francorum, dederat tamen dominium ejusdem pagi, vel, ut quidam dicunt, vendiderat dudum Philippus rex Francorum cognato suo Willelmo seniori regi Anglorum et duci Northmannorum.
