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.

Chronicle of Jean le Bel Volume 1. And it is to be known that, when the truces were agreed and sealed before Tournai, all the lords and all manner of men struck their camps on both sides, and each returned to his own land. King Philip of France and the barons and lords went to Paris, and there they separated, and each went back to his own country. Among the others, the Duke of Brittany, who had been in the host among the French more prominently than any of the other princes, set out toward his own land and was seized with so great an illness that he passed from this world before he was halfway to his country1. This was a great misfortune, for from it afterward came great wars and destruction of men, towns, and castles, as you shall hear. And so that each may be better informed how all these evils came about, I shall recount a part of it, as I know it and as I have inquired and heard told by those who were where I was not.
Si est à sçavoir que, quant les treves furent acordées et seellées devant Tournay, tous les seigneurs et toutes manieres de gens se deslogerrent d'une part et d'aultre, et rala chascun en sa contrée; le roy Philippe de France et les barons et les seigneurs s'en alerrent à Paris et là se departirent, et rala chascun en son pays. Entre les aultres, le duc de Bretaigne, qui avoit esté en l'ost entre les Françoys plus grossement que nul des aultres princes, s'en ala par devers son pays et luy prist maladie si grande qu'il trespassa de ce siecle, ainchois qu'il fust en my chemin de son pays, de quoy ce fut grand dommage, car grandes guerres et destructions de gens, de villes, de chasteaulx en avindrent puis aprez, si comme vous orrez. Et pour chascun mielx infourmer comment tous ces moulx avindrent, j'en conteray une partie, ainsy que je le sçay el que j'en ay enquis et ouy dire à ceulx qui ont esté où je n'ay mie esté.
