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.

Adam Murimuth's Continuation and Robert of Avesbury’s 'The Wonderful Deeds of King Edward III'
This volume brings together two of the most important contemporary chronicles for the reign of Edward III and the opening phases of the Hundred Years’ War. Written in Latin by English clerical observers, these texts provide a vivid and authoritative window into the political, diplomatic, and military history of fourteenth-century England and its continental ambitions. Adam Murimuth Continuatio's Chronicarum continues an earlier chronicle into the mid-fourteenth century, offering concise but valuable notices on royal policy, foreign relations, and ecclesiastical affairs. Its annalistic structure makes it especially useful for establishing chronology and tracing the development of events year by year. Complementing it, Robert of Avesbury’s De gestis mirabilibus regis Edwardi tertii is a rich documentary chronicle preserving letters, treaties, and official records alongside narrative passages. It is an indispensable source for understanding Edward III’s claim to the French crown, the conduct of war, and the mechanisms of medieval diplomacy. Together, these works offer scholars, students, and enthusiasts a reliable and unembellished account of a transformative period in English and European history. Essential for anyone interested in medieval chronicles, the Hundred Years’ War, or the reign of Edward III.
