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.

Annals of Kings Richard II and Henry IV 1393-1406

The Annals of Kings Richard II and Henry IV offers a vivid contemporary account of one of the most turbulent periods in late medieval England. Covering the reigns of Richard II and Henry IV, the chronicle records royal ceremonies, political conflict, rebellion, war, taxation, religious controversy, executions, popular unrest and remarkable portents. Its pages include a detailed description of Richard II’s coronation, the fall and deposition of the king, Henry IV’s seizure of the throne, the Percy rebellion, the execution of Archbishop Richard Scrope, the campaigns of Owain Glyndŵr, and England’s relations with Scotland, France, Portugal and Scandinavia. Alongside affairs of state, the annalist preserves reports of miracles, eclipses, prophecies, supernatural events and the experiences of ordinary townspeople, clergy, soldiers and travellers. Written from a monastic perspective, the work combines political observation with moral judgement, presenting victories and disasters as evidence of divine favour or punishment. At once a historical record and a reflection of medieval belief, the Annals provides an invaluable window into the challenges, ceremonies and conflicts of England at the turn of the fifteenth century.
