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.

Annals of the six Kings of England by Nicholas Trivet
Translation of the Annals of the Six Kings of England by that traces the rise and rule of the Angevin aka Plantagenet dynasty from the mid-12th to early 14th century. Written by the Dominican scholar Nicholas Trivet, the work offers a vivid account of English history from the reign of King Stephen through to the death of King Edward I, blending political narrative with moral reflection. Covering the reigns of six monarchs—from Stephen to Edward I—the chronicle explores royal authority, rebellion, war, and the shifting balance between crown, church, and nobility. Trivet provides detailed insight into defining moments such as baronial conflicts, Anglo-French rivalry, and the consolidation of royal power under Edward I, whose reign he describes with particular immediacy. The Annals combines careful year-by-year reporting with thoughtful interpretation, presenting history not merely as a sequence of events but as a moral and political lesson. Ideal for readers interested in medieval history, kingship, and the origins of the English state, this chronicle remains a valuable and accessible window into the turbulent world of the Plantagenet kings.
