The History of William Marshal, Earl of Chepstow and Pembroke, Regent of England. Book 1 of 2, Lines 1-10152.

The History of William Marshal was commissioned by his son shortly after William’s death in 1219 to celebrate the Marshal’s remarkable life; it is an authentic, contemporary voice. The manuscript was discovered in 1861 by French historian Paul Meyer. Meyer published the manuscript in its original Anglo-French in 1891 in two books. This book is a line by line translation of the first of Meyer’s books; lines 1-10152. Book 1 of the History begins in 1139 and ends in 1194. It describes the events of the Anarchy, the role of William’s father John, John’s marriages, William’s childhood, his role as a hostage at the siege of Newbury, his injury and imprisonment in Poitou where he met Eleanor of Aquitaine and his life as a knight errant. It continues with the accusation against him of an improper relationship with Margaret, wife of Henry the Young King, his exile, and return, the death of Henry the Young King, the rebellion of Richard, the future King Richard I, war with France, the death of King Henry II, and the capture of King Richard, and the rebellion of John, the future King John. It ends with the release of King Richard and the death of John Marshal.

Chronicle of Abbot Ralph of Coggeshall

The Chronicle of Abbot Ralph of Coggeshall (Chronicon Anglicanum) is an indispensable medieval history that brings to life centuries of English and European affairs through the eyes of a learned Cistercian monk. Ralph of Coggeshall, abbot of the Abbey of Coggeshall in Essex in the early 13th century, continued and expanded his community’s chronicle, documenting events from the Norman Conquest of 1066 into the tumultuous reign of King Henry III. Blending eyewitness testimony, careful compilation, and the monastic commitment to record-keeping, this chronicle offers a rare narrative of political intrigue, royal power struggles, and social upheaval in England and beyond. Ralph’s work captures the reigns of pivotal figures such as Richard I and King John, providing invaluable insights into their characters, decisions, and the forces that shaped medieval rule. More than a simple annal, Chronicon Anglicanum conveys the texture of medieval life and governance, making it a rich source for scholars and readers fascinated by English history, monastic authorship, and the shaping of the medieval world.

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.
