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.

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.

Peter IV King Aragon Dies John I King Aragon Succeeds

On 6th January 1387 [his father] Peter IV King Aragon (age 67) died. His son John (age 36) succeeded I King Aragon.

On 19th May 1396 King John I of Aragon (age 45) died. His brother [his brother] Martin (age 39) succeeded I King Aragon.

Life Charles VI by a Monk of St Denis [~1420]. [19th May 1396]. Indeed, trustworthy men reported the fate of the king, that, while he was riding through the countryside, it happened by chance that those accompanying his retinue found a hare lying in the woods, which was being pursued by the cries of all. However, the king [King John I of Aragon (age 45)], in order to chase the hare, began to urge his horse toward that direction; but as he pressed hard on the course and hastened without thinking, the horse was driven headlong, and falling to the ground, threw the king down headfirst and mortally wounded him. At this event, all who were riding and those who were following, terrified by the harshness of the incident, turned back, and the courtiers attempted to offer help to the fallen one. But before he could be carried to the nearer village, he expired in their hands. And because the lord patriarch had not yet left the kingdom, he was recalled by the [his wife] queen of Aragon (age 31), performed the royal funeral rites, and delivered the royal body to ecclesiastical burial. Thus, with matters duly completed, the messengers returning to the king of France around the middle of October reported the responses of the kings, asserting that, because the king of Aragon had died without an heir, a great war was already arising between the [his brother] Duke of Montblanc (age 39) and another for the dignity of the sceptre to be obtained1.

Referebant equidem fide digni casum regis, quod, cum per patriam equitaret, accidit casu, ut qui preibant ejus comittatum, leporem in silvis jacentem reperierunt, quem fugientem persequutus est clamor universorum. Rex autem, ut leporem insectaretur, equum ad illas cepit urgere partes; sed cum cursui vehementer instaret, et inconsulte festinaret, equus in preceps agitur, corruensque in terram regem dedit precipitem et letaliter vulneratum. Ad hunc casum universus, qui preibat et qui sequebatur, facti acerbitate perterritus conversus est comitatus, et aulici jacenti opem ferre conati sunt. Sed antequam ad villam viciniorem deferretur, inter manus eorum expiravit. Et quia dominus patriarcha nundum regnum exierat, a regina Arragonie revocatus, regias persolvit exequias, et corpus regium tradidit ecclesiastice sepulture. Sic rebus rite peractis, nuncii ad regem Francie circa medium octobris redeuntes, responsiones regum retulerunt, asserentes quod, quia rex Arragonie sine herede obierat, jam inter ducem Montis Albi et alterum guerra oriebatur maxima pro dignitate sceptrigera obtinenda.
