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.

Yet he made peace with the king of Spain, receiving a duchy for the term of his life, and a large sum of gold for his outlay, and giving his daughter [aged 15] in marriage to the [her husband] king's eldest son [aged 8]; and so he returned to England1.

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.

Thomas Mowbray Duel

Froissart Book 4 Chapter 95. 16th September 1398. Not long after this, the king of England [aged 31] summoned a large council of the great nobles and prelates at Eltham [Map]. On their arrival, he placed his two uncles of [her father] Lancaster [aged 58] and York [aged 57] beside him, with the earls of Northumberland [aged 56], Salisbury [aged 48] and Huntingdon [aged 46]. The earl of Derby [aged 31] and the earl marshal [aged 30] were sent for, and put into separate chambers, for it had been ordered they were not to meet. The king showed he wished to mediate between them, notwithstanding their words had been very displeasing to him, and ought not to be lightly pardoned. He required therefore that they should submit themselves to his decision; and to this end sent the constable of England, with four great barons, to oblige them to promise punctually to obey it. The constable and the lords waited on the two earls, and explained the king's intentions. They both bound themselves, in their presence, to abide by whatever sentence the king should give. They having reported this, the king said, "Well then, I order that the earl marshal, for having caused trouble in this kingdom, by uttering words which he could not prove otherwise than by common report, be banished the realm: he may seek any other land he pleases to dwell in, but he must give over all hope of returning hither, as I banish him for life. I also order, that the earl of Derby, our cousin, for having angered us, and because he has been, in some measure, the cause of the earl marshal's crime and punishment, prepare to leave the kingdom within fifteen days, and be banished hence for the term of ten years, without daring to return unless recalled by us; but we shall reserve to ourself the power of abridging this term in part or altogether." The sentence was satisfactory to the lords present, who said: "The earl of Derby may readily go two or three years and amuse himself in foreign parts, for he is young enough; and, although he has already travelled to Prussia, the Holy Sepulchre, Cairo and Saint Catherine's1, he will find other places to visit. He has two sisters, queens of Castillo [aged 25] and of Portugal [aged 38], and may cheerfully pass his time with them. The lords, knights and squires of those countries, will make him welcome, for at this moment all warfare is at an end. On his arrival in Castille, as he is very active, he may put them in motion, and lead them against the infidels of Granada, which will employ his time better than remaining idle in England. Or he may go to Hainault, where his cousin, and brother in arms, the count d'Ostrevant, will be happily to see him, and gladly entertain him, that he may assist him in his war against the Frieslanders. If he go to Hainault, lie can have frequent intelligence from his own country and children. He therefore cannot fail of doing well, whithersoever he goes; and the king may speedily recall him, through means of the good friends he will leave behind, for he is the finest feather in his cap; and he must not therefore suffer him to be too long absent, if he wish to gain the love of his subjects. The earl marshal has had hard treatment, for he is banished without hope of ever being recalled; but, to say the truth, he has deserved it, for all this mischief has been caused by him and his foolish talking: he must therefore pay for it." Thus conversed many English knights with each other, the day the king passed sentence on the earl of Derby and the earl marshal.

Following their return to England in 1440 William was witness to major events. Twice in his chronicle he uses the first person: 1. when writing about the murder of Thomas, 7th Baron Scales, in 1460, he writes '… and I saw him lying naked in the cemetery near the porch of the church of St. Mary Overie in Southwark …' and 2. describing King Edward IV's entry into London in 1461 he writes '… proclaimed that all the people themselves were to recognize and acknowledge Edward as king. I was present and heard this, and immediately went down with them into the city'. William’s Chronicle is rich in detail.

A canon regular of the Augustinian Guisborough Priory, Yorkshire, formerly known as The Chronicle of Walter of Hemingburgh, describes the period from 1066 to 1346. Before 1274 the Chronicle is based on other works. Thereafter, the Chronicle is original, and a remarkable source for the events of the time. This book provides a translation of the Chronicle from that date. The Latin source for our translation is the 1849 work edited by Hans Claude Hamilton. Hamilton, in his preface, says: 'In the present work we behold perhaps one of the finest samples of our early chronicles, both as regards the value of the events recorded, and the correctness with which they are detailed; Nor will the pleasing style of composition be lightly passed over by those capable of seeing reflected from it the tokens of a vigorous and cultivated mind, and a favourable specimen of the learning and taste of the age in which it was framed.'

About this, and, moreover, about the coming of your ambassadors, who should come to join themselves with those whom the king my son should send, to see and determine upon the damage and mischief which those who are injured have received of their own goods, f send to you the said John de Samora, who will speak of some things that he will have to say to you from me, and of others which have been already confirmed in my name, which he will tell you. Wherefore, dearest and best-beloved brother and lord, I request you that it would please you to give faith and credence to the things that he will say to you on my part in this matter.

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.
