Chronica Majora. 19 Dec 1235. In the same year, at the advent of our Lord, Robert Fitz-Walter, a baron of illustrious race, and renowned in feats of arms, went the way of all flesh; and in the same year, too, in the flower of his youth, Roger de Sumeric was taken away from amongst men, a man of singular elegance, respectable race, and of remarkable prowess. In this year, too, as a token of the continuation of his regard, the emperor (age 40) sent a camel to the king.

Chronica Majora. 11 Feb 1236. When the nuptial rejoicings were concluded, the [his brother-in-law] king (age 28) left London and went to Merton [Map], where he summoned the nobles to hear a message lately brought from the emperor (age 41), and to discuss the business of the kingdom. For messengers had come direct from the emperor to the king with letters, asking him without delay to send his brother [his brother-in-law] Richard, earl of Cornwall (age 27), whose circumspect skill report had spread far and wide, to make war on the king of the French. He also promised, by way of assistance, to send all the Imperial forces, especially in order to enable the English king (age 28) not only to recover his continental possessions, but also, when they were regained, to extend his former possessions. To this, the king (age 28) and the nobles there assembled, after due deliberation, replied that it would not be safe or prudent to send one so young out of the kingdom and to expose him to the doubtful chances and dangers of war, since he was the only apparent heir of the king and kingdom, and the hopes of all were centred in him next to the king. For the king, although he was married, had no children, and the queen his wife (age 13) was still young, and did not know whether she was fruitful or barren. But if it was agreeable to his excellency the emperor to summon any other brave man he chose, from amongst the nobles of the kingdom, for the purpose, they, the king, and all his friends and subjects, in accordance with his request, would at once render him all the assistance in their power. The messengers, on receiving this reply, returned to inform their lord.

In Apr 1236 [his son] Jordan Hohenstaufen was born to Frederick I King Jerusalem II Holy Roman Emperor (age 41) and [his wife] Isabella Plantagenet Holy Roman Empress (age 22). He a grandson of King John "Lackland" of England.

Chronica Majora. Around 11 Jul 1236. In this year, about the feast of St. Benedict, the emperor (age 41) sent a handsome present to the [his brother-in-law] king of England (age 28), consisting of eighteen valuable horses, and three mules laden with silks and other costly presents. He also sent some valuable horses and other desirable things to [his brother-in-law] Earl Richard (age 27), the king's brother.

Around Sep 1236 [his son] Jordan Hohenstaufen died.

Chronica Majora. Sep 1236. About the same time, the pope, by mandatory letters, strictly forbade the emperor (age 41) to invade Italy; for the latter had, in the summer, called together ail the Imperial forces he could muster, to attack the insolent Italians, and especially the inhabitants of Milan, for that city was a receptacle for all heretics, Paterines, Luciferians, Publicans, Albigenses, and usurers; and it seemed to the emperor to be an ill-advised plan for him to assist the Holy Land by the presence of himself and such a large army of God, and to leave behind him false Christians, worse than any Saracen. He moreover wondered beyond measure that the pope should be in any way favourable to the Milanese, or shoiild seem in any manner to afford them protection, since it became him to be a father to the pious, and a hammer to the wicked. In reverence, however, for such a great father as his holiness the pope, the emperor modestly and prudently replied to him as follows.

In 1237 [his daughter] Agnes Hohenstaufen was born to Frederick I King Jerusalem II Holy Roman Emperor (age 42) and [his wife] Isabella Plantagenet Holy Roman Empress (age 23). She a granddaughter of King John "Lackland" of England.

In 1237 [his daughter] Agnes Hohenstaufen died.

Chronica Majora. 05 Jan 1237. In the year of our Lord 1237 which was the twentieth of the reign of King Henry the Third, he held his court at Christmas, at Winchester, whence he forthwith sent royal warrants throughout all the English territories, ordering all nobles belonging to the kingdom of England, namely, archbishops, bishops, abbats, installed priors, earls, and barons, all to assemble without fail in the octaves of the Epiphany at London, to arrange the royal business and matters concerning the whole kingdom. The nobles on hearing this immediately obeyed the king's summons, and accordingly on the day of St. Hilary, a countless multitude of nobles, namely, the whole community of the kingdom, came to London, and proceeded to the royal palace at Westminster to hear the king's pleasure. When they had all taken their seats, there stood up in the midst of them, one William de Kaele, a clerk and familiar of the king's, a discreet man and well skilled in the laws of the land, who, acting as a sort of mediator between the king and the nobles, disclosed to them the king's pleasure and intentions. "My lord the king," he said, "informs you that, whatever he may have done heretofore, he now and henceforth will, without hesitation, submit himself to the advice of all of you, as his faithful and natural subjects. But those men who have till now, in the management of his affairs, been in charge of his treasury, have rendered him an incorrect account of the moneys received by them, and owing to this the king is now destitute of money, without which any king is indeed destitute; he therefore humbly demands assistance from you in money, on the understanding that the money which may be raised by your good will shall be kept to be expended for the necessary uses of the kingdom, at the discretion of any of you elected for the purpose. "When the assembled nobles heard this speech, they each and all, not expecting anything of this sort, murmured greatly, and "Alter in alterius jactantes lumina vultus". [Each hearer lost in dire amaze, Turned on his neighbour's face his gaze.]

And they said to one another, Fuderunt partum montes: en ridiculus mus. [The labouring mountains shook the earth, And to a paltry mouse gave birth. This is a quote from Aesop's Fable "The Mountain in Labour". It refers to speech acts which promise much but deliver little].

They then replied with indignation that they were oppressed on all sides, so often promising and paying now the twentieth, now the thirtieth, and now the fiftieth part of their property, and they declared that it would be unworthy of them, and injurious to them, to allow a king so easily led awav, who had never repelled or even frightened one of the enemies of the kingdom, even the least of them, and who had never increased his territories but rather lessened them, and placed them under foreign yoke, to extort so much money, so often, and by so many arguments, from his natural subjects, as if they were slaves of the lowest condition, to their injury and for the benefit of foreigners. "When the king heard this, he wished to calm the general discontent, and promised on oath that he would never again provoke or annoy the nobles of the kingdom by injuring them in that way, provided that the thirtieth part of all moveable property in England was granted and paid to him for his present use; because the large sum of money which he had a little while before sent to the emperor (age 42) (as he stated) for the marriage of his [his wife] sister (age 23), and also what he had spent at his own marriage, had in a great degree exhausted his money. To this they openly replied that he, the king, had done all this without the advice of his liege subjects, and they ought not to share the punishment as they were innocent of the crime. They however withdrew to a private place to consult about obeying the king's demand, and supplying his necessities, and to discuss the kind and quantity of assistance which was demanded. As they were withdrawing for this purpose, Gilbert Bassett (age 49) said to the king in the hearing of all. and with less circimispection of speech than he ought, - "My lord king, send some one of your friends to be present at the conference of your barons." He was, when he said this, sitting on one side of the king, with only a few persons between them, and in reply to his speech, Richard Percy (age 67), who had been at the conference of the nobles, and was, not without cause, angry at it, said, "What is it, friend Gilbert, that you said? are we too foreigners, and are we not amongst the number of the king's friends? "And Gilbert felt himself rebuked by this unpleasant and sudden speech. And thus by a multipHcity of arguments the conference was protracted for four days.

On 02 Feb 1237 [his illegitimate sister-in-law] Joan Plantagenet (age 46) died at Abergwyngregyn Bangor.

Chronica Majora. Mar 1237. About the same time, the king's anger was again kindled against the earl of Kent, Hubert de Burgh (age 67), because Richard, earl of Gloucester (age 14), still a boy, under the king's care, secretly married Earl Hubert's (age 67) daughter Margaret (age 15), without his, the king's, permission or connivance. For he had determined (as it was stated) to unite the said youth, the earl of Gloucester, together with his county and all his honours, to a young lady, a near relative of William, bishop elect of Valentia, a native of Provence. The king's anger was, however, at length set at rest by the intercession of a great many people, and on Hubert's declaring that he had not been aware of it, and that it had not been done by him, and on his promising a sum of money to the king. In the same year, by the management of the emperor Frederick (age 42), another senator was created at Rome, in order that, by the united skill and power of two senators, the insolence of the Romans might be checked, and the city be pacified, and governed more safely, and easily ruled by their counsels.

Chronica Majora. Around 15 Apr 1237. About the same time, the emperor Frederick (age 42), finding that the malice of his enemies had recalled him to Germany from his intended expedition, and that, to his disgrace, he was obliged to raise the siege and retire from Milan instituted an inquiry as to who had caused him this obstruction, and finding that the duke of Austria had stirred up internal discord in Germany, and that he was the cause of his being hindered in his purpose, attacked him and deprived him of his lands, honours, and wealth.

Chronica Majora. Before 24 Jun 1237. In the same year, the emperor Frederick (age 42), by special messengers and imperial letters, summoned all the great Christian princes of the world to assemble on the day of St. John the Baptist's nativity, at Vaucouleurs, which is on the confines, or near the confines, of the empire and the French kingdom, there to discuss some difficult matters concerning the empire as well as the kingdom. The king of France, as if entertaining suspicion of this conference, proceeded at the time fixed to the place appointed, attended by a large army, which he had assembled for the purpose, and thus set dreadful and pernicious example to others, inasmuch as he went to discuss matters of peace in the same way as he would to attack his enemies. The [his brother-in-law] king of England (age 29) made reasonable excuses for not coming in person; but sent a peaceful embassy, consisting of some of the chief men of the kingdom; namely, [his brother-in-law] Richard earl of Cornwall (age 28), his brother, with some other nobles, fit to manage a conference, under the guidance of the venerable archbishop of York (age 57) and the bishop of Ely, and other trustworthy persons selected for the purpose. The bishop of Winchester, although selected before all others, absolutely refused to go, and, not without reason, gave the following as the cause for excusing himself: "My lord king," said he "you lately laid a heavy complaint against me before the emperor, telling him that I, with some other nobles, disturbed your kingdom: whether you did this with justice, or unjustly, God knows; but I trust that I have saved my conscience in every respect. But if your words were now placed with confidence in my mouth and in your letters, and should declare that I was a familar and faithful friend of yours; all this would appear as contrary, and he would accuse both you and me of instability; and this would blacken your fame in a great degree. Therefore, because it would be manifestly to your dishonour, I will not go on any account." And in the opinion of many, this reply gave sufficient excuse for him. When all preparations had been made, and they were all ready to set sail on this journey, they were met by letters from the emperor, to say that he could not go to the conference then, as he had purposed; but that what he could not do then, should, by God's favour, be carried into effect on the Nativity of St. John the Baptist in the following year; and thus each and all of them returned without effecting anything. In this year, on the day of the Supper, the bishop of Hereford consecrated the holy unction in the church of St. Albans [Map]. About this time, too, John Scott (deceased), earl of Chester, closed his life about Whitsuntide, having been poisoned by the agency of his wife (age 19), the daughter of Llewellyn (age 65). The life of the bishop of Lincoln (age 69), too, was also attempted by the same means, and he was with difficulty recalled from the gates of death. In the same year, in the week before Whitsuntide, there fell storms of hail which exceeded the size of apples, killing the sheep; and they were followed by continued rain.
