The period of chivalric enterprises in England had gone by, and that of humiliation and decay was commencing. The reign, however, of John Lackland, the most cowardly and treacherous of the sovereigns who have sat on the throne of England, is one of the most important epochs in history, for from that time dates the active part played by the nation in its own affairs—the time of Magna Charta, the germ and foundation of all English liberty.

Magna Charta

John was well known by the people whom he aspired to govern, and was universally detested. Scarcely had the rumor of the death of King Richard spread through France, when all the nobility of Brittany, Touraine, Anjou, and Maine declared themselves in favor of Prince Arthur, son of Geoffrey Plantagenet and of Constance of Brittany, born seven months after his father's death, whom Richard had repeatedly nominated as his successor. Under the influence of Eleanor, Aquitaine and Poitou recognized John as their liege-lord: he was in Normandy, and caused himself to be proclaimed at Rouen on the 25th of April. He had already sent the Archbishop of Canterbury back to England, to bring together all the barons, and to make them swear allegiance to John, Duke of Normandy, son of King Henry, son of the Empress Matilda. The repugnance felt towards him was very general, but the fear of anarchy decided several noblemen in favor of John; promises and presents influenced others, and, on the 25th of May, 1199, when John arrived in England, the greater number of the barons had become reconciled to his cause. The new king was crowned on the 27th of May at Westminster, the primate proclaiming aloud that the crown of England was not an inheritance descending by right of primogeniture, but that it belonged to the worthiest claimant. The worthiest claimant on this occasion was Prince John.

There had been no question raised about the rights of Arthur; but Philip-Augustus was too shrewd not to seize this pretext for renewing the war against John, whom he knew to be a coward, a sluggard, and a sovereign unpopular in his kingdom; he claimed, therefore, in the name of the young prince, whose mother had placed him under the royal protection, nearly all King John's continental domains. Hostilities recommenced, and Brittany was ravaged both by its enemies and friends; but the King of France was engaged in a serious dispute with the Pope; his kingdom had just been placed under an interdict; he concluded peace with John, sacrificing, without remorse, the interests of Arthur, who found himself completely disinherited through the mutual understanding between his uncle and the King of France.

Meanwhile John had started out for Aquitaine, there to receive the homage of his subjects. He met, at one of the fêtes which were celebrated, Isabel, daughter of the Count of Angoulême and wife of the Count of Marche; she was remarkably beautiful, and as ambitious as she was beautiful. Her beauty attracted the king, and the ambition of the countess prompting her, she abandoned her husband to marry John Lackland, who himself had been married for ten years to the daughter of the Earl of Gloucester. An insurrection soon broke out in Aquitaine; it was insignificant at first, but at the beginning of the year 1202 Philip-Augustus, delivered from his quarrels with Pope Innocent III., stirred the flame of the rebellion in the southern provinces, organized an insurrection in Brittany, and suddenly took up Arthur's cause again, who had recently lost his mother. "You are aware of your rights," he said to the young prince, "do you wish to become king?" "Decidedly I do," said Arthur. "Very well then," said Philip, "there are two hundred knights, take them and march against your own provinces whilst I enter into Normandy." The Bretons rallied round their young duke, who advanced with his little army against the town of Mirebeau in Poitou, where his grandmother Eleanor was staying, whom his mother had taught him to hate. He hoped, by capturing her, to obtain better conditions from his uncle; but the old queen defended herself valiantly, and held the castle sufficiently long to allow her son to come to her assistance. A nobleman of the country delivered up the town to him on the night of the 31st of July, 1202, on King John's promising not to do any harm to his nephew. All the noblemen who supported the young duke, amongst whom was the Count of Marche, were made prisoners, and Prince Arthur himself was imprisoned in the Castle of Falaise, whence he was transported a short time afterwards to Rouen. There all trace of him is lost in history, and no information concerning him exists except vague and contradictory tradition. The most probable story relates that the king arrived by night with his esquire, Peter of Maulac, to see the unfortunate young prince in his dungeon, and that he took the latter with him in a little boat upon the Seine. The young man was in fear, and begged his uncle to spare his life; but John made a sign and De Maulac, after plunging his dagger into the prisoner's heart, threw his body overboard; but it is also said that De Maulac conceived a horror of the crime beforehand and refused to commit it, and that the king himself struck the fatal blow. It was on the 3rd of April, 1203. Rumors of the murder spread throughout France and England, adding fresh indignation to the hatred which John already inspired. The Bretons proclaimed Alice of Thouars, daughter of the Duchess Constance by her third husband, instead of Prince Arthur's sister, Eleanor, the Pearl of Brittany, who was in the power of her uncle, and was shut up by him in a convent at Bristol. The appeal of the Bretons to the liege-lord was listened to by Philip-Augustus; he summoned John, Duke of Normandy, to appear in Paris to be judged by his peers. Queen Eleanor had retired to Fontevraud, where she had taken the veil, overcome, it is said, with despair in consequence of her son's crime.

John had not answered Philip's summons: he was at Rouen, occupied with the festivities, while the King of France had entered Poitou, supported by the nobility, who had generally revolted in his favor, and was marching from there into Normandy. The Bretons had commenced the attack, and were advancing, pillaging the country. Many Normans joined them, so great was the horror inspired by the murder of Prince Arthur. The people had also organized an insurrection in Anjou and Maine, and Philip had taken possession of all the towns on his way when he effected a junction with the Bretons at Caen. "Let them go where they please," John would say in the midst of his revels, "I will take back in one day all that they have acquired with so much trouble." But the French army having appeared at Rodepont, in the neighborhood of Rouen, the King of England fled in great haste and recrossed the Channel in the month of December, 1203, in order to seek for succor.

The English reinforcements did not arrive; Rouen had defended itself valiantly; but the citizens had at length yielded in consequence of a famine; Verneuil had just been taken; Castle Gaillard, fortified by Richard Cœur-de-Lion, capitulated after a siege of seven months. The garrison had defended tower after tower; there no longer remained a single French knight, when the French soldiers at length destroyed the last portion of the ramparts. John had not lifted a finger to defend his dominions, and the King of France was regaining possession of his duchy of Normandy, which had been separated from his dominions for two hundred and ninety-two years. Brittany, Touraine, Anjou, Maine, and Poitou slipped from the grasp of the King of England; Aquitaine alone remained to him. King Philip, who was now satisfied, allowed himself to be persuaded by a legate sent by the Pope and concluded a truce of two years' duration with King John, which was to commence in the month of December, 1206.
