The immediate result of the battle was the issue of a document called the Mise of Lewes, by which King Henry promised to keep the charter, to dismiss all his foreign relatives and dependents, and to place himself under the control of a privy council, whom Parliament should choose to act as his ministers and guardians.
Rule of Simon de Montfort.—Captivity of the king and Prince Edward.
A Parliament was hastily summoned and delegated three electors to nominate this privy council, namely, Earl Simon, the Earl of Gloucester, and the Bishop of Chichester. The electors, naturally but unwisely, appointed none but their own trusted supporters. Thus England came under the rule of a party, and a party whose violent action had been disliked by a great portion of the nation. The king was but a puppet in their hands; he was practically their prisoner, for three of the council always attended his steps and kept him in sight. Now, Henry, irritating and faithless as his conduct had always been, was not personally disliked, and the sight of their monarch led about like a captive and forced to obey every behest of his captors, was very displeasing to many who had formerly felt no sympathy for him. It was felt, too, that his son Edward was being very hardly treated by being kept in honourable captivity and deprived of all share in the government; for the prince had taken the side of reform till the outbreak of the civil war, had only joined his father when Simon took arms, and had behaved with great patriotism and self-denial in refusing to continue the struggle after Lewes.
For two years Earl Simon governed England, and the king was kept under close guard. This period was not one of peace or prosperity; the land was still troubled by the echoes of the civil war, and in his anxiety to maintain his dominant position the earl incurred many accusations of harshness and rapacity. He was especially blamed for depriving Prince Edward of his earldom of Chester, for favouring Llewellyn Prince of North Wales in his quarrel with Roger Mortimer, a great lord of the Welsh marches who had been on the king's side at Lewes, but most of all for giving too much trust and power to his own sons. The young Montforts were rash and arrogant men, who harmed the people's cause more by their turbulence than they aided it by their courage and fidelity. In short, they were as Samuel's sons of old, and wrought their father no small damage and discredit.
The Parliament of 1265.—Representation of Shires and Boroughs.
The chief event for which Earl Simon's tenure of power is remembered is his summons of the celebrated Parliament of 1265. This incident is noteworthy, not so much for anything that the Parliament did, as for the new system on which it was constructed. Hitherto the Great Council had usually been composed only of the barons and bishops, though on two or three occasions in the thirteenth century the smaller vassals of the crown had been represented by the summons of two knights from each shire, chosen in the county court by all the freeholders of the district. But de Montfort not only called these "knights of the shire" to his Parliament of 1265, but also summoned two citizens or two burgesses from each of the chief cities and boroughs of the realm. Thus he was the first to give the towns representation, and to put together the three elements, lords, borough members, and county members, which form the Parliament of to-day. It must be confessed that Simon's immediate object was probably to strengthen his own side in the assembly, rather than to initiate a scheme for the reform of the Great Council in a democratic direction. Many barons were against him, and them he did not summon at all. Many more were jealous or distrustful of him, and it was mainly in order to swamp their opposition that he called up the great body of knights of the shire and members for the towns,—for London and the rest of the chartered cities were strongly in favour of his cause.
This Parliament confirmed all Simon's acts; outlawed those of the king's party who had fled over-seas, and refused to accept the terms of the Mise of Lewes; imposed a three-years exile in Ireland on some of those who had made only a tardy submission, and put all the royal castles into the hands of trusty partisans of the earl. It made few regulations for the better governance of the realm, but left everything in Simon's hands and at his discretion.
Prince Edward escapes.
It was impossible that the regency of the great earl should last for long. There were too many men in England who felt that it was unseemly that the king and his son should live in close restraint, while one who, in spite of all his merits, was still a foreigner and an adventurer, ruled the realm. The beginning of Simon's troubles came from a quarrel with his own chief supporter, the young Earl of Gloucester. Gilbert de Clare thought that he was not admitted to a sufficient share in the government of the kingdom, and soon fell into a bitter feud with Simon's sons. His anger led him into conspiring against the great earl. By his counsel Prince Edward escaped from his keepers, by an easy stratagem and a swift horse. Once free, the prince called his party to arms, and was joined by Gloucester, Mortimer, and many of the barons of the Welsh marches.
