Richard returned to London in triumph, as he well deserved, vowing that he had that day won back the realm of England, which had been as good as lost. Soon the nobles and their armed retainers began to gather to London, and when they found themselves in force, they began to discuss the legality of the king's concessions to the peasants. He had not, it was urged, the right to give away other men's property--namely, their feudal rights over their vassals--without the consent of Parliament. It was shocking, too, that the murderers of the archbishop, the lord chief justice, and the treasurer, should go unpunished. So Richard's charter was annulled and his general pardon cancelled; all the leaders of the revolt were caught one after another and hanged; even John Ball's priest's robe did not save him from the gallows, though clergymen were so seldom executed in the Middle Ages. [Sidenote: =Decay of villeinage.=] When Parliament met, the king proposed to them that his promise to the insurgents should stand firm so far as the abolition of villeinage was concerned, since this had been the main cause of the rising. But the barons and knights of the shire were loth to give up their feudal rights, and refused to confirm the king's grant; they replied that the trouble had really had its origin in the evil governance of the ministers, and turned them all out of office. Nevertheless, the rising had not failed in its object, for in future the lords of the manors were afraid to enforce the full letter of their claims over the peasants, and villeinage gradually sank into desuetude. [Sidenote: =Richard assumes the government.=] King Richard had shown his high spirit in the days of the rising, and four years later, when he had attained the age of eighteen, he endeavoured to take the reins of power into his own hands. His uncle of Lancaster did not gainsay him, for he felt himself to be unpopular with the nation, so he departed over-sea on a vain errand. In right of his wife Constance, the daughter of Pedro the Cruel, he had a claim to the crown of Castile, and trusted to get aid from the Portuguese, to set him on the throne which Henry of Trastamara had usurped. So he gathered his retainers and many hired soldiers, and sailed away to Spain; nor was his face seen in England for more than four years. [Sidenote: =His ministers.=] Meanwhile the young king had placed his friends in office, and strove to rule for himself. His chief minister was Michael de la Pole, son of a rich merchant at Hull, whom he made Earl of Suffolk, to the disgust of many of the barons. He also favoured greatly Robert de Vere, whom he made Lord-Deputy of Ireland, and created Marquis of Dublin. In them and in his two half-brothers, Thomas and John Holland, he placed his confidence.
