The rebellion, therefore, had failed either to abolish villeinage in the countryside or to end municipal oligarchy in the towns, and many lords took the opportunity of the time of reaction in order to revindicate old claims over their bondsmen. Nevertheless serfdom continued to decline all through the latter years of the 14th century, and was growing obsolete in the 15th. This, however, was the result not of the great revolt of 1381, but of economic causes working out their inevitable progress. The manorial system was already doomed, and the rent-paying tenant farmers, who had begun to appear after the Black Death, gradually superseded the villeins as the normal type of peasantry during the two generations that followed the outbreak that is generally known as "Wat Tyler's rebellion." Wycliffe and the Lollards. King Richard, though he had shown such courage and ready resources at Smithfield, was still only a lad of fourteen. For three years more he was under the control of tutors and governors appointed by his council. Their rule was incompetent, but the chief danger to the realm had passed away when both Charles V. of France and his great captain Du Guesclin died in 1380. The new king at Paris was a young boy, whose councils were swayed by a knot of quarrelsome and selfish uncles; the vigour of the attack on England began to slacken. Nevertheless there was no change in the fortune of war, which continued to be disastrous, if on a smaller scale than before. The chief domestic event of the time was the attack of the clerical party on Wycliffe and his followers. The reformer had begun to develop dogmatic views, in addition to his old theories about the relations of Church and State. When he proceeded to deny the doctrine of transubstantiation, to assert the all-sufficiency of the Scriptures as a rule of life, to denounce saint-worship, pilgrimages, and indulgences, and to declare the pope to be Antichrist, he frightened his old supporter John of Gaunt and the politicians of the anti-clerical clique. They ceased to support him, and his followers became a sect rather than a political party. He and his disciples were expelled from Oxford, and ere long the bishops began to arrest and try them for heresy. Wycliffe himself, strange to say, was not molested. He survived to publish his translation of the Bible and to die in peace in December 1383. But his followers were being hunted, and imprisoned or forced to recant, all through the later years of Richard II. Yet they continued to multiply, and exercised at times considerable influence; though they had few supporters among the baronage, yet among the lesser gentry and still more among the burgher class and in the universities they were strong. It was not till the next reign, when the bishops succeeded in calling in the crown to their aid, and passed the statute _De heretico comburendo_, that Lollardy ceased to flourish. Richard's personal rule. Impeachment of the king's "favourites."
