Wycliffe argued that scripture was the best guide to understanding God's intentions, and that the superficial nature of the liturgy, combined with the abuses of wealth within the Church and the role of senior churchmen in government, distracted from that study. A loose movement that included many members of the gentry pursued these ideas after Wycliffe's death in 1384 and attempted to pass a Parliamentary bill in 1395: the movement was rapidly condemned by the authorities and was termed "Lollardy". The English bishops were charged to control and counter this trend, disrupting Lollard preachers and to enforcing the teaching of suitable sermons in local churches. By the early 15th century, combating Lollard teachings had become a key political issue, championed by Henry IV and his Lancastrian followers, who used the powers of both the church and state to combat the heresy. Pilgrimages were a popular religious practice throughout the Middle Ages in England, with the tradition dating back to the Roman period. Typically pilgrims would travel short distances to a shrine or a particular church, either to do penance for a perceived sin, or to seek relief from an illness or other condition. Some pilgrims travelled further, either to more distant sites within Britain or, in a few cases, onto the continent. During the Anglo-Saxon period, many shrines were built on former pagan sites which became popular pilgrimage destinations, while other pilgrims visited prominent monasteries and sites of learning. Senior nobles or kings would travel to Rome, which was a popular destination from the 7th century onwards; sometimes these trips were a form of convenient political exile. Under the Normans, religious institutions with important shrines, such as Glastonbury, Canterbury and Winchester, promoted themselves as pilgrimage destinations, maximising the value of the historic miracles associated with the sites. Accumulating relics became an important task for ambitious institutions, as these were believed to hold curative powers and lent status to the site. Indeed, by the 12th century reports of posthumous miracles by local saints were becoming increasingly common in England, adding to the attractiveness of pilgrimages to prominent relics. Participation in the Crusades was also seen as a form of pilgrimage, and indeed the same Latin word, "peregrinatio", was sometimes applied to both activities. While English participation in the First Crusade between 1095 and 1099 was limited, England played a prominent part in the Second, Third and Fifth Crusades over the next two centuries, with many crusaders leaving for the Levant during the intervening years.
