In the fourteenth century, John Wyclif, educated at Oxford and influenced by the nominalism of William of Ockham, gave "learned heresy" a common audience. Like the Waldensians, the Lollards translated the Bible into their vernacular language, English. The Lollards were the most significant heretical group in England before the Reformation. Interestingly, Wyclif's teachings were influential for John Hus in Bohemia, the leader of another great medieval heretical group, the Hussites. Wyclif was condemned by popes Gregory XI and Urban VI on several occasions. Even after his death, Wyclif's heretical teachings were addressed at the Council of Constance in 1415.
Followers of Wyclif came to be known as "Lollards." Perhaps the name was derived from the Dutch term lollaerd, meaning mumbler. The sect was driven out of Oxford in 1382, but some devout members circulated Wyclif's teachings as well as the 1394 "Lollard Conclusions."
