ir John Oldcastle was a knight
who had assisted Henry V in defeating the Welsh revolt and was a friend of the King. Oldcastle became the leader of a group of people called the Lollards who sought to change the way the Bible was taught and read the English Bible translated by John Wycliffe. Although a friend of the King's, Oldcastle was branded as a heretic and the penalty was death. Oldcastle was arrested in 1413 and imprisoned in the Tower of London. He managed to escape and plotted to capture the King but the plot failed and in January 1414, at a Lollard meeting, the Kings troops arrested many of the leaders of the movement. Oldcastle managed to escape. He was captured in 1416 and in December of that year was convicted by Parliament of treason and heresy. Oldcastle was executed in January 1417.
