John Knox (c. 1514 – 24 November 1572) was a Scottish clergyman and a leader of the Protestant Reformation who brought reformation to the church in Scotland. He was educated at the University of St Andrews or possibly the University of Glasgow and was ordained to the Catholic priesthood in 1536. Influenced by early church reformers such as George Wishart, he joined the movement to reform the Scottish church. He was caught up in the ecclesiastical and political events that involved the murder of Cardinal Beaton in 1546 and the intervention of the regent of Scotland, Mary of Guise. He was taken prisoner by French forces the following year and exiled to England on his release in 1549.
