It was right after this guy’s time that the Catholic and Protestant forces in England and Scotland started killing each other in earnest..................
Disagree to the use of a capitalized 'Protestant' in your comment, especially given that Martin Luther was not born until 1483 and his Ninety-five Theses of 1517. While there were numerous protestants against the monolithic established Church (aka Roman Catholic Church) in the British Isles and Europe, none were, at that time, so designated!
The largest, and ongoing resistance to said establishment in Britain, was from the followers of John Wycliffe (1331-84), knowns as Lollards, who were frequently seized, imprisoned and killed as heretics in the years prior to being subsumed into the Protestant Revolts.
