Often remembered as the "Forgotten Tudor King", Edward was just nine his father, King Henry VIII died and the young boy became King. Surrounded by advisors, he became further distanced from his beloved elder sister Mary. But by now they were divided not just by power and status, but also by faith. Mary was a staunch Catholic, Edward a reforming Protestant and the first Protestant King. In the Tudor world, such matters were not an issue of personal choice but matters of life or death, treason or heresy.
