The Protestant Reformation began in 1517 when Martin Luther publicly challenged certain Catholic Church doctrines and practices. He was troubled by the Church selling indulgences to lessen time in purgatory and believed salvation came through faith alone, not works. Henry VIII later formed the Church of England in 1534 when the Pope refused to annul his marriage. John Calvin furthered the Reformation by believing in predestination and advocating for a life without sin. The Reformation ultimately led to the formation of new Protestant denominations like Lutherans, Puritans, Baptists, Presbyterians, and others.
