Protestant ideas were popular in Henry VIII's reign, although not universally accepted. Henry VIII himself began his reign as a staunch Catholic, and it was not until 1534 that he declared himself the Supreme Head of the Church of England. This allowed him to break away from the Catholic Church and introduce Protestant reforms.
During his reign, Henry VIII implemented the Act of Six Articles, which reinforced traditional Catholic beliefs and practices. This caused a rift between Henry and some of his Protestant supporters, who felt that he was not doing enough to promote Protestantism.
In 1539, Henry VIII issued the Act of Six Articles, which allowed for some Protestant reforms to be implemented. This included the introduction of the Book of Common Prayer, which replaced the Latin Mass with English services. This was seen as a major step forward for Protestantism in England.
Henry VIII's reign also saw the introduction of the King James Bible, which was the first English translation of the Bible. This was seen as a major milestone for Protestantism in England, as it allowed people to read and understand the Bible in their own language.
Overall, Henry VIII's reign saw a gradual increase in the popularity of Protestantism in England, although it was still not universally accepted. Henry VIII's own religious beliefs were a source of controversy during his reign, and his actions often angered both Catholics and Protestants.
