Henry VIII became the king of England in 1509 and, soon after, married his brother's widow, Catherine of Aragon. Despite a happy and loving marriage, Queen Catherine did not give birth to a son and, after 18 years, the need for a male heir was stronger than ever. Henry appealed to the Pope for a divorce but his request was denied. After discussing the situation with his advisers, some of whom were Protestants, Henry decided to break with Rome and develop his own Church of England, in which he was the supreme leader and able to grant divorces. This means, then, that Henry's faith prompted him to change England's religion because it would not allow him to divorce his wife and marry Anne Boleyn, who was already possibly pregnant by Henry.
