Why Henry VIII decided to set up the Church of England?

It was actually King Henry VIII and he actually did not create the church of England. The king did however seperate it from the Roman Catholic Church. He did this because he was dissatisfied with his marriage to Catherine of Aragon due to her inability to bear him a son and he was infatuated with Anne Boleyn, a younger woman. Because the Roman Catholic Church and Pope Clement VII refused to give the King an annulment (an end to his marriage), Henry VIII took religious matters into his own hands, separating the Church of England from the Pope's control and annulling his marriage to Catherine.
