Final answer:
Henry VIII started his own church, the Church of England, because he wanted an annulment from his first wife, Catherine of Aragon, but the Pope refused. He also disagreed with some of the practices in the Catholic Church and disliked the selling of indulgences.
Step-by-step explanation:
King Henry VIII started his own church, the Church of England, for several reasons. Firstly, he wanted an annulment from his first wife, Catherine of Aragon, but the Pope refused to grant it. As a result, Henry created a new national Protestant church so he could annul his own marriage and marry Anne Boleyn. Secondly, Henry disagreed with some of the external practices of the Catholic Church. Finally, Henry disliked the selling of indulgences, which the Catholic Church used as a way to make money and promote the idea that people could 'buy' their way into heaven.
