Because he wanted to get his first marriage with Catherine of Aragon annulled.
Explanation:
Henry VIII was the King of England from 1509 to 1547. He succeeds his father Henry VII as the second Tudor monarch.
He is best known for his six marriages. His first marriage was with Catherine of Aragon but he wanted to get it invalidated. The Pope did not want the same so Henry initiates the English Reformation to separate the English Church from the papal authority. Because of that, he was excommunicated.
