Why did king henry viii of england want an annulment or divorce from catherine of aragon? catherine was the daughter of king ferdinand and queen isabella of spain, who would not share their american colonies. the swiss thinker john calvin influenced henry to find a protestant wife. he wanted to start a protestant church in england, but catherine was catholic. he wanted to remarry because catherine did not produce a male heir to the throne?

I think the answer is he fell in love with another woman whose name is  Anne Boleyn in 1527. He wanted an annulment because he already has a relationship with Anne. He believed that for being the King of England he has the right to have a divorce, however this was subject to Catholic Church decision. In the end, Cardinal Wolsey wanted to gain the King's support and the Christian monarch so he made a decision that the marriage of King Henry VIII and Catherine was invalid.
