Catherine of Aragon was the first wife of Henry VIII and she did not agree with his desire to divorce her. She was a devout Catholic and believed that her marriage to Henry was valid and sacred. Catherine fought against the divorce, which ultimately led to significant political and religious changes in England, including the English Reformation and the establishment of the Church of England. Henry's desire for a divorce stemmed from his wish to marry Anne Boleyn, which he believed would provide him with a male heir, something Catherine had failed to do.
