Which of his six wives was Henry VIII married to the longest?

Henry VIII was married to Catherine of Aragon the longest because their marriage lasted for more than 20 years. They got married in 1509 and their union only ended in 1533 when Henry sought an annulment, leading to a rift with the Catholic Church. Catherine of Aragon was a loyal and devoted wife to Henry, bearing him several children, of whom only one, Mary Tudor, survived infancy. Despite their long marriage, Henry's desire for a male heir and the political implications pushed him to seek a divorce, ultimately leading to Catherine's downfall and the dissolution of their marriage.
