Step 1 : Introduction to the question "Which of King Henry VIII’s six wives was married to him the longest?"
...Catherine of Aragon, Henry VIII’s first wife, was married to him for nearly 24 years, from June 1509 until their marriage was annulled in May 1533. Their marriage lasted longer than his other five marriages combined. Catherine had previously been married to Henry’s older brother, Arthur, who died in 1502. Her marriage to Henry produced one surviving child, the future Queen Mary I of England. Henry’s desire for a male heir and his determination to marry Anne Boleyn led him to seek an annulment of their lengthy marriage.
