Catherine of Aragon was Princess of Wales as the wife of Arthur, Prince of Wales, and Queen of England as the first wife of King Henry VIII of England. For six months, she served as regent of England while Henry VIII was in France. During that time the English won the Battle of Flodden, an event Catherine played an important part in. The controversial book The Education of Christian Women by Juan Luis Vives, which claimed women have the right to an education, was dedicated to and commissioned by her.
