The image of Catherine of Aragon has always suffered in comparison to the vivacious eroticism of Anne Boleyn. But when Henry VIII married Catherine, she was an auburn-haired beauty in her 20's with a passion she had inherited from her parents, Isabella and Ferdinand, the joint-rulers of Spain who had driven the Moors from their country. This daughter of conquistadors showed the same steel and sense of command when organising the defeat of the Scots at the Battle of Flodden and Henry was to learn, to his cost, that he had not met a tougher opponent on or off the battlefield when he tried to divorce her.
