The daughter of Isabella I of Castile and Ferdinand II of Aragon, Catherine was three years old when she was betrothed to Arthur, Prince of Wales, heir apparent to the English throne. They married in 1501, but Arthur died five months later. She held the position of ambassador of the Aragonese crown to England in 1507, the first known female ambassador in European history.Catherine subsequently married Arthur's younger brother, the recently ascended Henry VIII, in 1509. For six months in 1513, she served as regent of England while Henry VIII was in France. During that time the English crushed and defeated the Scottish at the Battle of Flodden, an event in which Catherine played an important part with an emotional speech about English courage.
