Catherine of Aragon was the first-ever female ambassador in Europe. She was named the ambassador from the kingdom of Aragon to England in 1507.
At the time, Catherine was the 22-year-old widow of the former crown prince, Arthur. He had died in 1502, and Catherine had stayed on in England and become betrothed to the new crown prince, Henry. It was not because Henry particularly wanted her. No, Catherine was still in England because her father-in-law King Henry VII did not want to give back Catherine’s very large dowry.
Catherine’s position was precarious.
She had little money, as neither her parents nor her penny-pinching father-in-law wished to support her financially. She had no status, as her husband was dead and her betrothed had remained just that for going on three years. Naming Catherine ambassador, therefore, was less a compliment to her diplomatic skills and more a way to bolster her position and therefore her parent’s.
