October 19 – Isabella I of Castile marries Ferdinand II of Aragon

On this day in history, 19th October 1469, eighteen-year-old Isabella I of Castile married seventeen-year-old Ferdinand II of Aragon.

Their marriage may have happened outside of the Tudor period, and in Spain, but it had an impact on Europe and has links with the Tudors.

The couple became the famous "Reyes Catolicos", the Catholic monarchs, and brough together two powerful kingdoms, which comprised most of what is modern-day Spain. They were also the parents of Catherine of Aragon, who married Arthur Tudor, Prince of Wales, and, after his death, King Henry VIII.
