Although you forgot to include the options, here I leave some facts about the Catholic monarchs, Ferdinand of Aragon and Isabella of Castile that may be useful:
- The marriage was held in Valladolid in 1469 AD. It was a private and secret wedding since Isabella had no permission from her brother, king Henry IV of Castile.
- In order to celebrate the union, Ferdinand and Isabella requested special permission from the Pope, since they were cousins. As it had not arrived on time, they used false documents. They received the official permission only two years later.
- It was a union of crowns, not of kingdoms: this means that Castile and Aragon remained separated kingdoms, but shared King and Queen.
- Ferdinand was considered the "consort king" of Castile. This means that political decisions were taken by Isabella.
