Queen Isabella of Castile, half of the famous pair Isabella and Ferdinand of Castile and Aragon, was never supposed to be queen. She was born in 1451 to King John II of Castile. He already had an heir, the twenty-six-year-old Henry, from his first marriage. And two years after Isabella, a second son was born, Alfonso. Isabella was third in line behind two men.
Fate happened in such a way that both died with children, though, and Isabella was suddenly heir to the throne. Well, Henry had a daughter. But rumor had it she wasn’t his true, legitimate daughter, and Isabella took the throne instead after a little bit of war.
