Juana I of Castile (1479-1555) was the third child of Isabella of Castile and Ferdinand of Aragon. She's remembered now for being "Juana La Loca/Juana The Mad" but, in fact, that reputation was just part of a larger scheme that found her caught between her ambitious and terrible husband and her ambitious and terrible father.
