@mournfulm0th: Happy 547th birthday to Joanna I of Castile! My favorite historical woman, and someone whose life and legacy has fascinated me for years. Born a princess of the Trastámara dynasty, she would become Queen of Castile and Aragon in her own right, yet spend much of her life deprived of the power and freedom that came with her crowns. Remembered by history as Juana la Loca, or Joanna the Mad, her story is far more complicated than the nickname suggests. #joannathemad #joannaofcastile #historytok #History #womenofhistory
