A king made his subjects worship the corpse of his beloved
This case of star-crossed lovers got weird fast. In fourteenth-century Portugal, the king’s son, Don Pedro, fell in love with Inês de Castro. There were only a couple of problems with this: for one, his father, King Afonso IV, did not approve, because Inês was illegitimate.
For another, Don Pedro was married. His father had arranged for him to marry a noblewoman named Constanza. Inês was Constanza’s lady-in-waiting. When Don Pedro refused to stop seeing her, the king had her killed.
When Don Pedro acceded to the throne two years later, he exhumed her body, had it clothed in royal dress, and “crowned” her queen. According to historical legend, he made the other nobles all kiss her hand as a sign of their devotion. These are the history questions everyone gets wrong.
