Sebastião of Portugal
16th King of Portugal from 1557 to 1578. He was made a King when he was only 3 years old, dying in the battlefield of the battle of Alcácer-Quibir when he was only 24 years old. Though, by popular belief he never died, only disappeared in the fog, and the Portuguese people still wait for his return. His body was never found.
There were rumors that he was a girl disguised as a man so he could be the King. He was oddly girly looking.
