Henry Vl ruled England from 1461, but then his brother Edward lV took the throne.
Henry Vl was a little bit mental. He went through periods where he wouldn't even eat.
Even though Henry Vl was a little crazy, he had a wife. Her name was Margaret of Anjou, and she easily manipulated him.
Edward lV was a wise king but sometimes he was a little lazy.
I think he is not guilty because the article I read said that this story of him being a murderer could've been made up by one of his enemies.
Also, this article said "An English Knight who was loyal to Richard III later confessed that he killed the princes under Richard’s orders."
Two hundred years after their deaths, two skeletons were found under a staircase in the Tower of London. They were confirmed to be the skeletons of two young boys which could've been the two princes.
