He was responsible for the deaths of several members of his own family, including his nephews, King Edward V and Richard, Duke of York, and his brother, George, Duke of Clarence. He also ordered the execution of several of his political opponents.
However, he was also a patron of the arts and learning. He founded a school in York and supported several universities. He was also a skilled military leader and won several battles against his rivals.
Richard's reign was ultimately short-lived. He was defeated and killed at the Battle of Bosworth Field in 1485 by Henry Tudor, who became King Henry VII.
The Tudors tried to portray Richard as a tyrant and a monster, and this image of him has persisted in popular culture. However, there is also evidence that he was a capable and intelligent ruler who was loyal to his supporters.
