I love it when people talk about the Royal Family’s history!
Most of the vilification of R3 was courtesy of the Tudors. Henry VII fended off multiple uprisings by people claiming to be one of the Princes as well, and Henry VII and his successors were really sensitive about their relatively weak claim on the crown.
One of the the biggest piece of propaganda about R3 was from Shakespeare who really played up the crooked cowardly hunchback thing.
Henry VII actually took pity on one of the attempted usurpers because I think the boy was so young at around ten years old, so after crushing his army, Henry gave him a job and the lad ended up caring for the King’s birds of prey. Later, older lads weren’t so lucky.
On a similar note of misrepresented Kings, I believe that King John was actually a very good King contrary to the Robin Hood nonsense. His brother, Richard the Lionheart didn’t spend very long in England at all and was only interested in his French interests and plundering the Middle East. A lot of the tax efforts was part of financing the “Lionheart’s” war machine and was part of the political struggle between a medieval King and his nobility over power.
Also, I always wondered if Edward II was unlucky in that he comes across as a very Renaissance style King, who was unfortunately born into the height of the medieval period where being a bit of an educated fop was a liability. His wife Isabella was something though, even if she did have him murdered.
