Did Thomas Moore describe Richard III as a hunchback? Seems he was right, doesn’t that lend more credence to his story of Richard III as the murderer of the Princes?
Cheated of feature by dissembling Nature,
Deform’d, unfinish’d, sent before my time
Into this breathing world, scarce half made up-
And that so lamely and unfashionable
That dogs bark at me, as I halt by them-
Why, I, in this weak piping time of peace,
Have no delight to pass away the time,
Unless to spy my shadow in the sun,
And descant on my own deformity.
And therefore since I cannot prove a lover
To entertain this fair well-spoken days,
I am determine’d to prove a villain,
And hate the idle pleasure of these days.
~Shakespeare~
Henry VII set up an enormous campaign of state-sponsored vilification against Richard III after his death. This is because his own claim to the throne was very tenuous.
Many believe that Henry VII had the princes killed just before Titulus Regius was signed into law.
Titulus Regius gave Elizabeth of York (Henry's wife) a claim to the throne - and so gave Henry VII a claim to the throne. But at the same time it gave the Princes in the Tower a better claim to the throne than Henry VII - he had a very good reason to kill them.
