In OTL King Edward IV died from an unknown illness in 1483 aged 41 leaving the crown to his underage son Edward V with Richard of Gloucester as his guardian (and regent) which lead to Richard usurping the crown shortly after.
Numerous causes have been suggested for his death like typhoid fever, pneumonia, unhealthy life or even poisoning.
Anyway i was wandering what would happen if Edward IV managed to survive his illness (or the alleged poisoning) and lived till 1490s-1500s?
Would Richard of Gloucester attempted to usurp the crown with Edward around? Could a mature Edward V handle the situation better when he became King around 1490s-1500s?
