Which of the following Plantagenets do you most blame for the downfall of the dynasty?
Imo it’s Edward IV. He was an idiot to marry Elizabeth Woodville and leaving his widow and young sons at the mercy of the clashing Woodville and Gloucester factions was very much avoidable. If Edward IV had married Bona of Savoy the Plantagenets likely would’ve at least lasted a few more generations. All of the following people are culpable to some degree though in my opinion.
