“….If we ignore Lady Jane Grey, then the monarch with probably the
shortest reign was Edward V. (Right now I can’t think of anyone else.) He succeeded his father on April 9, 1483, at the tender age of 12. His uncle took him and his brother to the Tower of London “for their protection.” Seventy-eight days later both boys vanished and the uncle was proclaimed King Richard III….”
So, although this article (another potted history) doesn’t actually level a bony, theatrically quivering finger at Richard, there is nevertheless the usual nudge-nudge-wink that he did away with his nephews. I wouldn’t mind if there was an extra sentence to point out that no one knows what happened to the boys, and that others had strong motives for wanting them gone.
I think they were hidden away, both to protect them from Tudor/Beaufort designs, and to prevent them from becoming the focus of rebellion against Richard. If Richard wanted them dead, he’d have had it done and then made much of their demise, probably putting their bodies on display. The fact that he didn’t tells me (IMO, please note) that he knew they were safe. He had them hidden away so securely that to this day we haven’t a clue of the whereabouts.
In my opinion they survived secretly and safely into the Tudor period and kept their heads well down to continue in secret safety. They were in far more danger from the Tudors and Beauforts than they’d ever been from Richard, because Henry Tudor had made them legitimate again and couldn’t afford for them to reappear to out-claim him!
