My only question about Henry's involvement was the two pretenders: Perkin Warbeck and the Irish! Lambert Simnel. Why was Henry so cruel to Warbeck? Surely, he must have suspicions he was Richard of York...
One thing that people generally don't know about Richard the Third is that there was another nephew who came before him in ascendancy to the throne: his brother George's son. But he was killed by Henry the 7th, not Richard...
I’m under the impression that Warbeck was Richard of York. All the other houses of Europe thought so. And no way would the king of Scotland let his relative (his niece I think) marry Warbeck if he didn’t think that Warbeck was royalty.
