Great question Sarah! I would say it was “legal” only in the sense that the British Parliament supported it. I do not believe there was a royal bloodline. But then, the same is almost true of Henry Tudor. His connection was distant! See you tomorrow!
HI Sarah! I discovered something interesting today. You had me thinking more deeply about your question, and I found out that the Duke of York was in fact the great grandson of Edward III. So, there was a royal lineage to the throne! When he became Lord Protector, it was with the agreement that he would become king upon Henry VI’s death, but of course, the Duke was killed in battle and he never was king.
The one blogger on Instagram launched a huge series of posts about this war. He bought auto likes from https://soclikes.com/ to draw as much as he can attention to these posts. And his opinion was that is did not be legal claim.
