There is no actual evidence that they were murdered at all, by Richard or anyone else. The popular belief that they were murdered by their uncle is based on rumour and hearsay, most of it written after the fact by people who weren’t around, or even alive, at the time, and once Henry VII had come to power and the Tudor propaganda machine had kicked in. We’ve seen very recently in our own time how rumour can quickly turn into scandal when it comes to the royal family.
Don’t get me wrong, they may very well have been murdered, and Richard may have done it, but in the absence of actual evidence it’s only right that when considering the question you should look at all of the possible outcomes and not accept one version of events as the undisputed truth.
Langley is very clearly biased, but I think her work has some merit in that it highlights what’s out there in the world in the way of an alternative narrative. Historians may have been aware of these documents before but the public at large weren’t. There are clear issues with the way the documentary presents them, mostly by ignoring entirely the fact that at least some of them may well have been propaganda pieces themselves to support a challenge to Tudor rule. But we don’t know either way. I’m currently reading her new book, as I find the whole topic fascinating, and I’ll be interested to see if the book considers that possibility.
If Charles ever gives permission to exhume the remains found in the tower, it should be possible to confirm whether or not they are the princes as John Ashdown-Hill, who traced Richard’s DNA, has managed to trace a maternal line of DNA for the princes. I haven’t read his book, but apparently he has examined the reports from the 1930s on the remains and thinks they may be Anglo-Saxon. They apparently also show a genetic dental condition which isn’t present in Richard’s remains which he says makes it less likely they are related. I think he’s a pretty big Ricardian, however, so once again, bias!
Daughter of Time is a brilliant read, highly recommend. I’d also recommend The Sunne in Splendour by Sharon K Penman, it’s fantastic. Highly Ricardian, but I’m fine with an antidote to the Shakespearean version 😁
