Wikipedia:Articles for deletion/List of Doctor Who historical characters
The use of historical characters in ''Doctor Who'' is certainly an important part of the show and its own history. That ''Doctor Who'' did this is something that should be and is described in the ''Doctor Who'' article, with some pertinent examples. That's where your first two references come in. However, that's not a reason for an unreferenced, -style list here that makes no distinction between the very different uses, from an  perspective, of historical characters in the William Hartnell era with Barack Obama appearing in ''The End of Time'' or Nefertiti in "Dinosaurs on a Spaceship". Your third reference fails RS (not independent), so only your fourth reference directly speaks to an article like this, and it's not the job of an encyclopaedia to replicate a lazy listicle clickbait article
