History Recommendations Thread (YouTube channels, documentaries, books, etc.)

[u/Jane_the_Quene]

This sub frequently has people asking for quality history YouTube channels, books, etc., and it comes up regularly. The mod team thought maybe it could be consolidated into one big post that people can interact with indefinitely.

For the sake of search engines, it's probably a good idea to state the topic (e.g., "Tudor history channel" or "WWII books" or just "Roman Republic" or whatever).

Okay, folks. Make your recommendations!
