Stefan Molyneux's series on historical figures is pretty based.
I'm quite found of The Great War, even if it does repeat the donkeys led by lions myth sometimes. The "This Week 100 Years Ago" format is pretty cool, and the research is reasonably accurate. It helps that they're open about what sources they use.
