Revolutions Podcast is good and well researched (Especially later seasons).

The History of the Germans Podcast is really great (100+ episodes from Ottonians just to Habsburgs, so its pretty well in depth).

History of France Podcast is good, its from a University professor, but not overly academic but well researched.

History of England Podcast is good as well, starting with Anglo Saxon and Post Roman England. He uses a lot of high quality and primary sources.

A History of Italy podcast starts with the end of Rome and is 200 episodes to get to 1500.

I like in depth, single topic podcasts as you can tell as opposed to the podcasts that jump around topics.
