Kind of what it says on the tin, what are the history podcasts that historians recommend most? Are the more popular history podcasts like History of Rome/Byzantium/Egypt, hardcore history, and others, reliable as secondary sources?
This sub has a podcast as well, check it out, you are sure to find a good few episodes which are to your liking. Since most of the interviewed people are also quality contributors here, I am fairly certain they would recommend the podcast wholeheartedly :)
