What history podcasts would you most recommend to anyone?

Mike Duncan’s Rome Podcast and Revolutions podcast are both excellent.

Dan Carlin’s Hardcore History is a lot of fun.

Jaime Jeffers’ British History Podcast is quite good on everything 9th century and before (he’s still working his way through the life of Alfred the Great, so he’s got quite a bit of history to work through).

Robin Pierson’s History of Byzantium podcast was useful to me in researching the Battle of Blackwater.
