I listen to way too many podcasts, history ones included. Dan Carlin’s Hardcore History is quite good, there’s Jaime Jeffers’ British History Podcast, Karina Longworth’s You Must Remember this about the history of Hollywood, and Robin Pierson’s History of Byzantium podcast was invaluable when prepping for the Battle of Blackwater.
In terms of my own podcast, I do podcast with Lawyers, Guns, and Money, although we’re a bit infrequent. I have plans to do a labor history podcast down the road, but I’m way too busy at the moment.
