I have turned at least one friend onto history podcasts using Mike Duncan's work. Now our wives look at us like we're a bunch of two headed goats whenever we meet and talk referncing revolutionary figures and events, raving about how much more "you feel the history" when visiting Rome and Paris and know some of the history. It's great!
I just finished carlins kings of kings episodes before visiting the british museum. Carlin mentioned the contrast between what was depicted in the Assyrian and Achaemenid empires palace/throne and being able to see it in the museum with the added context made me appreciate it so much more.
Visited Rome/Pompeii with my GF and she said it was like having a private tour guide. I just felt like I knew so little and could only add sparse bits of context.
Dan Carlin has a great radio voice, and is an entertaining presenter. Hardcore history is really only okay on the history front though. Plus they are relatively shallow with how short they are.
I think Carlin himself would be the first to admit that, even does so in the intro to many episodes. I think he already suffers from the length of some of his series.
Revolutions is my go-to. I also listened to History of Rome from Duncan. And because of this History of Byzantium is on my to check out list as well. I will try the others you mentioned. I'm very eager to find others as in depth as revolutions. Thanks!
