- Patrick Wyman's "Fall of Rome" [ http://wondery.com/wondery/shows/fallofrome/ ] and "Tides of History" [ http://wondery.com/wondery/shows/tidesofhistory/ ]. Good discussion of the Late Imperial period and of the Early Modern Era. Main disadvantage is that the sponsor messages are like commercials in that they abruptly butt into the middle of the episodes.
- "History on Fire" [ http://historyonfirepodcast.com/episodes/ ]. I find these episodes a little hit and miss, and the narrator's thick accent does take some getting used to, but it's definitely worth a try.
- "MartyrMade" [ http://historyonfirepodcast.com/episodes/ ]. Probably the closest to Dan Carlin in terms of style, where he's using history as a jumping-off point to explore questions about the human condition. Currently it contains a history of Zionism and the Israeli-Palestinian conflict, and also an analysis of cannibalism and ritual sacrifice in history (a companion series to the "History on Fire" episodes about the Aztecs).
One day I figured I should at least see what everyone was talking about, so I started listening during a bike ride. It made me want to exercise more, just so I could hear the next part of the story.
I was never very much into history. But it didn't matter because this series is amazing. I would recommend "Blueprint for Armageddon" about the first world war, but be warned that it's very long. If you want something shorter (it's still almost 6 hours!) try "The Destroyer of Worlds".
But really, pretty much everything is fantastic.
