Dan Carlin's ~9-hour Wrath of the Khan's Series about Genghis Khan and the Mongols is an astonishingly good listen. Yeah, it's 9 hours across 5 separate podcasts, but it's riveting. Few can tell a story as well as Dan. It'll cost you $9.99, but I'm so sure you'll love it that I'll give you your money back if you don't think it was worth it.

Twitterfolk, thank you. Two weeks ago, I asked for the best history podcast episode you'd ever heard. About 30% of you said Hardcore History "Wrath of the Kahns" series on Genghis and the Mongol Empire. OMFG did you guys nail that gift. Absolute masterpiece.
