The China History Podcast comes all the way from sunny Claremont, California, courtesy of Laszlo Montgomery, and is highly recommended. I’ve been listening to it on and off since last summer and have learnt a lot from it.
It’s a great introduction to some key episodes and themes in Chinese history, and the host has a nice, calm, leisurely style of delivery that makes a good contrast for turbulent history he is usually recounting. And at 3-4 episodes a month, of 30+ minutes each, this guy is amazingly productive.
