I hope it is ok to ask for book recommendations here...I checked the book list and the section on Korea is 20th C. only.
My question is: is there something like Palmer's A History of the Modern World that focuses on the Korean Peninsula? I would really like a sweeping overview of the cultural, political, and economic history of the area, if it exists.
Korea's place in the sun: A Modern History by Bruce Cumings might be what you're looking for
