Again, I don't know all that much, but here's a website I found that's pretty interesting: http://www.koreanhistoryproject.org/Ket/index.htm I never have gotten through it ALL though...
For a handy and very useful Korean history book, I'd recommend Keith Pratt's Everlasting Flower ((Reaktion Books,Great Britain:2006) - http://www.amazon.com/gp/product//186189273X/ref=cm_rv_thx_view/002-7139025-7230408 There are some interesting online sources too: Dakin Burdick's History of Hapkido Dakin Burdick's History of TKD (Excellent) Alternative version (Korean authors)
