Many universities have whole sites devoted to just a single dynasty of chinese history. They shouldn't be hard to find using a search engine.
A far more interesting way to learn about Chinese history is by renting videos (any video store specializing in Asian film should have them, particularly in Chinatown, if you have access to a major city.)
There has been several recent Chinese TV dramas on the Warring States Period. They run about 20 hours for each "set"(a story may have many sets...For example, I know Romance of Three Kingdoms...which deals with a later period at the end of Han Dynasty... has 6 sets) The best one IMHO being about Sun Tzu and his successors. It moves faster than the rest of them. Although I'm not sure if these are availiable sub-titled or dubbed in English.
