Spectacular multifactional falls of empire

I'm reading a book on Coxinga right now, and the fall of the Ming is absolutely fascinating. Aside from the encroaching Manchu, the dynasty's fall was caused by the rise of peasant rebels such as Li Zicheng and Zhang Xianzhong. As the civil war continued, imperial generals joined the rebels or became their own bandit leaders.

Are there any other examples of such imperial drama in history?
 
Speaking for most americans I think I am sure I have no idea what you are talking about if you are concerning yourself with specific comparisons. I am the product of Eurocentrism on the topic of China. Ask me about the american continent or europe or the Near East but not China, ever...
So to answer your question in a general sense, I think just about every huge empire collapses in an interesting way. Alexander and the Roman empire's collapse are the first that come to mind. With Alexander you have the creation of new cultures seemingly out of no where. Hellenism spreading from India to Egypt. While the Roman empire's collapse creates the foundations of modern Nation states and changes language for centuries to come. Now if we take "interesting" in the Chineses sense, well I think china might have a monoply on the Chinese senses.
