Hi!

I edited it for You; it seems to me that you copied things twice, so here is the edit:

Which is the correct order of events that eventually led to the collapse of the Chinese imperial government?

rise of nationalism,
Opium Wars,
Taiping Rebellion,
Boxer Rebellion
 

now, let's see when they happened:

 
Opium Wars, 1839–1842, then another starting in 1856 and another lated
Taiping Rebellion, 1850 to 1864
Boxer Rebellion  1899 and 1901

So the order of those three is:

Opium Wars,
Taiping Rebellion,
Boxer Rebellion

now, the timeline of nationalism is more difficult, as China had many waves of nationalism. But before 20th century nationalism referred to Han tribe, rather than Chinese, so I'd put it after all three events, as the last event.
