Counterexamples: fall of the Soviet Union, the fall of the Fourth Republic in France in 1954, English Civil War and the English royal restoration a few decades later.
Well, I guess the GP should have added "the government stupidly mass-murdering its citizens at random" to the other 3 causes.
About the fall of the Soviet Union, a lot of it was caused by each one of the GP's factors and the mass-murdering. You seem to want a clear case with a well defined "fall", but theirs wasn't it (like any supranacional empire).
All other issues people will complain about, but never act on en-mass.
