What valuable lesson did the French Revolution teach the world about democracy and government? Name two examples of more modern governments.

To me, the valuable lesson taught by the French Revolution is that unbridled democracy and unlimited government are dangerous.

During the French Revolution, the revolutionaries unleashed a hellish system where anyone they disliked was likely to be executed.  There was no real system of checks and balances or of personal liberties.  There was no protection against excessive government power.

Because they failed to rein in democracy and the power of the government, the French revolutionaries were unable to create a lasting and stable government.  This shows us that stable democratic governments need to be limited so they will not go overboard and abuse those that the majority dislike.
