The Congress of Vienna occurred because political leaders feared that enhanced national consciousness and notions of popular sovereignty would cause more revolts and uprisings. The nations represented at the congress were Russia, Prussia, Austria, and Britain. Napoleon's empire was taken apart, sovereignty was re-established, and a diplomatic order based on balance of power was founded. However, the Congress' efforts has limited success since the balance of power didn't last when global war occurred and methods such as censorship were used to suppress revolution. Essentially, by this point in time the flame of nationalism was impossible to extinguish.
