CEVAP:

The Concert of Europe is often provided as a prominent example of great power management. The Congress of Vienna consolidated the great-power status of some states. Following the Congress, the powers of the time, namely Britain, Russia, Austria, Prussia and France, were remembered as great powers for the next hundred years, and the concert of these powers ruled the world. These great powers restored the European state system, in which many independent and sovereign states acted without any fear of conquest. This concert has been appreciated because it also prevented a general war in Europe from 1815 to 1914 (Wight, 1978: 41-43, Palmer, Colton, and Kramer, 2007: 430-431).
