The Concert of Europe was formulated in 1815 as a mechanism to enforce the decisions of the Congress of Vienna. Composed of the Quadruple Alliance: Russia, Prussia, Austria, and Great Britain, its main priorities were to establish a balance of power, thereby preserving the territorial status quo, and to protect "legitimate" governments. Headed by Prince
Metternich of Austria, the Concert of Europe was one of the first serious attempts in modern times to establish an international society to maintain the peace. This made it a significant event in world history, even though it only lasted for a few decades.
