Explanation:

Concert of Europe

Concert of Europe was a grouping of  European powers including Russia, Prussia, Austria and the United Kingdom. These states had earlier defeated Napolean by forming a Quadruple Alliance in 1815. France later became its member after the restoration of Bourbon monarchy. The system collapsed after the Revolution of 1848. In 1871 German Chancellor Otto von Bismarck restored the system to avoid future conflicts in Europe. This system continued till  the beginning of World War I in 1914 when the Concert of Europe split into the Triple Alliance and the Triple Entente.
