Concert of Europe
Concert of Europe, in the post-Napoleonic era, the vague consensus among the European monarchies favouring preservation of the territorial and political status quo. The term assumed the responsibility and right of the great powers to intervene and impose their collective will on states threatened by internal rebellion. The powers notably suppressed uprisings in Italy (1820) and Spain (1822) but later condoned Belgium’s rebellion and proclamation of independence (1830).
