The Congress of Vienna set the terms of the peace settlement that ended twenty years of war against France. It established the framework of a balance of power between the major European states that lasted, in broad terms, until 1914. In Vienna, and at subsequent congresses, measures to fend off liberal and nationalist attacks on the socio-political conservative status quo were initiated. In the short run, many of the administrative institutions and political practices of the Old Regime were restored and protected by international military interventions.
