Congress of Verona

The Congress of Verona met at Verona on 20 October 1822 as part of the series of international conferences or congresses that opened with the Congress of Vienna in 1814–15, which had instituted the Concert of Europe at the close of the Napoleonic Wars.

While the representatives of the United Kingdom and the European powers had at first, during the Congress of Vienna, acted largely in concert, the extent to which the concord epitomized in the expression the "Concert of Europe" had unraveled in seven years became apparent in the way in which the three main questions before this Congress were handled.
