GEORGE IV, as Regent (1762-1830). King of England.
Document Signed ('George PR' at the head), 1¼ pages folio, Carlton House, 11 April 1816. Countersigned by the Foreign Secretary, Viscount Castlereagh. Ordering the Lord Chancellor, Baron Eldon, to affix the Great Seal to the Accession of the Grand Duke of Saxony, Weimar and Eisenach to the general treaty agreed at the Congress of Vienna.
The Congress of Vienna met from 1 October 1814 until 9 June 1815 with a brief fillip during Napoleon's hundred days. Britain, Austria, Russia, and Prussia, as members of the victorious quadruple alliance, made substantial territorial gains although not without diplomatic wrangling over the map of central Europe.
Another fruit of Vienna was the congress system in which members of the alliance arranged regular diplomatic meetings. The system, which was intended to defuse hostile situations and peacefully resolve disputes, ultimately collapsed as member countries pursued separate national interests.
