Congress of Vienna The Congress of Vienna ( ) was a conference of ambassadors of European states chaired by Austrian statesman Klemens Wenzel von Metternich , and held in Vienna from September 1814 to June 1815 . The objective of the Congress was to settle the many issues arising from the French Revolutionary Wars , the Napoleonic Wars , and the dissolution of the Holy Roman Empire . This objective resulted in the redrawing of the continent ' s political map , establishing the boundaries of France , the Duchy of Warsaw , the Netherlands , the states of the Rhine , the German Kingdom of Saxony , and various Italian territories , and the creation of spheres of influence through which Austria , Britain , France and Russia brokered local and regional problems . The Congress of Vienna was the first of a series of international meetings that came to be known as the Concert of Europe , which was an attempt to forge a peaceful balance of power in Europe , and served as a model for later organizations such as the League of Nations and United Nations . The immediate background was Napoleonic France ' s defeat and surrender in May 1814 , which brought an end to twenty - five years of nearly continuous war . Negotiations continued despite the outbreak of fighting triggered by Napoleon ' s dramatic return from exile and resumption of power in France during the Hundred Days of March – July 1815 . The Congress ' s " Final Act " was signed nine days before his final defeat at Waterloo on 18 June 1815 . In a technical sense , the " Congress of Vienna " was not properly a Congress : it never met in plenary session , and most of the discussions occurred in informal , face - to - face , sessions among the Great Powers of Austria , France , Russia , the United Kingdom and sometimes Prussia , with limited or no participation by other delegates . On the other hand , the Congress was the first occasion in history where , on a continental scale , national representatives came together to formulate treaties , instead of relying mostly on messengers and messages between the several capitals . The Congress of Vienna settlement , despite later changes , formed the framework for European international politics until the outbreak of the First World War in 1914 . Preliminaries . Partial settlements had already occurred at the Treaty of Paris between France and the Sixth Coalition , and the Treaty of Kiel which covered issues raised regarding Scandinavia . The Treaty of Paris had determined that a " general congress " should be held in Vienna , and that invitations would be issued to " all the Powers engaged on either side in the present war . " The opening was scheduled for July 1814 . Participants . The Four Great Powers and Bourbon France . The Four Great Powers had previously formed the core of the Sixth Coalition . On the verge of Napoleon ' s defeat they had outlined their common position in the Treaty of Chaumont ( March 1814 ) , and negotiated the Treaty of Paris ( 1814 ) with the Bourbons during their restoration : The other signatories of the Treaty of Paris , 1814 . These parties had not been part of the Chaumont agreement , but had joined the Treaty of Paris ( 1814 ) : Others . Virtually every state in Europe had a delegation in Vienna – more than 200 states and princely houses were represented at the Congress . In addition , there were representatives of cities , corporations , religious organizations ( for instance , abbeys ) and special interest groups – e . g . , a delegation representing German publishers , demanding a copyright law and freedom of the press . The Congress was noted for its lavish entertainment : according to a famous joke it did not move , but danced . Course of the Congress . Initially , the representatives of the four victorious powers hoped to exclude the French from serious participation in the negotiations , but Talleyrand skillfully managed to insert himself into " her inner councils " in the first weeks of negotiations . He allied himself to a Committee of Eight lesser powers ( including Spain , Sweden , and Portugal ) to control the negotiations . Once Talleyrand was able to use this committee to make himself a part of the inner negotiations , he then left it , once again abandoning his allies . The major Allies ' indecision on how to conduct their affairs without provoking a united protest from the lesser powers led to the calling of a preliminary conference on protocol , to which Talleyrand and the Marquis of Labrador , Spain ' s representative , were invited on 30 September 1814 . Congress Secretary Friedrich von Gentz reported , " The intervention of Talleyrand and Labrador has hopelessly upset all our plans . Talleyrand protested against the procedure we have adopted and soundly [ be ] rated us for two hours . It was a scene I shall never forget . " The embarrassed representatives of the Allies replied that the document concerning the protocol they had arranged actually meant nothing . " If it means so little , why did you sign it ? " snapped Labrador . Talleyrand ' s policy , directed as much by national as personal ambitions , demanded the close but by no means amicable relationship he had with Labrador , whom Talleyrand regarded with disdain . Labrador later remarked of Talleyrand : " that cripple , unfortunately , is going to Vienna . " Talleyrand skirted additional articles suggested by Labrador : he had no intention of handing over the 12 , 000 " afrancesados " – Spanish fugitives , sympathetic to France , who had sworn fealty to Joseph Bonaparte ( with whom he had unscrupulous business connections ) – nor the bulk of the documents , paintings , pieces of fine art , and works of hydrography and natural history that had been looted from the archives , palaces , churches and cathedrals of Spain . Final Act . The Final Act , embodying all the separate treaties , was signed on 9 June 1815 ( a few days before the Battle of Waterloo ) . Its provisions included : The Final Act was signed by representatives of Austria , France , Portugal , Prussia , Russia , Sweden - Norway , and the United Kingdom . Spain did not sign the treaty but ratified it in 1817 . Polish - Saxon crisis . The most controversial subject at the Congress was the so - called Polish - Saxon Crisis . The Russians and Prussians proposed a deal in which much of the Prussian and Austrian shares of the partitions of Poland would go to Russia , which would create a Polish Kingdom in personal union with Russia and Alexander as king . In compensation , the Prussians would receive all of Saxony , whose King was considered to have forfeited his throne as he had not abandoned Napoleon soon enough . The Austrians , French , and British did not approve of this plan , and , at the inspiration of Talleyrand , signed a secret treaty on 3 January 1815 , agreeing to go to war , if necessary , to prevent the Russo - Prussian plan from coming to fruition . Though none of the three powers was ready for war , the Russians did not call the bluff , and an amicable settlement was set on 24 October 1815 , by which Russia received most of the Napoleonic Duchy of Warsaw as a " Kingdom of Poland " – called Congress Poland – but did not receive the district of Poznań , Grand Duchy of Poznań , which was given to Prussia , nor Kraków , which became a free city . Prussia received 40 % of Saxony – later known as the Province of Saxony , with the remainder returned to King Frederick Augustus I – Kingdom of Saxony . Other changes . The Congress ' s principal results , apart from its confirmation of France ' s loss of the territories annexed between 1795 – 1810 , which had already been settled by the Treaty of Paris , were the enlargement of Russia , ( which gained most of the Duchy of Warsaw ) and Prussia , which acquired Westphalia and the northern Rhineland . The consolidation of Germany from the nearly 300 states of the Holy Roman Empire ( dissolved in 1806 ) into a much more manageable thirty - nine states ( 4 of which were free cities ) was confirmed . These states were formed into a loose German Confederation under the leadership of Prussia and Austria . Representatives at the Congress agreed to numerous other territorial changes . By the Treaty of Kiel , Norway had been ceded by the king of Denmark - Norway to the king of Sweden . This sparked the nationalist movement which led to the establishment of the Kingdom of Norway on May 17 , 1814 and the subsequent personal Union with Sweden . Austria gained Lombardy - Venetia in Northern Italy , while much of the rest of North - Central Italy went to Habsburg dynasties ( the Grand Duchy of Tuscany , the Duchy of Modena , and the Duchy of Parma ) . The Papal States were restored to the Pope . The Kingdom of Piedmont - Sardinia was restored to its mainland possessions , and also gained control of the Republic of Genoa . In Southern Italy , Napoleon ' s brother - in - law , Joachim Murat , was originally allowed to retain his Kingdom of Naples , but his support of Napoleon in the Hundred Days led to the restoration of the Bourbon Ferdinand IV to the throne . A large United Kingdom of the Netherlands was created for the Prince of Orange , including both the old United Provinces and the formerly Austrian - ruled territories in the Southern Netherlands . There were other , less important territorial adjustments , including significant territorial gains for the German Kingdoms of Hanover ( which gained East Frisia from Prussia and various other territories in Northwest Germany ) and Bavaria ( which gained the Rhenish Palatinate and territories in Franconia ) . The Duchy of Lauenburg was transferred from Hanover to Denmark , and Swedish Pomerania was annexed by Prussia . Switzerland was enlarged , and Swiss neutrality was established . Swiss mercenaries had played a significant role in European Wars for a couple of hundred years , and the intention was to put a stop to these activities permanently . During the wars , Portugal had lost its town of Olivença to Spain and moved to have it restored . Portugal is historically the oldest ally of the United Kingdom , and with its support succeeded in having the re - incorporation of Olivença decreed in Article 105 of the Final Act , which stated that the Congress " understood the occupation of Olivença to be illegal and recognized Portugal ' s rights " . Portugal ratified the Final Act in 1815 but Spain would not sign and this became the most important hold - out against the Congress of Vienna . Deciding in the end that it was better to become part of Europe than stand alone , Spain finally accepted the Treaty on 7 May 1817 ; however , Olivença and its surroundings were never returned to Portuguese control and this question remains unresolved . The United Kingdom of Great Britain and Ireland received parts of the West Indies at the expense of the Netherlands and Spain and kept the former Dutch colonies of Ceylon and the Cape Colony as well as Malta and Heligoland . Under the Treaty of Paris , Britain obtained the protectorate over the United States of the Ionian Islands and the Seychelles . Later criticism . The Congress of Vienna was frequently criticized by nineteenth - century and more recent historians for ignoring national and liberal impulses , and for imposing a stifling reaction on the Continent . It was an integral part in what became known as the Conservative Order , in which the liberties and civil rights associated with the American and French Revolution s were de - emphasized , so that a fair balance of power , peace and stability , might be achieved . In the 20th century , however , many historians came to admire the statesmen at the Congress , whose work prevented another widespread European war for nearly a hundred years ( 1815 – 1914 ) . Among these is Henry Kissinger , who in 1954 wrote his doctoral dissertation , " A World Restored " , on it . Prior to the opening of the Paris peace conference of 1918 , the British Foreign Office commissioned a history of the Congress of Vienna to serve as an example to its own delegates of how to achieve an equally successful peace . Besides , the main decisions of the Congress were made by the Four Great Powers and not all the countries of Europe could extend their rights at the Congress . The Italian peninsula became a mere " geographical expression " as divided into seven parts : Lombardy – Venetia , Modena , Naples – Sicily , Parma , Piedmont – Sardinia , Tuscany , and the Papal States under the control of different powers . Poland remained partitioned between Russia , Prussia and Austria , with the largest part , the newly created Kingdom of Poland , remaining under Russian control . The arrangements made by the Four Great Powers sought to ensure future disputes would be settled in a manner that would avoid the terrible wars of the previous twenty years . Although the Congress of Vienna preserved the balance of power in Europe , it could not check the spread of revolutionary movements across the continent some 30 years later .
