The 1815 peace treaties were drawn up entirely in
French, the
lingua franca of contemporary diplomacy. There were four treaties, between France and each of the four major
Seventh Coalition powers: Austria, Great Britain, Prussia and Russia. All four treaties were signed on the same day (20 November 1815), had verbatim stipulations, and were styled the same way (for example the "Definitive Treaty between Great Britain and France"). Thanks to Castlereagh, who now occupied the dominant position that had been held by the Tsar of Russia in 1814, and whose primary concern was to avoid the alienation of the French toward the restored Bourbons, the treaty of 1815 was only moderately harsher than the
Treaty of 1814, which had been negotiated through the manoeuvre of
Talleyrand. With the new treaty, France lost the territorial gains of the
Revolutionary armies in 1790–1792, which the previous treaty had allowed France to keep; the nation was reduced to its 1790 boundaries, plus the enclaves of the
Comtat Venaissin, the
County of Montbéliard and the
Republic of Mulhouse, which France was allowed to keep, but minus a few patches of territory along the northern border, including the former
duchy of Bouillon, annexed to France 1795,
Landau and the
Saarlouis exclave, which had been French since 1697, as well as six communes in the
Pays de Gex which were ceded to the
Canton of Geneva so that it be connected to the rest of Switzerland. France was now also ordered to pay 700 million francs in indemnities, in five yearly instalments, and to maintain at its own expense a Coalition army of occupation of 150,000 soldiers in the eastern border territories of France, from the
English Channel to the border with Switzerland, for a maximum of five years. The twofold purpose of the military occupation was rendered self-evident by the convention annexed to the treaty outlining the incremental terms by which France would issue negotiable bonds covering the indemnity: in addition to safeguarding the neighboring states from a revival of revolution in France, it guaranteed fulfilment of the treaty's financial clauses. The treaty was signed for
Great Britain by
Robert Stewart, Viscount Castlereagh and the Duke of Wellington and by
Armand-Emmanuel du Plessis, Duc de Richelieu for France; parallel treaties with France were signed by
Austria,
Russia, and Prussia, forming in effect the first
confederation of Europe. The
Quadruple Alliance was reinstated in a separate treaty also signed 20 November 1815, introducing a new concept in European diplomacy, the peacetime congress "for the maintenance of peace in Europe" on the pattern of the
Congress of Vienna, which had concluded 9 June 1815. The treaty is brief. In addition to having "preserved France and Europe from the convulsions with which they were menaced by the late enterprise of Napoleon Bonaparte", whereby the treaty became a part of the public law by which Europe, with the exclusion of the
Ottoman Empire, established "relations from which a system of real and permanent
balance of power in Europe is to be derived".
Article on the slave trade An additional article appended to the treaty addressed the issue of
slavery. It reaffirmed the
Declaration of the Powers, on the Abolition of the Slave Trade, of 8th of February 1815 (which also formed
ACT, No. XV. of the Final Act of the
Congress of Vienna) and added that the governments of the contracting parties should "without loss of time, ... [find] the most effectual measures for the entire and definitive abolition of a Commerce so odious, and so strongly condemned by the laws of religion and of nature". ==Convention on pecuniary indemnity==
