Following France's defeat by Britain, Austria, Prussia, and Russia in 1814 and the subsequent 1815 Treaty of Paris, France was obligated to pay 700 million francs in reparations over five years and to host an Allied army of occupation. By 1818, France had met its payments punctually, creating grounds to renegotiate the remaining 332 million francs and discuss ending the occupation.
In autumn 1818, France and the four Allied powers convened at Aix-la-Chapelle to settle the remaining reparations and withdraw occupation forces. France offered to pay 265 million francs, partly in interest-bearing bonds, in lieu of the outstanding 332 million. The French representative Duc de Richelieu secured France's admission as a full partner in the European congress system, expanding the Concert of Four into a Concert of Five Powers.
The Congress formally ended the Allied military occupation of France by 30 November 1818, closed all financial claims arising from the Napoleonic Wars, and restored France as an equal member of the Concert of Europe. The Four Powers also secretly renewed the Quadruple Alliance as a precaution, though it proved inconsequential as they subsequently diverged over issues in Italy, South America, and Greece.
