Following France's defeat in the Napoleonic Wars and the 1815 Treaty of Paris, the Allied powers imposed an army of occupation on French soil and required reparations of 700 million francs payable in installments over five years. By 1818, France had met its scheduled payments punctually, leaving 332 million francs outstanding, prompting negotiations over early settlement and troop withdrawal.
Meeting in the autumn of 1818, representatives of France, Britain, Austria, Prussia, and Russia convened at Aix-la-Chapelle to negotiate the end of the occupation and refinance the remaining reparations debt. France offered to settle 265 million francs through a combination of interest-bearing bonds and installments paid through English banks, which the Allies accepted. The French representative Duc de Richelieu also secured France's admission as a full partner in the Concert of Europe.
All Allied troops withdrew from France by 30 November 1818, definitively closing claims arising from the wars of 1792–1815. France was restored as an equal great power within what became a Concert of Five. The Four Allies secretly renewed the Quadruple Alliance as a precaution, but the grouping gradually fragmented over disputes concerning Italy, South America, and Greece.
Political Outcome
France's occupation ended, reparations were refinanced at reduced terms, and France was admitted as a full member of the Concert of Europe, expanding it from four to five powers.
France under Allied occupation with reparations obligations; Concert of Four great powers
France restored as equal great power; Concert of Europe expanded to Five Powers
