Such were the general tendencies of European politics when the conference of Aix-la-Chapelle assembled on September 30, 1818. The primary object of this conference was to consider the request of France for a reduction in the indemnity demanded of her and for the evacuation of her territories by the four allied powers. Wellington and Castlereagh, who represented Great Britain, earned the gratitude of France by readily agreeing to these requests, which were granted without any difficulty. This question was obviously one which required such a conference to settle it; but the conference, having once assembled, was urged to deal with other difficulties that less directly concerned it. One of these was a dispute between Denmark and Sweden about the apportionment of the Danish debt, which, in consideration of the annexation of Norway to Sweden, under the treaty of Kiel, was to be partly borne by Sweden. Denmark appealed to the four powers, representing that treaty as in fact a part of their own settlement of Europe. Sweden would not admit the right of the powers to intervene, but finally settled her difficulty with Denmark by a separate negotiation conducted by the mediation of Great Britain in 1819. A still more doubtful question was raised by the request of Spain for the assistance of the allied powers against her revolted colonies. The Spanish dependencies in America had declined to acknowledge Joseph Bonaparte, and had lapsed into a state of chaos; the restoration of Ferdinand VII. had induced most of them to return to their allegiance, but the three south-eastern colonies, Banda Oriental (Uruguay), La Plata (the Argentine), and Paraguay, continued in revolt. In 1817 fortune turned still further against Spain; Monte Video, the capital of Banda Oriental, was taken by Portugal, or rather by Brazil, and Chile revolted against Spain. On February 12, 1818, Chile proclaimed her independence, and she began at once to procure warships in England and the United States, of which Lord Cochrane took command. The four allied powers and France had protested against the seizure of Monte Video, but otherwise Spain had been left to herself. Great Britain seemed to have more to gain than to lose by the insurrection. The revolted colonies were open to her commerce, and by weakening Spain they had strengthened the maritime supremacy of Great Britain. Nevertheless Great Britain was willing to mediate, on condition that Spain would make reasonable concessions. Spain, however, refused to make any concessions at all, and called on the allied powers to aid her in crushing the insurrection by force. Great Britain did not regard an unconditional subjection of the colonies as either expedient or practicable, and opposed this course; Austria took the same view, and thus placed intervention out of the question.
