The Guadeloupe Fund, or Guadeloupefonden, was established by the Riksdag of the Estates, of Sweden, in 1815 for the benefit of Crown Prince and Regent Charles XVI of Sweden, also known as Jean-Baptiste Bernadotte, and his heirs.
The background was that on March 3, 1813, the island of Guadeloupe was ceded by Great Britain to "His Royal Majesty the King of Sweden, and his successor to the Swedish throne according to the Act of Sucession of September 26, 1810" in order to keep the Crown Prince "at least partially compensated for the donations and other property, which he had lost as a since being called to the succession of the Swedish throne" and as a consequence of Swedens involvement in the Napoleonic Wars. Crown Prince Charles, or Jean-Baptiste Bernadotte, had been one of the most succesful soldiers in Napoleonic France. He was a Empire Marshal of France, a former minister of war and had been created Prince of Ponte Corvo by Napoleon, before accepting the election as heir to the Swedish throne. Under the powerless King Charles XIII of Sweden, his adoptive father, the Crown Prince was effectively the regent of the country and when Sweden sided with Napoleons enemies, Bernadotte came to be seen as a traitor to his native France. Upon Sweden's accession to the Sixth Coalition the offer of a West Indies island by Great Britain was an attept to in some way compensate for this. Guadeloupe was conveniently located in proximity to the Swedish colony of Saint-Barthélemy.
After France had been defeated and Nepoleon exiled to Elba, the Treaty of Paris of 1814 settled the terms of the peace, in which Guadeloupe, having earlier been a French possession, was returned to France. On August 13, 1814, a settlement of 24 million francs, was reached with Great Britain as a replacement for the intended compensation.
The sum of the settlement which came under the control of the Crown Prince, acting as regent, used about half of the sum to pay off Government debts and the rest going to various projects of public benefit. In recognition of this the Riksdag of 1815 instituted that the Crown Prince and his heirs would receive an annual installment of 300,000 Riksdaler, which was to be payed out in perpetuity.
