France received de jure control of the island of Corsica as a pledge from the Genoese Republic via the Treaty of Versailles in 1768. Genoa still claimed ownership of the island, although since 1755, Corsicans had achieved virtual independence and had written a Corsican Constitution (in Italian). After abandoning any hope of recovering Corsica by force, the Genoese chose to sell their rights over the island to France who were keen to gain new territory to replace territory lost during the Seven Years' War.
