For a short time, Corsica was a protectorate of King George III, chiefly by the exertions of Hood's fleet (e.g. in the Siege of Calvi), and Paoli's co-operation. This period has become known as the "Anglo-Corsican Kingdom" because George III was accepted as sovereign head of state, but this was not an incorporation of Corsica into the British Empire. The relationship between Paoli's government and the British was never clearly defined, resulting in numerous questions of authority. At last the crown invited Paoli to resign and return to exile in Britain with a pension, which, having no other options now, he did. Not long after, the French reconquered the island and all questions of Corsican sovereignty came to an end until the 20th century.
