The United States of the Ionian Islands was a Greek state and amical protectorate of the United Kingdom between 1815 and 1864. The successor state of the Septinsular Republic, it covered the territory of the Ionian Islands, as well as the port of Parga on the Greek mainland. It was ceded by the British to Greece as a gift to the newly enthroned King George I, apart from Parga, which had been sold to Ali Pasha of Ioannina in 1819.
