Septinsular Republic
Originally widely welcomed, French rule began to grow oppressive to the islanders, and aroused the enmity of the Ottoman Empire and the Russian Empire. In 1798, a joint Russo-Ottoman campaign was launched against the islands, culminating in the four-month siege of Corfu. Its fall in March 1799 signalled the end of French rule, and the islands were reorganized as the Russo-Ottoman protectorate of the Septinsular Republic. The islands were again annexed to France in 1807 after the Treaty of Tilsit, but retained many of the institutions of the Septinsular Republic. The French were evicted from most of the islands by the British in 1809–10; only Corfu resisted until 1814. In 1815, the British established the United States of the Ionian Islands.
