To which group of islands does Corfu belong?

Corfu is a Greek island in the Ionian Sea. It is the second largest of the Ionian Islands, and, including its small satellite islands, forms the northwestern most part of Greece. The principal city of the island and seat of the municipality (pop. 32,095) is also named Corfu.

By the 1797 Treaty of Campo Formio, Corfu was ceded to the French, who occupied it for two years as the département of Corcyre, until they were expelled by a joint Russian-Ottoman squadron under Admiral Ushakov. For a short time it became the capital of a self-governing federation of the Heptanesos ("Seven Islands"), under Ottoman suzerainty; in 1807 after the Treaty of Tilsit its faction-ridden government was again replaced by a French administration under governor François-Xavier Donzelot, and in 1809 it was besieged in vain by a British fleet, which had taken all the other Ionian islands.

The Ionian Islands became a protectorate of the United Kingdom by the Treaty of Paris of 5 November 1815 as the United States of the Ionian Islands. Corfu became the seat of the British Lord High Commissioner of the Ionian Islands. The period of British rule was a prosperous period for Corfu because the Greek language became official, new roads were built, the water supply system was improved and the first Greek university was founded in 1824.

Corfu is a very popular tourist destination. The island was the location of the 1994 European Union summit.
