United States of the Ionian Islands took Lefkada in 1810. The island of Corfu remained occupied by the French until 1814. The Congress of Vienna agreed to place the Ionian Islands under the exclusive "amical protection" of the United Kingdom. Despite British military administration, the Austrian Empire was guaranteed commercial status equal to the UK.

The Party of Radicals (Greek: Κόμμα των Ριζοσπαστών) founded in 1848 was against the
