Historical Trajectory
Phase I: Rise
A joint Russo-Ottoman naval expedition expelled French Republican forces from the Ionian Islands in 1799–1800, ending two years of French rule imposed after the Treaty of Campo Formio. The resulting Constitutional Charter of 1800 established the Septinsular Republic as an autonomous oligarchic state, tributary to the Ottoman Porte but effectively under Russian dominance—and for the first time since the 15th century, Greeks exercised formal self-government.
Phase II: Zenith
During its brief existence the republic operated under a written constitution and a locally elected senate drawn from the islands' noble families. The Ionian Islands maintained their existing legal traditions blending Venetian and Greek elements. Corfu functioned as the administrative and cultural center, and the republic's governmental framework represented a notable experiment in Hellenic civic institutions under external sponsorship.
Phase III: Decline
The Treaties of Tilsit in 1807 led Napoleon and Tsar Alexander I to agree on a reallocation of territories; France received the Ionian Islands, ending the republic. Although local institutions were temporarily preserved under French rule, British naval pressure steadily displaced France from 1809 onward. The Congress of Vienna and the Treaty of Paris (1815) formally reorganized the islands as the United States of the Ionian Islands under British protection.
