This is another museum piece of our collection. United States of Ionian Islands (1815-1864) was a British Protectorate of the British Empire having as common language the Venetian. 
Before the French Revolutionary Wars, the Ionian Islands had been part of the Republic of Venice. When the 1797 Treaty of Campo Formio dissolved the Republic of Venice, they were annexed to the French Republic. Between 1798 and 1799, the French were driven out by a joint Russo-Ottoman force.
After the War of the Fourth Coalition, the Ionian Islands were occupied by the French Empire as stipulated in the Treaty of Tilsit. In 1809, Britain defeated the French fleet off Zakynthos island on 2 October, and captured Kefalonia, Kythira, and Zakynthos. The British proceeded to capture Lefkada in 1810.
Under the Treaty between Great Britain and [Austria, Prussia and] Russia, respecting the Ionian Islands (signed in Paris on 5 November 1815), as one of the treaties signed during the Peace of Paris (1815), Britain obtained a protectorate over the Ionian Islands, and under Article VIII of the treaty the Austrian Empire was granted the same trading privileges with the Islands as Britain.
During this period, the British brought thousands of Maltese labourers to the Ionian Islands to work as builders and artisans, forming the basis of the Corfiot Maltese community.
A few years later Greek nationalist groups started to form. Although their energy in the early years was directed to supporting their fellow Greek revolutionaries in the revolution against the Ottoman Empire, they switched their focus to enosis with Greece following their independence. The Party of Radicals (Greek: Κόμμα των Ριζοσπαστών) was founded in 1848 as a pro-enosis political party. In September 1848, there were skirmishes with the British garrison in Argostoli and Lixouri on Kefalonia. The island's populace did not hide their growing demands for enosis, and newspapers on the islands frequently published articles criticising British policies in the protectorate. On 15 August 1849, another rebellion broke out, which was quashed by Henry George Ward, who proceeded to temporarily impose martial law.
On 26 November 1850, the Radical MP John Detoratos Typaldos proposed in the Ionian parliament the resolution for the enosis of the Ionian Islands with the Kingdom of Greece which was signed by Gerasimos Livadas, Nadalis Domeneginis, George Typaldos, Frangiskos Domeneginis, Ilias Zervos Iakovatos, Iosif Momferatos, Telemachus Paizis, Ioannis Typaldos, Aggelos Sigouros-Dessyllas, Christodoulos Tofanis. In 1862, the party split into two factions, the "United Radical Party" and the "Real Radical Party". During this period of British rule, William Ewart Gladstone visited the islands and recommended their reunion with Greece, to the chagrin of the British government.[citation needed]
On 29 March 1864, representatives of the United Kingdom, Greece, France, and Russia signed the Treaty of London, pledging the transfer of sovereignty to Greece upon ratification; this was meant to bolster the reign of the newly installed King George I of the Hellenes. Thus, on 28 May, by proclamation of the Lord High Commissioner, the Ionian Islands were united with Greece.
