When the British took over Cephalonia in 1809, they proclaimed, "We present ourselves to you, Inhabitants of Cephalonia, not as invaders, with views of conquest, but as allies who hold forth to you the advantages of British protection." When the British continued to occupy the Ionian Islands after the Napoleonic wars, they did not formally annex the islands, but described them as a protectorate. The islands were constituted by the Treaty of Paris in 1815 as the independent United States of the Ionian Islands under British protection. Similarly, Malta was a British protectorate between the capitulation of the French in 1800 and the Treaty of Paris of 1814.
The princely states of India was another example of how indirect rule was used during the time of Empire. So too were many of the West African holdings.
Other British protectorates followed. In the Pacific Ocean the sixteen islands of the Gilberts (now Kiribati) were declared a British Protectorate by Captain Davis R.N., of HMS Royalist between 27 May and 17 June 1892. The Royalist also visited each of the Ellice Islands, and Captain Davis was requested by islanders to raise the British flag, but he did not have instructions to declare the Ellice Islands as a protectorate. The nine islands of the Ellice Group (now Tuvalu) were declared a British Protectorate by Captain Gibson R.N., of HMS Curacoa, between 9 and 16 October of the same year. Britain defined its area of interest in the Solomon Islands in June 1893, when Captain Gibson R.N., of HMS Curacoa, declared the southern Solomon Islands as a British Protectorate with the proclamation of the British Solomon Islands Protectorate.
In 1894, Prime Minister William Ewart Gladstone's government officially announced that Uganda, where Muslim and Christian strife had attracted international attention, was to become a British Protectorate. The British administration installed carefully selected local kings under a program of indirect rule through the local oligarchy, creating a network of British-controlled civil service. Most British protectorates were overseen by a Commissioner or a High Commissioner, rather than a Governor.
British law makes a distinction between a protectorate and a protected state. Constitutionally the two are of similar status, in which Britain provides controlled defence and external relations. However, a protectorate has an internal government established, while a protected state establishes a form of local internal self-government based on the already existing one.
Persons connected with a former British protectorate, protected state, mandated territory or trust territory may remain British Protected Persons if they did not acquire the nationality of the country at independence.
The last British protectorate proper was the British Solomon Islands, now Solomon Islands, which gained independence in 1978; the last British protected state was Brunei, which gained full independence in 1984.
