Through World War I and Constantinople

This agreement was the result of secret negotiations that took place earlier in 1878. The Convention was abrogated by the British on 5 November 1914, when Britain and the Ottoman Empire found themselves at war with each other following the Ottoman entry into World War I.

British administration established, 1878

The Sultan, Abdul Hamid II, ceded the administration of Cyprus to Britain, in exchange for guarantees that Britain would use the island as a base to protect the Ottoman Empire against possible Russian aggression. The British had been offered Cyprus three times (in 1833, 1841, and 1845) before accepting it in 1878.

In the mid-1870s, Britain and other European powers were faced with preventing Russian expansion into areas controlled by a weakening Ottoman Empire. Russia was trying to fill the power vacuum by expanding the Czar's empire west and south toward the warm water port of Constantinople and the Dardanelles. British administration of Cyprus was intended to forestall such an expansion. In June 1878, clandestine negotiations between Britain and the Porte culminated in the Cyprus Convention, by which "His Imperial Majesty the Sultan further consents to assign the island of Cyprus to be occupied and administered by England."

There was some opposition to the agreement in Britain, especially from Liberal leader William Ewart Gladstone. When Gladstone returned to power he did not return the island. Greek Cypriot nationalism made its presence known to the new rulers, when, in a welcoming speech at Larnaca for the first British High Commissioner to Cyprus, the bishop of Kition expressed the hope that the British would expedite the unification of Cyprus and Greece as they had previously done with the Ionian Islands. Thus, the British were confronted at the very beginning of their administration with the reality that enosis was vital to many Greek Cypriots.

The island served Britain as a key military base on the sea route to British India, which was then Britain's most important overseas possession. In 1906, a new harbour at Famagusta was completed, increasing the importance of Cyprus as a strategic naval outpost protecting the approaches to the Suez Canal. Early in the First World War the Ottoman Empire joined the Central Powers, and on 5 November 1914 Britain annexed Cyprus, bringing an end to the Convention following the Ottoman entry into World War I.
