British Cyprus refers to the island of Cyprus under the dominion of the British Empire, administered sequentially from 1878 to 1912 as a British Protectorate, a unilaterally annexed military occupation from 1914 to 1922 and from 1922 to 1960 as a Crown colony.
Cyprus was a territory of the Ottoman Empire, lastly as part of the Vilayet of the Archipelago, since it was conquered from the Republic of Venice in 1570-71.
A British protectorate under Ottoman suzerainty was established over Cyprus by the Cyprus Convention of 4 June 1878, following the Russo-Turkish War, in which the British occupied the island as a consequence of the Ottoman Empire's actions throughout the duration of the war. Cyprus was then proclaimed a British protectorate and was integrated into the British Empire. This remained in place until November 1914, when after the Ottomans joined the Central Powers, in turn entering World War I, Britain declared the complete annexation of Cyprus into the British Empire, albeit under a military administration status. The colony of British Cyprus was proclaimed a decade later, in 1925, after Britain's annexation of Cyprus was verified twice, firstly in the Treaty of Sevres in 1920, then confirmed again in the Treaty of Lausanne in 1923.
Signed on 19 February 1959, the London and Zurich Agreements started the process for the constitution of an independent Cyprus. The United Kingdom granted independence of Cyprus via referendum on 16 August 1960 and formed the Republic of Cyprus. Archbishop Makarios III, a charismatic religious and political leader, was elected the first president of independent Cyprus. In 1961 the Republic of Cyprus became the 99th member of the United Nations.
