Ireland became an English colony in the 12th century and in the first half of the 16th century it came under the domination of England. The politics that Britain adopted to maintain and strengthen its political and economic sovereignty and economic, political and intellectual freedoms that were seen in America and Europe initiated a revolutionary process that would lead to the liberation from the British sovereignty. The Ottoman Empire, which began to watch Ireland's independence struggle from the beginning of the 18th century, tried to learn the developments in the island and the Irish policies of England from the kaime (a kind of report) of Moldavian and Wallachian voivodes and the reports of diplomats in London. The Ottoman Empire regarded and watched these rebellions seen from the beginning of the 16th century as sectarian conflicts, small riots and revolutionary fire and except for humanitarian aids, avoided attempts that could harm the relations with England. Against the Irish independence demands, following harsh politics until the middle of the 19th century, English governments started to pursue reconciliatory politics from the 1880s onwards. As a result of negotiations, especially during periods when the Liberal Party was in power, Southern Ireland achieved its independence in 1921. In this article, the Irish revolutionary process starting at the end of the 17th century and culminating with the independence of Ireland in the 20th century and its relations with the Ottoman State will be examined in the light of Ottoman Archive documents and other sources.
