Irish nationalism is a nationalist political movement which, in its broadest sense, asserts that the people of Ireland should govern Ireland as a sovereign state. Since the mid-19th century, Irish nationalism has largely taken the form of cultural nationalism based on the principles of national self-determination and popular sovereignty. Irish nationalists during the 18th, 19th, and 20th centuries such as the United Irishmen in the 1790s, Young Irelanders in the 1840s, the Fenian Brotherhood during the 1880s, Fianna Fáil in the 1920s, and Sinn Féin styled themselves in various ways after French left-wing radicalism and republicanism. Irish nationalism celebrates the culture of Ireland, especially the Irish language, literature, music, and sports. It grew more potent during the period in which all of Ireland was part of the United Kingdom, which led to most of the island gaining independence from the UK in 1922. Irish nationalists believe that foreign English and later rule in Ireland from 1169 the English Norman Invasion of Ireland onwards has been detrimental to Irish interests. At the time of the partition of Ireland most of the island was Roman Catholic and largely indigenous, while a sizeable portion of the country, particularly in the north, was Protestant and chiefly descended from people from Great Britain who colonised the land as settlers during the reign of King James I in 1609. Partition was along these ethno-religious lines, with most of Ireland gaining independence, while six northern counties remained part of the United Kingdom. Irish nationalists now support Irish reunification with a unified secular state. History Early development Generally, Irish nationalism is regarded as having emerged following the Renaissance revival of the concept of the patria and the religious struggle between the ideology of the Protestant Reformation and the Catholic Counter-Reformation. At this early stage in the 16th century, Irish nationalism represented an ideal of the native Gaelic Irish and the Old English banding together in common cause, under the banner of Catholicism and Irish civic identity ("faith and fatherland/motherland"), hoping to protect their land and interests from the New English Protestant forces sponsored by England. This vision sought to overcome the old ethnic divide between Gaeil (the native Irish) and Gaill (the Normans) which had been a feature of Irish life since the 12th century, following the Norman invasion of Ireland. Protestantism in England introduced a religious element to the 16th-century Tudor conquest of Ireland, as many of
