The coming of Christianity from across the Irish Sea brought major changes and civilizing influences. Tradition maintains that St. Patrick arrived on the island in AD 432 and, in the years that followed, worked to convert the Irish to Christianity.
The pagan druid tradition collapsed before the spread of the new faith, and Irish scholars excelled in the study of Latin learning and Christian theology in the monasteries that flourished. Missionaries went forth from Ireland to England Great Britain and the continent, spreading news of the flowering of learning, and scholars from other nations came to Irish monasteries. The excellence and isolation of these monasteries helped preserve Latin and Greek learning during the Dark Ages. The arts of manuscript illumination, metalworking, and sculpture flourished and produced such treasures as the Book of Kells, ornate jewelry, and the many carved stone crosses that dot the island.
Two hundred years of Viking invasion and settlement was later followed by a Norman conquest in the 12th century. The Norman conquest resulted in the assimilation of the Norman settlers into Irish society. The early 17th century saw the arrival of Scottish and English Protestants, sent as colonists to the north of Ireland and the Pale around Dublin.
Nationalism was and is a potent populist force in Irish politics. A home rule bill passed in 1914, but its implementation was suspended until war in Europe ended. Believing the mantra: "England's problem is Ireland's opportunity," and tapping into a mood of Gaelic revivalism, Padraic Pearse and James Connolly led the unsuccessful Easter Rising of 1916. Pearse and the other 1916 leaders declared an independent Irish republic, but a lack of popular support doomed the rebellion, which lasted a week and destroyed large portions of Dublin. The decision by the British military government to execute the leaders of the rebellion, coupled with the British Government's threat of conscripting the Irish to fight in the Great War, alienated public opinion and produced massive support for Sinn Féin in the 1918 general election. Under the leadership of Eamon de Valera, the elected Sinn Féin deputies constituted themselves as the first Dail. Tensions only increased: British attempts to smash Sinn Féin ignited the Anglo-Irish War of 1919-1921.
The end of the war brought the Anglo-Irish treaty of 1921, which established the Irish Free State of 26 counties within the [[Commonwealth of Nations|British Commonwealth ]] and recognized the partition of the island into Ireland and Northern Ireland, though supposedly as a temporary measure. The six predominantly Protestant counties of northeast Ulster—Northern Ireland—remained a part of the United Kingdom with limited self-government. A significant Irish minority repudiated the treaty settlement because of the continuance of subordinate ties to the British monarch and the partition of the island. This opposition led to further hostilities—a civil war (1922–23), which was won by the pro-treaty forces. In 1932, Eamon de Valera, the political leader of the forces initially opposed to the treaty, became Prime Minister, and a new Irish constitution was enacted in 1937. The last British military bases were soon withdrawn, and the ports were returned to Irish control. Ireland was neutral in World War II. The government formally declared Ireland a republic in 1948; however, it does not normally use the term "Republic of Ireland," which tacitly acknowledges the partition, but refers to the country simply as "Ireland."
