In 3000 BC, immigrants from mainland Europe began to settle on the island of Ireland. In 432 AD, Saint Patrick came here to spread Christianity and Roman culture. Entered feudal society in the 12th century. It was invaded by the British in 1169. In 1171, King Henry II of England established his authority over Love. From 1541 the King of England became King of Ireland. In 1800, the Irish-British Alliance Treaty was signed, establishing the United Kingdom of Great Britain and Ireland, which was completely annexed by the United Kingdom. In 1916, the "Easter Rising" against the British broke out in Dublin. With the rise of the Irish national independence movement, the British government signed the Anglo-Irish Treaty with Ireland in December 1921, allowing 26 counties in southern Ireland to establish a "Free State" and enjoy autonomy. The six northern counties (now Northern Ireland) remain part of the United Kingdom. In 1937, the Irish Constitution declared the "Free State" to be a republic but remained within the Commonwealth. On December 21, 1948, the Irish Parliament passed a law declaring its separation from the Commonwealth. On April 18, 1949, Britain recognized its independence but refused to return the six northern counties. After Ireland became independent, successive Irish governments have made it their established policy to achieve the unification of Northern and Southern Ireland.
