Republic of Ireland–United Kingdom border
Originally intended as an internal boundary within the United Kingdom of Great Britain and Ireland, the border was created in 1921 under the United Kingdom Parliament's Government of Ireland Act 1920. Prior to this, a separatist Irish parliament had been established in Dublin, which did not recognise the Government of Ireland Act, and was actively engaged in the Irish War of Independence. The Act was intended to deliver Home Rule in Ireland, with separate parliaments for Southern Ireland (which included three of the nine counties of Ulster) and Northern Ireland. Six of the thirty-two counties of Ireland were assigned to Northern Ireland, and the rest of Ireland comprising 26 counties to Southern Ireland.
History of Ireland
On 1 January 1801, in the wake of the republican United Irishmen Rebellion, the Irish Parliament was abolished and Ireland became part of a new United Kingdom of Great Britain and Ireland formed by the Acts of Union 1800. Catholics were not granted full rights until Catholic Emancipation in 1829, achieved by Daniel O’Connell. The catastrophe of the Great Famine struck Ireland in 1845 resulting in over a million deaths from starvation and disease and in a million refugees fleeing the country, mainly to America. Irish attempts to break away continued with Parnells Irish Parliamentary Party which strove from the 1880s to attain Home Rule through the parliamentary constitutional movement, eventually winning the Home Rule Act 1914, although this Act was suspended at the outbreak of World War I.
