Why is Northern Ireland part of the United Kingdom?

Economics separated it from Ireland, and will keep it separate for now

IT IS almost a year since riots hit the streets of Belfast last December. They were caused by a motion to limit the number of days Britain's Union Jack flag flew on Belfast City Hall. Severe rioting lasted for two months and seemed to centre on the tricky question of why Northern Ireland, composed of six north-eastern counties in Ireland, is part of the United Kingdom. The Northern Irish have their own flags, culture and international sports teams, but do not live in an independent country. Why?

Ireland became part of the United Kingdom in 1801. But Ireland’s sectarian divisions, which had opened up during religious wars in the 17th century between Protestants and Catholics, were exacerbated by economic problems in the 19th century. Britain’s shift to free trade from the 1840s onwards mainly benefited the industrial north-east of Ulster, where Protestants made up a majority of the population. But the rest of the country, which was more reliant on agriculture, suffered badly from falling global food prices and the Irish Famine of 1845-50. The result was the rise of Irish nationalist movements, drawing much of their support from the Catholic south, which wanted a new Irish Parliament and to re-introduce protectionist measures. When William Gladstone, then Britain’s prime minister, proposed Irish legislative independence (called Home Rule) in 1885, the north-east exploded with sectarian rioting against his proposals. Ulster Protestants feared that “Home Rule means Rome Rule”, thinking they would lose the religious and economic freedoms they enjoyed as part of the United Kingdom by becoming a minority in a mainly Catholic Ireland. When the rest of Ireland gained independence as the “Irish Free State” in 1922, north-east Ulster did not want to join them. The British government was forced to partition the six most north-eastern counties of the new Irish state to form Northern Ireland, in fear that Protestant civil unrest in Ulster would otherwise turn into a civil war against the new state.

Northern Ireland has since witnessed severe sectarian violence between its Protestant majority and its Catholic minority, particularly during the "Troubles" of 1968-98. The Good Friday Agreement, signed in 1998 sought to end that. The Republic dropped its claim to the North and London declared the status of Northern Ireland would be determined by wishes of its people. The deal was broadly a success, but friction has continued sporadically since then. Yet most people in Northern Ireland still seem to want to remain part of the United Kingdom. A BBC poll earlier this year suggested that just 17% of people in Northern Ireland want to leave the United Kingdom. Economic reasons may partly explain this. The Northern Irish economy has outperformed the rest of Ireland since 2007 and living costs are lower than in the south. According to a study last year by CEBR, an economic consultancy, Northern Ireland enjoys a net subsidy of 29.4% of its GDP each year from Britain, resulting in a better welfare state than in the south. While health care in the north is free under the NHS, a trip to the doctor costs most people up to €75 ($100) south of the border. Northern Ireland's (selective) grammar schools are highly regarded, though some of its other schools are bad.

The greatest threat to Northern Ireland’s place in the United Kingdom now comes from outside Ireland rather than within it. If Scotland votes for independence in a referendum due to be held in September 2014, what would happen to Northern Ireland? Its historic ties are to Scotland more than to England or Wales, but Scottish nationalists have thus far shown no interest in inheriting the province from the United Kingdom. Scottish independence might yet make Northern Ireland’s constitutional status a touchy subject again.
