The dialect of English spoken in Northern Ireland shows heavy influence by that of Scotland, thereby giving it a distinct accent compared to other forms of Hiberno-English, along with the use of such Scots words as wee for 'little' and aye for 'yes'. Some jocularly call this version of Hiberno-English phonetically by the name Norn Iron. There are supposedly some minute differences in pronunciation between Protestants and Catholics, the best known of which is the name of the letter h, which Protestants tend to pronounce as "aitch", as in British English, and Catholics tend to pronounce as "haitch", as in Hiberno-English. However, geography is a much more important determinant of dialect than ethnic background. English is by far the most widely spoken language in Northern Ireland.
For much of their existence electricity networks in the Republic of Ireland and Northern Ireland were entirely separate. Both networks were designed and constructed independently, but are now connected with three interlinks and also connected by Northern Ireland Electricity (NIE) though Great Britain to mainland Europe. The Electricity Supply Board (ESB) in the Republic drove a rural electrification programme in the 1940s until the 1970s.
In recent decades the Catholic population has increased in percentage terms within Northern Ireland, while the Presbyterian and Church of Ireland population percentages have decreased. However the decreasing size of Catholic families and the increasing use of birth control among the Catholic community and led to a slowing down in the growth of the Catholic population. Statisticians predict both communities will achieve close to parity in size, with Protestants dominant primarily to the east of Northern Ireland and Catholics dominant to the west and south. However as of 2005 most statisticians predict that Protestants will continue to slightly outnumber Catholics in Northern Ireland as a whole. As not all Catholics are nationalists, they predict a continuing majority in favour of the union with the United Kingdom. However this is disputed by a minority of statisticians.
The parliament of the Republic of Ireland is the Oireachtas. The Oireachtas consists of the President and two houses: Dáil Éireann and Seanad Éireann (also known as the Senate). The Dáil is by far the dominant tier of the legislature. The President may not veto laws in most circumstances and the Senate may only delay legislation.
For a comparatively small country, Ireland has made a disproportionate contribution to world literature in all its branches. The works that are best known outside the country are in English, but Irish Gaelic also has the most significant body of written literature, both ancient and recent, of any Celtic language, in addition to a strong oral tradition of legends and poetry. Poetry in Irish represents the oldest vernacular poetry in Europe, with the earliest examples dating from the 6th century. In more recent times, Ireland has produced four winners of the Nobel Prize for Literature; George Bernard Shaw, William Butler Yeats, Samuel Beckett and Seamus Heaney
A majority of the present-day population are unionist and wish to remain part of the United Kingdom, but a significant minority, known as nationalists, want to see a united Ireland. These two views are linked to deeper cultural divisions. Unionists are predominantly Protestant and often descendants of Scottish and English (mainly Scottish) settlement in previous centuries, while nationalists are predominantly Catholic and usually descend from the Irish population predating such settlement. The conflict between these two sets of identities, including alleged discrimination against nationalists under the Stormont government (1920–72) giving rise to the nationalist "Civil Rights Movement" in the 1960s, and eventually to a long-running conflict known as The Troubles.
There are many references to food and drink in early Irish literature. Honey seems to have been widely eaten and used in the making of mead. The old stories also contain many references to banquets, although these may well be greatly exaggerated and provide little insight to every diet. There are also many references to fulacht fiadh. These were sites for cooking deer, and consisted of holes in the ground which were filled with water. The meat was placed in the water and cooked by the introduction of hot stones. Many fulacht fiadh sites have been identified across the island of Ireland, and some of them appear to have been in use up to the 17th century.
In 1800 the Irish Parliament passed the Act of Union which, in 1801, merged the Kingdom of Ireland and the Kingdom of Great Britain to create the United Kingdom of Great Britain and Ireland. The whole island of Ireland would remain within the United Kingdom, rule directly by the UK Parliament in London. The nineteenth century saw considerable economic difficulties for Ireland, including the Great Famine of the 1840s in which about 750,000 people died and another million were forced to emigrate.
The culture of the people living on the island of Ireland is far from monolithic. Many notable cultural divides exist between the rural people and city dwellers, between the Catholic and Protestant people of Northern Ireland, between the Irish-speaking people within and without the Gaeltacht regions and the English-speaking majority population, between the settled people and the Travellers, and, increasingly, between new immigrants and the native population.
