Political parties in Northern Ireland can be divided into three distinct categories: unionist parties, such as the Democratic Unionist Party, the Ulster Unionist Party, and other smaller parties such as the Progressive Unionist Party and the United Kingdom Unionist Party; nationalist parties, Sinn Féin and the Social Democratic and Labour Party (SDLP); and cross-community parties such as the Alliance Party and the Northern Ireland Women's Coalition.
Much of the Irish calendar still today reflects the old pagan customs, with later Christian traditions also having significant influence. As in other countries, the date for observing Christmas was deliberately chosen to coincide with the winter solstice. Christmas in Ireland has several local traditions, some in no way connected with Christianity. On 6 January, which is known as "The Little Christmas" (An Nollaig Bhéag) or "The Women's Christmas" (Nollaig na mBan), there is a custom of "Wren boys" who call door to door, in times past, with a dead wren.
The three most important international airports in the Republic are Dublin Airport, Cork Airport and Shannon Airport. All provide extensive services to the UK, Europe and North America. The Irish national airline Aer Lingus and low-cost operator Ryanair are based at Dublin. Shannon is an important stopover on trans-Atlantic route for refuelling operations. There are several smaller regional airports in the Republic (Galway Airport, Kerry Airport, Knock Airport, Sligo Airport, Waterford Airport) that mostly limit their services to Ireland and the United Kingdom.
The whole of Northern Ireland has a temperate maritime climate, rather wetter in the west than the east although cloud cover is persistent across the region. The weather is unpredictable at all times of the year, and although the seasons are distinct they are considerably less pronounced than in interior Europe or the eastern seaboard on North America. Average daytime maximums in Belfast are 6.5°C in January and 17.5°C in July. The damp climate and extensive deforestation in the 16th and 17th Centuries results in much of the region being covered in rich green grassland.
Ireland is well supplied with museums and art galleries and offers, especially during the summer months, a wide range of cultural events. These range from arts festivals to farming events. The most popular of these are the annual Dublin Saint Patrick's Day Festival which attracts on average 500,000 people and the National Ploughing Championships with an attendance in the region of 400,000. There are also a number of Summer Schools on topics from traditional music to literature and the arts.
Most Northern Irish Catholics support unification, although opinion polls have shown a minority who support remaining part of the UK, usually while continuing to support nationalist political parties. This proportion has slowly but steadily declined over the course of the Troubles. The proportion of Protestants who wish to join the Republic is smaller. There are also considerable numbers of people who give ambiguous answers to questions about the future constitutional status of Northern Ireland.
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.
Since its foundation it has been the stated long-term policy of governments of the state now called the Republic of Ireland to bring an end to the conflict in Northern Ireland and to bring about a united Ireland. Northern Ireland has also, in the past, often been a source of conflict between the Irish Government and the government of the United Kingdom. In order to find a solution to the Troubles the Irish Government became a partner in the Good Friday (Belfast) Agreement in 1998.
The all-island Kingdom of Ireland (1541-1801) was incorporated into the United Kingdom in 1801 under the terms of the Act of Union, under which the kingdoms of Ireland and Great Britain merged under a central parliament, government and monarchy based in London. In the early 20th century Unionists, led by Sir Edward Carson, opposed the introduction of Home Rule in Ireland. Unionists were in a minority on the island of Ireland as a whole, but formed a majority in the northern province of Ulster. Therefore, after the First World War, Ireland was partitioned in 1921 under the terms of the Government of Ireland Act 1920 between six of the nine Ulster counties in the northeast (forming Northern Ieland) and the remaining twenty-six counties of the south and west (forming Southern Ireland and became the Irish Free State in 1922). When the latter achieved dominion status, the six Northern Ireland counties — under the procedures laid out in the Anglo-Irish Treaty, 1921 — opted out, and so remain as part of the United Kingdom.
The island is often referred to as being part of the British Isles. However, some people, especially in Ireland, take exception to this name, which seems to suggest that both islands belong to Britain. For this reason, "Britain and Ireland" is commonly used as a more neutral alternative. Another suggestion, although much less used, is the Islands of the North Atlantic (IONA).
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 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.
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.
