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.
A ring of coastal mountains surrounds low central plains. The highest peak is Carrauntuohill (Irish: Corrán Tuathail), which is 1041 m (3414 feet). The island is bisected by the River Shannon, at 113 km (70 mi) the longest river in Ireland or Britain. The island's lush vegetation, a product of its mild climate and frequent but soft rainfall, earns it the sobriquet "Emerald Isle".
With its improved international reputation, Northern Ireland has recently witnessed rising numbers of tourists who come to appreciate the area's unique heritage. Attractions include cultural festivals, musical and artistic traditions, countryside and geographical sites of interest, pubs, welcoming hospitality and sports (especially golf and fishing).
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 area now known as Northern Ireland has had a diverse history. From serving as the bedrock of Irish resistance in the era of the plantations of Queen Elizabeth and James I in other parts of Ireland, it became itself the subject of major planting of Scottish and English settlers after the Flight of the Earls in 1607 (when the native aristocracy left en masse).
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.
Ulster Scots comprises varieties of the Scots language spoken in Northern Ireland. Many claim it has become a separate language, descended from Scots in Scotland, whereas others question whether Scots is a separate language from English at all, or simply a collection of local dialects of Scottish and Northern Ireland Hiberno-English.
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.
Northern Ireland was covered by an ice sheet for most of the last ice age and on numerous previous occasions, the legacy of which can be seen in the extensive coverage of drumlins in Counties Fermanagh, Armagh, Antrim and particularly Down. The centrepiece of Northern Ireland's geography is Lough Neagh, at 392 km² the largest freshwater lake in the British Isles. A second extensive lake system is centred on Lower and Upper Lough Erne in Fermanagh.
The head of state is the President of Ireland. In keeping with the state's parliamentary system of government the President exercises largely a ceremonial role but does possess certain reserve powers. The presidency is open to all citizens who are at least 35. They are directly elected by secret ballot under the Alternative Vote. A candidate may also be chosen by a consensus among the political parties, in which case it is unnecessary to proceed to a ballot. The President is elected to a seven year term; no candidate may serve more than two terms. In carrying out certain of her constitutional functions, the President is aided by the Council of State.
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.
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.
The potato would appear to have been introduced into Ireland in the second half of the 17th century, initially as a garden crop. It eventually came to be the main food field crop of the tenant and labouring classes. As a food source, the potato is extremely efficient in terms of energy yielded per unit area of land. The potato is also a good source of many vitamins and minerals, particularly vitamin C (especially when fresh).
