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).
The Anglo-Irish Treaty was narrowly ratified by the Dáil in December 1921 but was rejected a large minority, resulting in the Irish Civil War which lasted until 1923. In 1922, in the middle of this war, the Irish Free State came into being. For its first years the new state was governed by the victors of the Civil War. However in the 1930s Fianna Fáil, the party of the opponents of the treaty, were elected into government. The party introduced a new constitution in 1937 which renamed the state to simply "Ireland".
As archaeological evidence from sites such as the Céide Fields in County Mayo and Lough Gur in County Limerick demonstrates, farming in Ireland is an activity that goes back to the very beginnings of human settlement. In historic times, texts such as the Táin Bó Cúailinge show a society in which cattle represented a primary source of wealth and status. Little of this had changed by the time of the Norman conquest of Ireland in the 12th century. Giraldus Cambrensis portrays a Gaelic society in which cattle farming and transhumance is the norm. Three hundred years later, the society depicted in Edmund Spenser's A View of the Present State of Ireland had changed remarkably little. Even today, when a quarter of the population of the Republic lives in Dublin, the cattle population is of the order of 6.7 million. The total population of humans on the island, north and south, only just approaches this figure.
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.
There have been recent efforts in Ireland to use renewable energy such as wind energy with large wind farms being constructed in coastal counties such as Mayo and County Antrim. Recently what will be the world's largest offshore wind farm is being developed at Arklow Bank off the coast of Wicklow. It is estimated to generate 10% of Irelands energy needs when it is complete. These constructions have in some cases been delayed by opposition from locals, most recently on Achill Island, some of whom consider the wind turbines to be unsightly. Another issue in the Republic of Ireland is the failure of the aging network to cope with the varying availability of power from such installations. Turlough Hill is the only energy storage mechanism in Ireland.
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.
The Irish tradition of folk music and dance is also widely known. In the middle years of the 20th century, as Irish society was attempting to modernise, traditional music fell out of favour to some extent, especially in urban areas. Young people at this time tended to look to Britain and, particularly, the United States as models of progress and jazz and rock and roll became extremely popular. During the 1960s, and inspired by the American folk music movement, there was a revival of interest in the Irish tradition. This revival was inspired by groups like The Dubliners, the Clancy Brothers and Sweeney's Men and individuals like Sean Ó Riada.
Ireland (Éire in Irish) is the third-largest island in Europe. It lies on the west side of the Irish Sea, close to the island of Great Britain. It is composed of the Republic of Ireland which covers five sixths of the island (south, east, west and north-west) and Northern Ireland, a part of the United Kingdom, which covers the northeastern sixth of the island. The population of the island is approximately 5.7 million people, most of whom live on the east coast.
Pub culture, as it is termed, pervades Irish society, across all cultural divides. The term refers to the Irish habit of frequenting public houses (pubs) or bars. Traditional pub culture is concerned with more than just drinking, even though Ireland has a recognised problem with over-consumption of alcohol, with the highest drink consumption in Europe. Per capita alcohol consumption increased by 41% in the period 1989 to 1999. Typically pubs are important meeting places, where people can gather today in the modern Ireland and meet their neighbours and friends in a relaxed atmosphere. Pubs vary widely according to the clientele they serve, and the area they are in. Best known, and loved amongst tourists is the traditional pub, with its tradional Irish music (or "trad music"), tavern-like warmness, and memorabilia filling it.
The Republic of Ireland is a sovereign, independent state. It is a representative democracy under a parliamentary system of government, with a president, prime minister and parliament. The capital city is Dublin. While there are a number of important political parties in the state, the two largest are Fianna Fáil and Fine Gael. The state is a member of the European Union.
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.
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".
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.
