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 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.
The Constitution of Ireland guarantees the rights of the family and the institution of marriage. However, the reality is that social and economic change in recent years has brought about significant changes in family life in the Republic. According to figures published in September, 2004, 31% of all births in the Republic of Ireland occur outside marriage. This compares with 5% in 1980. The average of mothers having their first child was 30 and the fertility is an average of 1.98 children.
The late nineteenth and early twentieth centuries saw a vigorous but unsuccessful campaign for Irish home rule, followed by the eclipse of moderate nationalism by militant separatism. In 1922, following the Anglo-Irish War, the twenty-six counties of Ireland seceded from the United Kingdom as the Irish Free State. The remaining six, in the north-east, remained within the Union as Northern Ireland. Secession for southern Ireland led directly to the Civil War, as militant nationalists split into two factions and turned against one another.
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 significant recent change to pub culture in Ireland has been the introduction of a smoking ban, in all workplaces, which includes pubs and restaurants. The ban was introduced on 29 March 2004. A majority of the population support the ban, including a significant percentage of smokers. Nevertheless, the atmosphere in pubs has changed greatly as a result, regardless of whether it has boosted or lowered sales, or whether it is a "good thing" or a "bad thing".
The state operates under the Constitution of Ireland, also known as Bunreacht na hÉireann, adopted in 1937. The constitution falls broadly within the liberal democratic tradition. It defines the organs of government and guarantees certain fundamental rights. The constitution may only be amended by referendum. Important constitutional referenda have concerned issues such as abortion, the status of the Catholic Church, divorce and the European Union.
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.
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.
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".
Many Irish urban centres developed as garrison towns during the years of British rule and this fact contributed towards their particular character. Another significant factor was the fact thar the Industrial Revolution had a limited impact in Ireland. Belfast had its shipbuilding and a number of towns in Ulster had mechanised linen industries, but the majority of towns developed primarily as commercial and administrative centres. By the end of the 20th century, over 50% of the population lived in these urban areas.
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.
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".
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.
