Ireland Map

• Food and cuisine in Ireland takes its influence from the crops grown and animals farmed in the island's temperate climate and from the social and political circumstances of Irish history. For example, whilst from the Middle Ages until the arrival of the potato in the 16th century the dominant feature of the Irish economy was the herding of cattle, the number of cattle a person owned was equated to their social standing. Thus herders would avoid slaughtering a milk-producing cow.

• For this reason, pork and white meat were more common than beef and a thick fatty strips of salted bacon (or rashers) and the eating of salted butter (i.e. a dairy product rather than beef itself) have been a central feature of the diet in Ireland since the Middle Ages. The practice of bleeding cattle and mixing the blood with milk and butter (not unlike the practice of the Maasai) was common and black pudding, made from blood, grain (usually barley) and seasoning, remains a breakfast staple in Ireland. All of these influences can be seen today in the phenomenon of the "breakfast roll".

• The introduction of the potato in the second half of the 16th century heavily influenced cuisine thereafter. Great poverty encouraged a subsistence approach to food and by the mid-19th century the vast majority of the population sufficed with a diet of potatoes and milk. A typical family, consisting a man, a woman and four children, would eat 18 stone (110 kg) of potatoes a week. Consequently, dishes that are considered as national dishes represent a fundamental unsophistication to cooking, such as the Irish stew, bacon and cabbage, boxty, a type of potato pancake, or colcannon, a dish of mashed potatoes and kale or cabbage.

• Since the last quarter of the 20th century, with a re-emergence of wealth in Ireland, a "New Irish Cuisine" based on traditional ingredients incorporating international influences has emerged. This cuisine is based on fresh vegetables, fish (especially salmon, trout, oysters, mussels and other shellfish), as well as traditional soda breads and the wide range of hand-made cheeses that are now being produced across the country. The potato remains however a fundamental feature of this cuisine and the Irish remain the highest per capita consumers of potatoes in Europe. An example of this new cuisine is "Dublin Lawyer": lobster cooked in whiskey and cream. Traditional regional foods can be found throughout the country, for example coddle in Dublin or drisheen in Cork, both a type of sausage, or blaa, a doughy white bread particular to Waterford.

• Ireland once dominated the world's market for whiskey, producing 90% of the world's whiskey at the start of the 20th century. However, as a consequence of bootleggers during the prohibition in the United States (who sold poor-quality whiskey bearing Irish-sounding names thus eroding the pre-prohibition popularity for Irish brands) and tariffs on Irish whiskey across British Empire during the Anglo-Irish Trade War of the 1930s, sales of Irish whiskey worldwide fell to a mere 2% by the mid-20th century. In 1953, an Irish government survey, found that 50 per cent of whiskey drinkers in the United States had never heard of Irish whiskey.

• Irish whiskey, however, remained popular domestically and in recent decades has grown in popularity again internationally. Typically, Irish whiskey is not as smoky as a Scotch whisky, but not as sweet as American or Canadian whiskies. Whiskey forms the basis of traditional cream liqueurs, such as Baileys, and the "Irish coffee" (a cocktail of coffee and whiskey reputedly invented at Foynes flying-boat station) is probably the best-known Irish cocktail.

• Stout, a kind of porter beer, particularly Guinness, is typically associated with Ireland, although historically it was more closely associated with London. Porter remains very popular, although it has lost sales since the mid-20th century to lager. Cider, particularly Magners (marketed in the Republic of Ireland as Bulmers), is also a popular drink. Red lemonade, a soft-drink, is consumed on its own and as a mixer, particularly with whiskey.

• Northern Ireland was created as a division of the United Kingdom by the Government of Ireland Act 1920 and until 1972 it was a self-governing jurisdiction within the United Kingdom with its own parliament and prime minister. Northern Ireland, as part of the United Kingdom, was not neutral during the Second World War and Belfast suffered four bombing raids in 1941. Conscription was not extended to Northern Ireland and roughly an equal number volunteered from Northern Ireland as volunteered from the south. One, James Joseph Magennis, received the Victoria Cross for valour.

• Although Northern Ireland was largely spared the strife of the civil war, in decades that followed partition there were sporadic episodes of inter-communal violence. Nationalists, mainly Roman Catholic, wanted to unite Ireland as an independent republic, whereas unionists, mainly Protestant, wanted Northern Ireland to remain in the United Kingdom. The Protestant and Catholic communities in Northern Ireland voted largely along sectarian lines, meaning that the Government of Northern Ireland (elected by "first past the post" from 1929) was controlled by the Ulster Unionist Party. Over time the minority Catholic community felt increasingly alienated with further disaffection fueled by practices such as gerrymandering and discrimination in housing and employment.

• In the late 1960s nationalist grievances were aired publicly in mass civil rights protests, which were often confronted by loyalist counter-protests. The government's reaction to confrontations was seen to be one-sided and heavy-handed in favour of unionists. Law and order broke down as unrest and inter-communal violence increased. The Northern Ireland government requested the British Army to aid the police, who were exhausted after several nights of serious rioting. In 1969 the paramilitary Provisional IRA, which favoured the creation of a united Ireland, emerged from a split in the Irish Republican Army and began a campaign against what it called the "British occupation of the six counties".

• Other groups, on both the unionist side and the nationalist side, participated in violence and a period known as the Troubles began. Over 3,600 deaths resulted over the subsequent three decades of conflict. Owing to the civil unrest during the Troubles, the British government suspended home rule in 1972 and imposed "direct rule" from the Parliament of the United Kingdom. There were several ultimately unsuccessful attempts to end the Troubles politically, such as the Sunningdale Agreement of 1973. In 1998, following a ceasefire by the Provisional IRA and multi-party talks, the Belfast Agreement was concluded as a treaty between the United Kingdom and the Republic of Ireland, annexing the text agreed in the multi-party talks; the substance of the Agreement (often referred to as the Good Friday Agreement) was later endorsed by referendums in both parts of the island of Ireland. The Agreement restored self-government to Northern Ireland on the basis of power-sharing in a regional Executive drawn from the major parties in a new Northern Ireland Assembly, with entrenched protections for the two main communities. The Executive ministries were jointly headed by a First Minister and deputy First Minister drawn from the unionist and nationalist parties. Violence decreased greatly after the signing of the accord and in 2005 the Provisional IRA announced the end of its armed campaign and an independent commission supervised its disarmament and that of other nationalist and unionist paramilitary organisations. The Assembly and power-sharing Executive were suspended several times but were restored again in 2007. In that year the British government officially ended its military support of the police in Northern Ireland (Operation Banner) and began withdrawing troops.

• Ireland was largely passed over by the industrial revolution. One reason given why Ireland did not experience an industrial revolution is because of the scarcity of coal and iron, resources that facilitate an industrial revolution. However, there were other countries that lacked these resources but nonetheless industrialised, so there may be other reasons why Ireland did not industrialise. Nineteenth century explanations for why Ireland did not industrialise did not blame the absence of natural resources but that "The fault is not in the country, but in ourselves; the absence of successful enterprise is owing to the fact, that we do not know how to succeed ... we want special industrial knowledge." Some historians today point to the sudden union with the structurally superior economy of England. They point out that iron and coal prices in Ireland were as cheap as they were in parts of England outside of the mining centres – and a little cheaper in some parts – and that, on the eve of union with Great Britain, Ireland was industrialising (particularly the linen industry). It may be that, by merging the two economies suddenly, Ireland did not industrialise, but "instead became a supplier of food – and capital – to the 'mainland'."

• Mass emigration followed in the wake of the Great Famine in the mid-19th century and continued until the 1980s. However, the Irish economic experience reversed dramatically during the course of the 1990s, which saw the beginning of unprecedented economic growth in the Republic of Ireland, in a phenomenon known as the "Celtic Tiger", and peace being restored in Northern Ireland. In 2005 the Republic of Ireland was ranked the best place to live in the world according to a "quality of life" assessment by The Economist magazine. The Republic of Ireland joined the euro in 1999, while Northern Ireland remained with the pound sterling. Both the Republic of Ireland and Northern Ireland entered recession in 2008 and, in 2009, the unemployment rate for the Republic of Ireland was 12.5% due to the 2008–2010 Irish financial crisis.

• The Irish philosopher and theologian Johannes Scotus Eriugena was considered one of the leading intellectuals of his early Middle Ages. Sir Ernest Henry Shackleton, an Anglo-Irish explorer, was one of the principal figures of Antarctic exploration. He, along with his expedition, made the first ascent of Mount Erebus and the discovery of the approximate location of the South Magnetic Pole. Robert Boyle was an 17th century natural philosopher, chemist, physicist, inventor and early gentleman scientist. He is largely regarded one of the founders of modern chemistry and is best known for the formulation of Boyle's law. 19th century physicist, John Tyndall, discovered the Tyndall effect, which explains why the sky is blue. Father Nicholas Joseph Callan, Professor of Natural Philosophy in Maynooth College, is best known for his invention of the induction coil, transformer and he discovered an early method of galvanisation in the 19th century.

• Other notable Irish physicists include Ernest Walton, winner of the 1951 Nobel Prize in Physics. With Sir John Douglas Cockcroft, he was the first to split the nucleus of the atom by artificial means and made contributions to the development of a new theory of wave equation. William Thomson, or Lord Kelvin, is the person whom the absolute temperature unit, the Kelvin, is named after. Sir Joseph Larmor, a physicist and mathematician, made innovations in the understanding of electricity, dynamics, thermodynamics and the electron theory of matter. His most influential work was Aether and Matter, a book on theoretical physics published in 1900.

• George Johnstone Stoney introduced the term electron in 1891. John Stewart Bell was the originator of Bell's Theorem and a paper concerning the discovery of the Bell-Jackiw-Adler anomaly and was nominated for a Nobel prize. Notable mathematicians include Sir William Rowan Hamilton, famous for the invention of quaternions. Francis Ysidro Edgeworth was influential in the development of neo-classical economics, including the Edgeworth box. John B. Cosgrave was a specialist in number theory and discovered a 2000-digit prime number in 1999 and a record composite Fermat number in 2003. John Lighton Synge made progress in different fields of science, including mechanics and geometrical methods in general relativity. He had mathematician John Nash as one of his students.

• Ireland has eight universities and numerous Institutes of Technologies as well as The Dublin Institute for Advanced Studies, which was established in 1940 with physicist Erwin Schrödinger as director.

• Ireland's culture comprises elements of the culture of ancient immigration and influences (such as Gaelic culture) and more recent Anglicisation and Americanisation as well as participation in a broader European culture. In broad terms, Ireland is regarded as one of the Celtic nations of Europe, which also includes Scotland, Wales, Cornwall, Isle of Mann and Brittany. This combination of cultural influences is visible in the intricate designs termed Irish interlace or Celtic knotwork. These can be seen in the ornamentation of medieval religious and secular works. The style is still is popular today in jewellery and graphic art, as is the distinctive style of traditional Irish music and dance, and has become indicative of modern "Celtic" culture in general.

• Religion has played a significant role in the cultural life of the island since ancient times (and since the 17th century plantations, has been the focus of political identity and divisions on the island). Ireland's pre-Christian heritage fused with the Celtic Church following the missions of Saint Patrick in the 5th century. The Hiberno-Scottish missions, begun by the Irish monk Saint Columba, spread the Irish vision of Christianity to pagan England and the Frankish Empire. These missions brought written language to an illiterate population of Europe during the Dark Ages that followed the fall of Rome, earning Ireland the sobriquet, "the island of saints and scholars". In more recent years, the Irish pubs have become outposts of Irish culture worldwide.

• The Republic of Ireland's national theatre is the Abbey Theatre founded in 1904 and the national Irish-language theatre is An Taibhdhearc, established in 1928 in Galway. Playwrights such as Seán O'Casey, Brian Friel, Sebastian Barry, Conor McPherson and Billy Roche are internationally renowned.
