Origins and antecedents


Prehistoric and legendary ancestors

During the past 33,000 years, Ireland has witnessed different peoples arrive on its shores. Pytheas made a voyage of exploration to northwestern Europe in about 325 BC, but his account of it, known widely in Antiquity, has not survived and is now known only through the writings of others. On this voyage, he circumnavigated and visited a considerable part of modern-day

. In the cases of the Conmaicne, Delbhna, and perhaps Érainn, it can be demonstrated that the tribe took their name from their chief deity, or in the case of the Ciannachta, Eóganachta, and possibly the Soghain, a deified ancestor. This practice is paralleled by the Anglo-Saxon dynasties. One legend states that the Irish were descended from the Milesians, who supposedly conquered Ireland around 1000 BC or later.

. A DNA study found they originally descended from the general Irish population, however, they are now very distinct from it. The emergence of Travellers as a distinct group occurred long before the Great Famine, a genetic analysis shows. The research suggests that Traveller origins may in fact date as far back as 420 years to 1597. The Plantation of Ulster began around that time, with native Irish displaced from the land, perhaps to form a nomadic population.


History


Early expansion and the coming of Christianity

One Roman historian records that the Irish people were divided into "sixteen different nations" or tribes.MacManus, p 86 Traditional histories assert that the Romans never attempted to conquer Ireland, although it may have been considered. The Irish were not, however, cut off from Europe; they frequently raided the Roman territories, and also maintained trade links. Among the most famous people of ancient Irish history are the

He states that "the Irish migration hypothesis seems to be a classic case of long-held historical beliefs influencing not only the interpretation of documentary sources themselves but the subsequent invasion paradigm being accepted uncritically in the related disciplines of archaeology and linguistics."Campbell, Ewan.

and the Eastern Orthodox Christian theology, Greek theological tradition, previously almost unknown in the Latin West. The influx of Viking raiders and traders in the 9th and 10th centuries resulted in the founding of many of Ireland's most important towns, including Cork (city), Cork, Dublin, Limerick, and Waterford (earlier Gaelic settlements on these sites did not approach the urban nature of the subsequent Norse trading ports). The Vikings left little impact on Ireland other than towns and certain words added to the Irish language, but many Irish taken as slaves inter-married with the Scandinavians, hence forming a close link with the Icelandic people. In the Icelandic ''Laxdœla saga'', for example, "even slaves are highborn, descended from the kings of Ireland." The first name of Njáll Þorgeirsson, the chief protagonist of ''Njáls saga'', is a variation of the Irish name Neil.

Surnames

The Irish were among the first people in Europe to use surnames as we know them today. It is very common for people of Gaels, Gaelic origin to have the English versions of their surnames beginning with 'Ó' or 'Mac' (Over time however many have been shortened to 'O' or Mc). 'O' comes from the Irish Ó which in turn came from Ua, which means "grandson (son of a child), grandson", or "Kinship, descendant" of a named person. Mac is the Irish for son. Names that begin with "O'" include Ó Bánion (O'Banion), Ó Briain (O'Brien (surname), O'Brien), Ó Ceallaigh (Kelly (surname), O'Kelly), Ó Conchobhair (O'Conor, O'Connor, O'Conor), Ó Chonaill (O'Connell (name), O'Connell), O'Coiligh (Cox (surname), Cox), Ó Cuilinn (Cullen (surname), Cullen), Ó Domhnaill (O'Donnell), Ó Drisceoil (O'Driscoll), Ó hAnnracháin, (Hanrahan), Ó Máille (O'Malley (surname), O'Malley), Ó Mathghamhna (O'Mahony), Ó Néill (O'Neill (surname), O'Neill), Ó Sé (O'Shea), Ó Súilleabháin (O'Sullivan), Ó Caiside/Ó Casaide (Cassidy (surname), Cassidy), (Brady (surname), Brady) Ó Brádaigh/Mac Bradaigh and Ó Tuathail (O'Toole (surname), O'Toole) Names that begin with Mac or Mc include Mac Cárthaigh (McCarthy (surname), MacCarthy), Mac Diarmada (McDermott, MacDermott), Mac Domhnaill (McDonnell (surname), MacDonnell), and Mac Mathghamhna (McMahon, MacMahon) Mag Uidhir (Maguire)), (McDonagh), (MacNamara), (McInerney), (MacGrath), (McEnery), (McGee (name), McGee), (Magennis), (McCann (surname), McCann), (McLaughlin (surname), McLaughlin) and (McNally (surname), McNally) Mac is commonly anglicised Mc. However, "Mac" and "Mc" are not mutually exclusive, so, for example, both "MacCarthy" and "McCarthy" are used. Both "Mac" and "Ó'" prefixes are both Irish in origin, Anglicized Prefix Mc is far more common in Ireland than Scotland with 2/3 of all Mc Surnames being Irish in origin However, "Mac" is more common in Scotland and Ulster than in the rest of Ireland; furthermore, "Ó" surnames are less common in Scotland having been brought to Scotland from Ireland. The proper surname for a woman in Irish uses the feminine prefix nic (meaning daughter) in place of mac. Thus a boy may be called Mac Domhnaill whereas his sister would be called Nic Dhomhnaill or Ní Dhomhnaill – the insertion of 'h' follows the female prefix in the case of most consonants (bar H, L, N, R, & T). A son has the same surname as his father. A female's surname replaces Ó with Ní (reduced from Iníon Uí – "daughter of the grandson of") and Mac with Nic (reduced from Iníon Mhic – "daughter of the son of"); in both cases the following name undergoes lenition. However, if the second part of the surname begins with the letter C or G, it is not lenited after Nic. Thus the daughter of a man named Ó Maolagáin has the surname ''Ní Mhaolagáin'' and the daughter of a man named Mac Gearailt has the surname ''Nic Gearailt''. When anglicised, the name can remain O' or Mac, regardless of gender. There are a number of Irish surnames derived from Norse personal names, including Clan Sweeney, Mac Suibhne (Sweeney) from Swein and McAuliffe from "Olaf". The name Cotter family, Cotter, local to County Cork, derives from the Norse personal name Ottir. The name Reynolds (surname), Reynolds is an Anglicization of the Irish Mac Raghnaill, itself originating from the Norse names Randal or Reginald. Though these names were of Viking derivation some of the families who bear them appear to have had Gaelic origins. "Fitz" is an old Norman French variant of the Old French word ''fils'' (variant spellings filz, fiuz, fiz, etc.), used by the Normans, meaning ''son''. The Normans themselves were descendants of
Vikings Vikings ; non, víkingr is the modern name given to seafaring people originally from Scandinavia (present-day Denmark, Norway and Sweden), who from the late 8th to the late 11th centuries raided, pirated, traded and ...
, who had settled in Normandy and thoroughly adopted the French language and culture. With the exception of the Gaelic-Irish Fitzpatrick (name), Fitzpatrick (Mac Giolla Phádraig) surname, all names that begin with Fitz – including FitzGerald (Mac Gearailt), Fitzsimons (Mac Síomóin/Mac an Ridire) and FitzHenry (Mac Anraí) – are descended from the initial Norman settlers. A small number of Irish families of Goidelic origin came to use a Norman form of their original surname—so that Mac Giolla Phádraig became Fitzpatrick—while some assimilated so well that the Irish name was dropped in favour of a new, Hiberno-Norman form. Another common Irish surname of Hiberno-Norman, Norman Irish origin is the 'de' habitational prefix, meaning 'of' and originally signifying prestige and land ownership. Examples include de Búrca (Burke), de Brún, de Barra (Barry), de Stac (Stack), de Tiúit, de Faoite (White), de Londras (Landers), de Paor (Power). The Irish surname "Walsh" (in Irish ''Breathnach'') was routinely given to settlers of Welsh people, Welsh origin, who had come during and after the Norman invasion. The Joyce and Griffin/Griffith (Gruffydd) families are also of Welsh origin. The Mac Lochlainn, Ó Maol Seachlainn, Ó Maol Seachnaill, Ó Conchobhair, Mac Loughlin and Mac Diarmada families, all distinct, are now all subsumed together as MacLoughlin. The full surname usually indicated which family was in question, something that has been diminished with the loss of prefixes such as Ó and Mac. Different branches of a family with the same surname sometimes used distinguishing epithets, which sometimes became surnames in their own right. Hence the chief of the clan Ó Cearnaigh (Kearney) was referred to as An Sionnach (Fox), which his descendants use to this day. Similar surnames are often found in Scotland for many reasons, such as the use of a common language and mass Irish migration to Scotland in the late 19th and early to mid-20th centuries.

, the explorer Christopher Columbus visited Ireland to gather information about the lands to the west,MacManus, p 343–344 a number of Irish names are recorded on Columbus' crew roster preserved in the archives of Madrid and it was an Irishman named Patrick Maguire who was the first to set foot in the Americas in 1492; however, according to Samuel Eliot Morison, Morison and Miss Gould, who made a detailed study of the crew list of 1492, no Irish or English sailors were involved in the voyage. An English report of 1515 states that the Irish people were divided into over sixty Gaelic lordships and thirty Anglo-Irish lordships.Nicholls The English term for these lordships was "nation" or "country". The Irish term "''oireacht''" referred to both the territory and the people ruled by the lord. Literally, it meant an "assembly", where the Brehons would hold their courts upon hills to arbitrate the matters of the lordship. Indeed, the Tudor lawyer John Davies (poet, born 1569), John Davies described the Irish people with respect to their laws: Another English commentator records that the assemblies were attended by "all the scum of the country"—the labouring population as well as the landowners. While the distinction between "free" and "unfree" elements of the Irish people was unreal in legal terms, it was a social and economic reality. Social mobility was usually downwards, due to social and economic pressures. The ruling clan's "expansion from the top downwards" was constantly displacing commoners and forcing them into the margins of society. As a clan-based society, genealogy was all important. Ireland 'was justly styled a "Nation of Annalists"'. The various branches of Irish learning—including law, poetry, history and genealogy, and medicine—were associated with hereditary learned families. The poetic families included the Ó Dálaigh, Uí Dhálaigh (Daly) and the MacGrath (disambiguation), MacGrath. Irish physicians, such as the O'Briens in Munster or the MacCailim Mor in the Western Isles, were renowned in the courts of England, Spain, Portugal and the Low Countries.MacManus, p 348 Learning was not exclusive to the hereditary learned families, however; one such example is Cathal Óg Mac Maghnusa, Cathal Mac Manus, the 15th century diocesan priest who wrote the ''Annals of Ulster''. Other learned families included the Mac Aodhagáin, Mic Aodhagáin and Clan MacFhirbhisigh, Clann Fhir Bhisigh. It was this latter family which produced Dubhaltach Mac Fhirbhisigh, the 17th century genealogist and compiler of the ''Leabhar na nGenealach''. (see also Irish medical families).


Plantations

The 16th century Age of exploration brought an interest among the English to colonize Ireland with the reign of the Tudors. King Henry IV established surrender and regrants to the Irish, but it wasn't until the catholic queen Mary I of England who started the first plantations in Ireland in 1550, this would become the model for English colonization moving forward in Ireland and would later form the British imperial model The 1550 plantation counties were known as Philipstown (now Daingean) and Maryborough (now Portlaoise) named by the English planters at the time. A famous group of explorers the West Country Men were active in Ireland at around this time. The Enterprise of Ulster which pitted Shane O'Neill (Irish chieftain) against Queen Elizabeth I was a total failure This was followed by the somewhat successful first British-English colony the Plantations of Ireland, Munster planations which had a population of 4,000 in 1580 and in the 1620s may have grown to 16,000 After the defeat of the Irish in Ulster in the Nine Years' War (Ireland); which was not exclusively confined to ulster. The English would try again to colonize Ireland fearing another rebellion in Ulster, using previous colonial Irish endeavours as their influence. King James would succeed Queen Elizabeth the I, because King James I was previously King James VI of Scotland, he would plant both English and Scottish in the plantations of Ulster drawing upon the Munster Plantations, this proved to be the most successful they were settled in what's mostly Now Northern Ireland. The Plantations of Ireland introduced Tudor English settlers to Ireland, while The Plantation of Ulster in the 17th century introduced a great number of Scottish and to a lesser extent English as well as French Huguenots as colonists. All previous endeavours were solely an English venture. The Lord Protector Oliver Cromwell (1653–1658) after the defeat of the Irish rebels would also plant New English in Ireland, known as the Protestant ascendency.

George Boole (1815–1864), the mathematician who invented Boolean algebra, spent the latter part of his life in Cork (city), Cork. The 19th century physicist George Johnstone Stoney, George Stoney introduced the idea and the name of the electron. He was the uncle of another notable physicist, George Francis FitzGerald, George FitzGerald. The Irish bardic system, along with the Gaels, Gaelic culture and learned classes, were upset by the plantations and went into decline. Among the last of the true bardic poets were Brian Mac Giolla Phádraig (c. 1580–1652) and

19th century


The Great Famine / An Górta Mór

Known as ''An Górta Mór'' ("The Great Hurt") in the Irish language, during the famine millions of Irish people died and emigrated during Ireland's largest famine. The famine lasted from 1845 - 1849, and it was worst in the year 1847, which became known as Black '47. The famine occurred due to the extremely impoverished Irish population's staple food the potato being infected with Blight, and the British administration appropriating all other crops and livestock to feed her armies abroad. This meant the crop failed and turned black. Starving people who tried to eat them would only vomit it back up soon afterwards. Soup kitchens were set up but made little difference. The British government produced little aid, only sending raw corn known as 'Peel's Brimstone' to Ireland. It was known by this name after the British Prime Minister at the time, Robert Peel, and the fact that many Irish weren't aware of how to cook corn. This led to little or no improvement. The British government set up workhouses which were disease-ridden (with cholera, TB and others) but they also failed as little food was available and many died on arrival as they were overworked. Some British political figures at the time saw the famine as a purge from God to exterminate the majority of the native Irish population. Irish people emigrated to escape the famine journeying predominantly to the east coast of the United States, especially Boston and New York City, New York, as well as Liverpool in England, Australia, Canada and New Zealand. Many records show the majority of Irish emigrants to Australia were in fact prisoners. A substantial proportion of these committed crimes in hopes of being extradited to Australia, favouring it to the persecution and hardships they endured in their homeland. Emigrants travelled on 'Coffin ship, Coffin Ships', which got their name from the often high mortality rates on board. Many died of disease or starved. Conditions on board were abysmal - tickets were expensive so stowaways were common, and little food stuff was given to passengers who were simply viewed as cargo in the eyes of the ship workers. Famous coffin ships include the Jeanie Johnston and the Dunbrody (1845), Dunbrody. There are many statues and memorials in Dublin, New York and other cities in memory of the famine. The Fields of Athenry is a famous song about the Great Famine and is often sung at national team sporting events in memory and homage to those affected by the famine. The Great Famine is one of the biggest events in Irish history and is ingrained in the identity on the nation to this day. It was a major factor in Irish nationalism, Irish Nationalism and Ireland's fight for Independence during subsequent rebellions, as many Irish people felt a stronger need to regain independence from British rule.


20th century

After the Irish War of Independence (1919–1921) the Anglo-Irish Treaty was signed which led to the formation of the independent Irish Free State (now the independent Republic of Ireland) which consisted of 26 of Ireland's 32 traditional counties. The remaining six counties in the northeast remained in the United Kingdom as

. It is predominantly religion, historical, and political differences that divide the two communities of (Irish nationalism, nationalism and Unionists (Ireland), unionism). Four polls taken between 1989 and 1994 revealed that when asked to state their national identity, over 79% of Northern Irish Protestants replied "British" or "Ulster" with 3% or less replying "Irish", while over 60% of Northern Irish Catholics replied "Irish" with 13% or less replying "British" or "Ulster". A survey in 1999 showed that 72% of Northern Irish Protestants considered themselves "British" and 2% "Irish", with 68% of Northern Irish Catholics considering themselves "Irish" and 9% "British". The survey also revealed that 78% of Protestants and 48% of all respondents felt "Strongly British", while 77% of Catholics and 35% of all respondents felt "Strongly Irish". 51% of Protestants and 33% of all respondents felt "Not at all Irish", while 62% of Catholics and 28% of all respondents felt "Not at all British".

, about 41.6% of the population are Protestant (19.1% Presbyterian, 13.7% Church of Ireland, 3.0% Methodist, 5.8% other Christian) whilst approximately 40.8% are Catholic as of 2011. The 31st International Eucharistic Congress was held in Dublin in 1932, that year being the supposed 1,500th anniversary of Saint Patrick's arrival. Ireland was then home to 3,171,697 Catholics, about a third of whom attended the Congress. It was noted in ''Time Magazine'' that the Congress' special theme would be "the Faith of the Irish". The massive crowds were repeated at Pope John Paul II's Pope John Paul II's visit to Ireland, Mass in Phoenix Park in 1979. The idea of faith has affected the question of Irish identity even in relatively recent times, apparently more so for Catholics and Irish-Americans. Today the majority of Irish people in the Republic of Ireland identify as Catholic, although church attendance has significantly dropped in recent decades. In

Irish identity

Thomas Davis (Young Irelander), Thomas Davis, a prominent Protestant Irish nationalists, Protestant Irish nationalist and founder of the Irish nationalist Young Ireland movement, identified the Irish as a Celtic nation. He estimated that ethnically, 5/6ths of the nation were either of Gaelic Irish-origin, or descended from returned Scottish Gaels (including much of the Ulster Scots people, Ulster Scots) and some Celtic Welsh (such as his own ancestors and those carrying surnames such as Walsh and Griffiths). As part of this he was a staunch supporter of the Irish language as the "national language". In regards to the Germanic minority in Ireland (of Norman and Anglo-Saxon origin) he believed that they could be assimilated into Irishness if they had a "willingness to be part of the Irish Nation".

This brought a further question for the future of Irish identity; whether Ireland was "closer to Boston than to Berlin:"


Irish diaspora

The Irish diaspora consists of Irish emigration, emigrants and their descendants in country, countries such as the United States, Great Britain, Canada, Australia, New Zealand, South Africa, and nations of the Caribbean such as Jamaica and Barbados. These countries all have large minorities of Irish descent, who in addition form the core of the Catholic Church in those countries. Many famous and influential figures have claimed Irish ancestry such as Che Guevara, Walt Disney, Barack Obama, John F.

Many Irish people were also transported to the island of Montserrat, to work as indentured servants, exiled prisoners or slaves. Unlike Ethnic groups of Africa, African chattel slaves, the majority of Irish labourers who were sent to Montserrat did so by personal choice. Some were Irish Confederate troops exiled by the English Parliamentarian Oliver Cromwell following the Irish Confederate Wars. The African slave population on the island attempted a rebellion against the Irish plantation owners on 17 March 1768. The date was chosen with the idea that the plantation owners would be distracted by St.Patrick's day festivities, but the plot was ultimately discovered and several of those involved were put to death. To this day, the Island celebrates St. Patrick's Day as a public holiday to commemorate the revolt and honour those who lost their lives. People of Irish descent also feature strongly in Latin America, especially in Argentina and important minorities in Brazil, Chile, and Mexico. In 1995, President Mary Robinson reached out to the "70 million people worldwide who can claim Irish descent". Today the diaspora is believed to contain an estimated 80 million people.The island history

There are also large Irish communities in some mainland European countries, notably in Spain, France and Germany. Between 1585 and 1818, over half a million Irish departed Ireland to serve in the wars on the Continent, in a constant emigration romantically styled the"Flight of the Wild Geese" and, before that, in the 'Flight of the Earls', just before the Plantation of Ulster. In the early years of the English Civil War, a French traveller remarked that the Irish "are better soldiers abroad than at home". Later, Irish brigades in France and Spain would fight in the War of the Spanish Succession, Wars of the Spanish and War of the Austrian Succession, Austrian Succession and the Napoleonic Wars. In the words of Field Marshal (United Kingdom), Field Marshal Arthur Wellesley, 1st Duke of Wellington, The 1st Duke of Wellington, the Irish-born 'Iron Duke', a notable representative of the Irish military diaspora, "Ireland was an inexhaustible nursery for the finest soldiers". The British Legions were units that Military career of Simón Bolívar, fought under Simón Bolívar against Spain for the independence of Colombia, Venezuela, Ecuador, and Peru. Venezuelans called them the Albion Legion. They were composed of over seven thousand volunteers, mainly Napoleonic Wars, Napoleonic War veterans from United Kingdom of Great Britain and Ireland, Great Britain and Ireland. Volunteers in the British Legion were motivated by a combination of both genuine political and mercenary motives. The most famous cause of emigration was the Irish Potato Famine, Great Famine of the late 1840s. A million are thought to have emigrated to Liverpool as a result of the famine. For both the Irish in Ireland and those in the resulting Irish diaspora, diaspora, the famine entered folk memory and became a rallying point for various Irish nationalism, nationalist movements. There are Afro-Caribbean people descended from Irish Caribbean, Irish immigrants in the Caribbean, especially on Barbados, Jamaica, and Montserrat. They often have Irish surnames, speak a form of Caribbean English influenced by the Irish vernacular and, in some cases, sing Irish songs. People of Irish descent are the second largest self-reported ethnic group in the United States, after German Americans. Nine of the signatories of the American Declaration of Independence were of Irish origin. Among them was the sole Catholic signatory, Charles Carroll of Carrollton, whose family were the descendants of Ely O'Carroll, an Irish prince who had suffered under Cromwell. At least twenty-five President of the United States, presidents of the United States have some Irish ancestral origins, including George Washington. Since John F. Kennedy took office in 1961, every American President (with the exception of Gerald Ford and Donald Trump) has had some Irish blood. An Irish-American, James Hoban, was the designer of the White House. John Barry (naval officer), Commodore John Barry, who was born in County Wexford, was the "Father of the United States Navy". In the mid-19th century, large numbers of Irish immigrants were conscripted into Irish regiments of the United States Army at the time of the Mexican–American War. The vast majority of the 4,811 Irish-born soldiers served in the U.S. Army, but some deserted to the Mexican Army, primarily to escape mistreatment by Protestant officers and the strong anti-Catholic discrimination in America. These were the ''San Patricios'', or Saint Patrick's Battalion—a group of Irish led by Galway-born John O'Riley, with some Roman Catholicism in Germany, German, Roman Catholicism in Scotland, Scottish and Roman Catholicism in the United States, American Catholics. They fought until their surrender at the decisive Battle of Churubusco, and were executed outside Mexico City by the American government on 13 September 1847. The battalion is commemorated in Mexico each year on 12 September. During the 18th and 19th centuries, 300,000 free emigrants and 45,000 convicts left Ireland to settle in Australia. Today, Australians of Irish descent are one of the largest self-reported ethnic groups in Australia, after English and Australian. In the 2006 Australian Census, Census, 1,803,741 residents identified themselves as having Irish ancestry either alone or in combination with another ancestry. However this figure does not include Australians with an Irish background who chose to nominate themselves as 'Australian' or other ancestries. The Australian embassy in Dublin states that up to thirty per cent of the population claim some degree of Irish ancestry. It is believed that as many as 30,000 Irish people emigrated to Argentina between the 1830s and the 1890s. This was encouraged by the clergy, as they considered a Catholic country, Argentina, preferable to a more Protestant United States. This flow of emigrants dropped sharply when assisted passage to Australia was introduced at which point the Argentine government responded with their own scheme and wrote to Irish bishops, seeking their support. However, there was little or no planning for the arrival of a large number of immigrants, no housing, no food. Many died, others made their way to the United States and other destinations, some returned to Ireland, a few remained and prospered. Thomas Croke Archbishop of Cashel, said: "I most solemnly conjure my poorer countrymen, as they value their happiness hereafter, never to set foot on the Argentine Republic however tempted to do so they may be by offers of a passage or an assurance of comfortable homes." Some famous Argentines of Irish descent and Irish people who settled in Argentina include Che Guevara, former president Edelmiro Julián Farrell, and admiral William Brown (admiral), William Brown. There are people of Irish descent all over South America, such as the Chilean liberator Bernardo O'Higgins and the Peruvian photographer Mario Testino. Although some Irish retained their surnames intact, others were assimilated into the Spanish vernacular. The last name ''O'Brien'', for example, became ''Obregón''. People of Irish descent are also one of the largest self-reported ethnic groups in Canada, after English Canadian, English, French Canadian, French and Scottish Canadians. As of 2006, Irish Canadians number around 4,354,155.
