Irish Briton

Irish migration to Great Britain has occurred from the earliest recorded history to the present. There has been a continuous movement of people between the islands of Ireland and Great Britain due to their proximity. This tide has ebbed and flowed in response to politics, economics and social conditions of both places.

Today, millions of residents of Great Britain are either from Ireland or are entitled to an Irish passport due to having a parent or grandparent who was born in Ireland. The modern era of Irish migration has also seen non-indigenous Asian Irish and black Irish people move to Britain. It is estimated that as many as six million people living in the UK have at least one Irish grandparent (around 10% of the UK population).

The Irish diaspora ( ga, Diaspóra na nGael) refers to Irish people and their descendants who live outside Ireland. This article refers to those who reside in Great Britain, the largest island and principal territory of the United Kingdom.

Migration eras

Medieval

Post the End of Roman rule in Britain, significant Irish settlement of western Britain took place.

The Déisi recorded as having founded the Gwynedd (Anglesea) and Dyfed (Pembrokeshire) colonies, with contemporary Ogham inscriptions identifying the genealogies of the colonists, and later echoed in the 8th century, Old Irish work, The Expulsion of the Déisi.

Similarly the 'traditional' view is that Gaelic language and culture was brought to Scotland, probably in the 4th century, by settlers from Ireland, who founded the Gaelic kingdom of Dál Riata on Scotland's west coast. This is based mostly on medieval writings from the 9th and 10th centuries. However, recently some archeologists have argued against this view, saying that there is no archeological or placename evidence for a migration or a takeover by a small group of elites.Campbell, Ewan.
Were the Scots Irish?
in ''Antiquity'' #75 (2001). Due to the growth of Dál Riata, in both size and influence, Scotland became almost wholly Gaelic-speaking. However, in the Lowlands – which had been the northernmost part of the Kingdom of Northumbria, the Northumbrian language remained dominant, and formed the basis of the Scots language. While Scots gradually became more and more widespread, Gaelic remained the dominant language of the Highlands into the 19th century.

Before and during the Gregorian mission of 596 AD, Irish Christians such as Columba (521–97), Buriana, Diuma, Ceollach, Saint Machar, Saint Cathan, Saint Blane, Jaruman, Wyllow, Kessog, St Govan, Donnán of Eigg, Foillan and Saint Fursey began the conversion of the English and Pictish peoples. Modwenna and others were significant in the following century.

Some English monarchs, such as Oswiu of Northumbria (c. 612 – 15 February 670), Aldfrith (died 704 or 705) and Harold Godwinson (died 1066) were either raised in or sought refuge in Ireland, as did Welsh rulers such as Gruffudd ap Cynan. Alfred the Great may have spent some of his childhood in Ireland.

In the year 902 Norsemen who had been forced out of Ireland were given permission by the English to settle in Wirral, in the north west of England. An Irish historical record known as " The Three Fragments" refers to a distinct group of settlers living among these Vikings as "Irishmen". Further evidence of this Irish migration to Wirral comes from the name of the village of Irby in Wirral, which means "settlement of the Irish", and St Bridget's church, which is known to have been founded by "Vikings from Ireland".

The island of Ireland was itself claimed as an Ecclesiastical fief, via the forged, mid 8th century, Donation of Constantine, with the feudal Lordship of Ireland later leased to Henri Curtmantle de Le Mans and his heirs, by Pope Alexander III's, 1171 grant, resulting in the presence and settlement of Irish traders and seamen in English and Welsh ports, as well as the establishment of The Pale, on the island, the Irish settlers being subject to a poll tax, from 1440; in 1542, Henry VIII, following his excommunication, would have the Irish Parliament create the Kingdom, with himself elected as King, and subsequently through offering English titles, and ecclesiastical lands, in a surrender and regrant process, would offer Irish clan chiefs, property and political power, in England, as well as Ireland. In 1555, Pope Paul IV, would confirm the existence of the Irish Kingdom, and that it was to be held in personal union with the Kingdom of England, via a Papal bull. A personal Union that would later include the Kingdom of Scotland, and between 1707 and 1800, the politically united Kingdom of Great Britain. The Irish Parliament and Kingdom would be politically united with Great Britain as the United Kingdom of Great Britain and Ireland, between 1801 and 1922, through the Acts of Union 1800. Today, Ireland is divided between the independent Republic of Ireland and Northern Ireland, a constituent of the United Kingdom.

Irish people who made Britain their home in the later medieval era included Aoife MacMurrough, Princess of Leinster (1145–88), the poet Muireadhach Albanach (fl. 1213), the lawyer William of Drogheada (died 1245), Máel Muire Ó Lachtáin (died 1249), Malachias Hibernicus (fl. 1279–1300), Gilbert Ó Tigernaig (died 1323), Diarmait MacCairbre (executed 1490) and Germyn Lynch (fl. 1441–1483), all of whom made successful lives in the various kingdoms of Britain.

16th to 18th centuries

Historically, Irish immigrants to the United Kingdom in the eighteenth and nineteenth centuries were considered over-represented amongst those appearing in court. However, research suggests that policing strategy may have put immigrants at a disadvantage by targeting only the most public forms of crime, while locals were more likely able to engage in the types of crimes that could be conducted behind locked doors. An analysis of historical courtroom records suggests that despite higher rates of arrest, immigrants were not systematically disadvantaged by the British court system in the eighteenth and nineteenth centuries.

Some notable people born in Ireland who settled in Great Britain between the 16th and 19th centuries:

* Richard Burke, 4th Earl of Clanricarde, died 1635.
* Robert Boyle, FRS, died 1691.
* Laetitia Pilkington, died 1750.
* Richard Brinsley Sheridan
* George Monro (British Army officer), 1700–57.
* Patrick Brontë, 1777–1861.
* Arthur Wellesley, 1st Duke of Wellington
* Thomas Moore, died 1852.
* Bram Stoker, author of ''Dracula''
* Oliver Goldsmith, author of ''The Deserted Village''
* Edmund Burke, politician, reformer, writer
* Mary Burns
* Robert Tressell, author of The Ragged Trousered Philanthropists

19th century

The most significant exodus followed the worst of a series of potato crop failures in the 1840s – the Great Irish Famine. It is estimated that more than one million people died and almost the same again emigrated. A further wave of emigration to England also took place between the 1930s, and 1960s by Irish escaping poor economic conditions following the establishment of the Irish Free State. This was furthered by the severe labour shortage in Britain during the mid-20th century, which depended largely on Irish immigrants to work in the areas of construction and domestic labour. The extent of the Irish contribution to Britain's construction industry in the 20th century may be gauged from Sir William MacAlpine's 1998 assertion that the contribution of the Irish to the success of his industry had been 'immeasurable'. This statement by a member of the British upper class illustrates how Irish migrant labour was regularly employed to discipline and weaken organised English labour unions at the same time as disparaging the contribution of the latter to the development of their own nation. Of this process the German-born philosopher Karl Marx wrote in 1870:

"Ireland constantly sends her own surplus to the English labour market, and thus forces down wages and lowers the material and moral position of the English working class... This antagonism is the secret of the impotence of the English working class, despite its organisation. It is the secret by which the capitalist class maintains its power. And the latter is quite aware of this."

Ireland's population fell from more than 8 million to just 6.5 million between 1841 and 1851. A century later it had dropped to 4.3 million. By the late 19th century, emigration was heaviest from Ireland's most rural southern and western counties. Cork, Kerry, Galway, Mayo, Sligo, Tipperary and Limerick alone provided nearly half of Ireland's emigrants. Some of this movement was temporary, made up of seasonal harvest labourers working in Britain and returning home for winter and spring.

20th to 21st centuries

By the mid-1930s, Great Britain was the choice of many who had to leave Ireland. Britain's wartime economy (1939–45) and post-war boom attracted many Irish people to expanding cities and towns such as London, Liverpool, Manchester, Birmingham, Glasgow and Luton. Prior to the 2000s financial crisis, ongoing sectarian violence and its economic aftermath was another major factor for immigration.

According to the UK 2001 Census, white Irish-born residents make up 1.2% of those living in England and Wales. In 1997, the Irish Government in its ''White Paper on Foreign Policy'' claimed that there were around two million Irish citizens living in Britain. The 2001 Census also showed that Irish people are more likely to be employed in managerial or professional occupations than those classed as "White British".

As a result of the Irish financial crisis, emigration from Ireland rose significantly. Data published in June 2011 showed that Irish emigration to Britain had risen by 25 per cent to 13,920 in 2010.

Some notable people born in Ireland who settled in Great Britain between the 20th and 21st centuries include:

Irish broadcasters

BBC broadcaster Sir Terry Wogan moved to Buckinghamshire, England in 1969, acquiring British citizenship and a knighthood in 2005, and remained resident in the UK until his death in 2016. Comedians Ed Byrne and Dara Ó Briain have relocated to Britain from Ireland, and regularly feature on British television.

Black and Asian communities

Since the 1970s some UK organisations, sections of media, and government departments have defined Black, Asian and minority ethnic (BAME) in anti-racist efforts and general demography. There are several notable Irish migrants to Great Britain who are people of colour, or who might otherwise be considered part of BAME communities. This includes emigrants from Ireland from the black Irish community, as well as Asian Irish people.

Irish musician and singer Phil Lynott settled in Surrey, England after the commercial success of his Dublin-formed band Thin Lizzy. Lynott, who died in 1986, was mixed raced and had British Guianan ancestry. Irish actor Christopher Simpson was moved to London, England as child in 1981. Simpson is of Irish and Rwandan descent.

Irish footballer Darren Randolph, who has spoken of his experiences growing up black in Ireland, moved to Britain permanently after joining London team Charlton Athletic F.C. in 2003, and has since remained in English football. Model and actress Layla Flaherty relocated to Liverpool, England in 2006. Flaherty, who has Irish and African American heritage, has appeared in UK-based E4 productions, such as '' Desperate Scousewives''. Also relocating to England in 2006, Ethiopian-Irish actress Ruth Negga has appeared in films, as well as RTÉ and BBC series. In 2018, Negga, who has been Academy Award-nominated, was featured in the Evening Standard's ''Progress 1000'' list, which claims to chart the careers of London's most influential people. Irish presenter Liz Bonnin has also relocated to London. Bonnin, who has Indian, Portuguese, and French- Martiniquan heritage moved to Britain after establishing a science-based broadcasting career with the BBC
