Repartition of Ireland

A de facto border was established by the Government of Ireland Act 1920, in which the British Government establised (or attempted to establish) two devolved administrations within the United Kingdom, Northern Ireland and Southern Ireland. The former consisted of north-easterly six of the nine counties of Ulster; the latter of the remaining 26 (including three of Ulster). In 1925, the Irish Boundary Commission was established to consider whether a more appropriate border might be drawn. On 7 November 1925 an English Conservative newspaper, The Morning Post, published leaked notes of the negotiations, including a draft map. The overall effects of the Boundary Commission's recommendations would have been the transfer of 286 square miles to the Free State and 77 square miles to Northern Ireland.[2] The leaked report included, accurately, the Boundary Commission recommendation that parts of east Donegal would be transferred to Northern Ireland. Only 1 in every 25 Northern Irish Catholics would have been placed under Free State rule.[2] The Boundary Commission's recommendations would have shortened the border by 51 miles (approx. 18%).[2] The press leak effectively ended the Commission's work.[3][4] The three governments, however, determined another agreement on 6 December 1925 (subject to parliamentary approval) which confirmed the existing boundary of Northern Ireland, along with other matters.[5] This new agreement was approved by the Dáil (the lower house of the Free State parliament) by a vote of 71 to 20,[6] and in Westminster by the "Ireland (Confirmation of Agreement) Act" that was passed unanimously by the British parliament on 8–9 December.[7][8] The Agreement was then formally registered with the League of Nations on 8 February 1926.

The 1937 Constitution of Ireland described the whole island of Ireland as the "National Territory", but this irredentist claim was dropped by the Nineteenth Amendment that permitted the Irish government to ratify the 1998 Good Friday Agreement.

To the left is a map showing the religious divisions in Ireland in 1991 (based on the census of both states, the United Kingdom and the Census#Republic of Ireland). Areas in which the majority of the population was Protestant/unionist/loyalist are shown in green, whilst areas in which the majority of the population was Catholic/nationalist/republican are shown in blue. To the right is an image of a proposed settlement of a repartitioned island. Many areas of Northern Ireland would have been ceded to the RoI. Those areas which would remain part of Northern Ireland (and thus stay in the UK) are shown in green, while those areas which would have formed the enlarged Republic are shown in blue. Red lines denote county boundaries.

Repartition resurfaced as an option with the start of the Troubles. In 1972, the Conservative MP Julian Critchley published a pamphlet for the Bow Group advocating repartition, titled Ireland: A New Partition. Civil servants in London prepared a "last-ditch" plan in 1974, for possible use in the event of a full-scale civil war, which would have seen Roman Catholic inhabitants of the northeast forcibly moved to Fermanagh, southern Londonderry, Tyrone, South Armagh and South Down. Protestant inhabitants of those areas would have been moved into North Down, Antrim, Northern Londonderry and North Armagh. The nationalist areas would then have been ceded to the Republic of Ireland. An alternative plan simply involved "moving individual Catholics from their homes in Northern Ireland to new homes in the Republic". The plan was kept secret at the time and was revealed in 2002.[9][10] In a 2006 essay, Garret FitzGerald, the Republic's Foreign Minister in 1974, revealed his government's opinions on repartition or a complete British withdrawal.[11]

Pollsters have rarely asked the population of Northern Ireland about their attitudes to repartition but it was asked twice in the early 1980s. In June 1981 and February 1982, the percentages of Protestants agreeing to repartition was 9% and 8%; the percentages for Catholics were 22% and 24%.[12]

Research by Paul Compton of Queen's University of Belfast (QUB) fed into a secret 1984 briefing paper prepared by the Northern Ireland Office for then-Prime Minister Margaret Thatcher, which examined various repartition schemes, the most extensive transferring to the Republic half of Northern Ireland's territory and one-third of its population, with West Belfast a "walled ghetto" enclave.[13] The plans were quickly dismissed as impractical and politically unworkable.[13] Later in 1984, then-Taoisaeach Garret FitzGerald spoke against repartition as reinforcing partition.[13]

In 1986, QUB economic historian Liam Kennedy published a book-length study of repartition called Two Ulsters: A Case for Repartition.

During the late 1980s, repartition was repeatedly proposed by assorted individuals and small groups. It became popular in some sections of the Ulster nationalist movement, who were keen to establish a state with a large Protestant majority. Conversely, the Ulster Movement for Self-Determination proposed an enlarged state of Ulster, including all the historic province. This state, were it to have been created, would have had almost equal numbers of nationalists and unionists.

In early January 1994, the Ulster Defence Association (UDA) released a document calling for repartition combined with ethnic cleansing, with the goal of making Northern Ireland wholly Protestant.[14] The plan was to be implemented should the British Army withdraw from Northern Ireland. The vastly Irish Catholic and nationalist areas would be handed over to the Republic, and those left stranded in the "Protestant state" would be "expelled, nullified, or interned".[14] The story was printed in the Sunday Independent newspaper on 16 January.[15] The "doomsday plan" was based on the work of Liam Kennedy, though he had not proposed ethnic cleansing.[14] Sammy Wilson, then press officer for the Democratic Unionist Party and later the MP for East Antrim, spoke positively of the document, calling it a "valuable return to reality" and lauded the UDA for "contemplating what needs to be done to maintain our separate Ulster identity".[14]

Margaret Thatcher said in 1998 that when it became obvious that the Anglo-Irish Agreement was in trouble, she too had considered repartition, although she had not pursued the idea.[16]
