Question: When were travel restrictions relaxed between Ireland and the country where the book Judith Hearne is set?

full_context: Document 1: British Isles: The British Isles are a group of islands off the north-western coast of continental Europe that consist of the islands of Great Britain, Ireland and over six thousand smaller isles. Situated in the North Atlantic, the islands have a total area of approximately 315,159 km2, and a combined population of just under 70 million. Two sovereign states are located on the islands: Ireland (which covers roughly five-sixths of the island with the same name) and the United Kingdom of Great Britain and Northern Ireland. The British Isles also include three Crown Dependencies: the Isle of Man and, by tradition, the Bailiwick of Jersey and the Bailiwick of Guernsey in the Channel Islands, although the latter are not physically a part of the archipelago.
Document 2: British Isles: Ireland and the United Kingdom are both part of the European Union (EU). The Crown Dependencies are not a part of the EU however do participate in certain aspects that were negotiated as a part of the UK's accession to the EU. Neither the United Kingdom or Ireland are part of the Schengen area, that allow passport-free travel between EU members states. However, since the partition of Ireland, an informal free-travel area had existed across the region. In 1997, this area required formal recognition during the course of negotiations for the Amsterdam Treaty of the European Union and is now known as the Common Travel Area.
Document 3: Pub: The Lost Pubs Project listed 28,095 closed pubs on 21 April 2015, with photographs of many. In 2015 the rate of pub closures came under the scrutiny of Parliament in the UK, with a promise of legislation to improve relations between owners and tenants.
Document 4: To Kill a Mockingbird: Reaction to the novel varied widely upon publication. Literary analysis of it is sparse, considering the number of copies sold and its widespread use in education. Author Mary McDonough Murphy, who collected individual impressions of To Kill a Mockingbird by several authors and public figures, calls the book, "an astonishing phenomenon". In 2006, British librarians ranked the book ahead of the Bible as one "every adult should read before they die". It was adapted into an Oscar-winning film in 1962 by director Robert Mulligan, with a screenplay by Horton Foote. Since 1990, a play based on the novel has been performed annually in Harper Lee's hometown of Monroeville, Alabama.
Document 5: Pub: Many of London's pubs are known to have been used by famous people, but in some cases, such as the association between Samuel Johnson and Ye Olde Cheshire Cheese, this is speculative, based on little more than the fact that the person is known to have lived nearby. However, Charles Dickens is known to have visited the Cheshire Cheese, the Prospect of Whitby, Ye Olde Cock Tavern and many others. Samuel Pepys is also associated with the Prospect of Whitby and the Cock Tavern.
Document 6: Pub: In Europe, it is the provision of accommodation, if anything, that now distinguishes inns from taverns, alehouses and pubs. The latter tend to provide alcohol (and, in the UK, soft drinks and often food), but less commonly accommodation. Inns tend to be older and grander establishments: historically they provided not only food and lodging, but also stabling and fodder for the traveller's horse(s) and on some roads fresh horses for the mail coach. Famous London inns include The George, Southwark and The Tabard. There is however no longer a formal distinction between an inn and other kinds of establishment. Many pubs use "Inn" in their name, either because they are long established former coaching inns, or to summon up a particular kind of image, or in many cases simply as a pun on the word "in", as in "The Welcome Inn", the name of many pubs in Scotland.
Document 7: The Tin Flute: The Tin Flute (original French title "Bonheur d'occasion", "secondhand happiness"), Gabrielle Roy’s first novel, is a classic of Canadian fiction. Imbued with Roy’s brand of compassion and understanding, this story focuses on a family in the Saint-Henri slums of Montreal, its struggles to overcome poverty and ignorance, and its search for love.
Document 8: British Isles: There are two sovereign states in the isles: Ireland and the United Kingdom of Great Britain and Northern Ireland. Ireland, sometimes called the Republic of Ireland, governs five sixths of the island of Ireland, with the remainder of the island forming Northern Ireland. Northern Ireland is a part of the United Kingdom of Great Britain and Northern Ireland, usually shortened to simply the United Kingdom, which governs the remainder of the archipelago with the exception of the Isle of Man and the Channel Islands. The Isle of Man and the two states of the Channel Islands, Jersey and Guernsey, are known as the Crown Dependencies. They exercise constitutional rights of self-government and judicial independence; responsibility for international representation rests largely upon the UK (in consultation with the respective governments); and responsibility for defence is reserved by the UK. The United Kingdom is made up of four constituent parts: England, Scotland and Wales, forming Great Britain, and Northern Ireland in the north-east of the island of Ireland. Of these, Scotland, Wales and Northern Ireland have "devolved" governments meaning that they have their own parliaments/assemblies and are self-governing with respect to certain areas set down by law. For judicial purposes, Scotland, Northern Ireland and England and Wales (the latter being one entity) form separate legal jurisdiction, with there being no single law for the UK as a whole.
Document 9: British Isles: Ireland, the United Kingdom and the three Crown Dependencies are all parliamentary democracies, with their own separate parliaments. All parts of the United Kingdom return members to parliament in London. In addition to this, voters in Scotland, Wales and Northern Ireland return members to a parliament in Edinburgh and to assemblies in Cardiff and Belfast respectively. Governance in the norm is by majority rule, however, Northern Ireland uses a system of power sharing whereby unionists and nationalists share executive posts proportionately and where the assent of both groups are required for the Northern Ireland Assembly to make certain decisions. (In the context of Northern Ireland, unionists are those who want Northern Ireland to remain a part of the United Kingdom and nationalists are those who want Northern Ireland join with the rest of Ireland.) The British monarch is the head of state for all parts of the isles except for the Republic of Ireland, where the head of state is the President of Ireland.
Document 10: The Voyage Out: Literary scholar Phyllis Rose writes in her introduction to the novel, ``No later novel of Woolf's will capture so brilliantly the excitement of youth. ''And also the excitement and challenge of life.`` It's not cowardly to wish to live,'' says one old man at the end of the book. ``It's the very reverse of cowardly. Personally, I'd like to go on for a hundred years... Think of all the things that are bound to happen! ''
Document 11: Pub: The highwayman Dick Turpin used the Swan Inn at Woughton-on-the-Green in Buckinghamshire as his base. In the 1920s John Fothergill (1876–1957) was the innkeeper of the Spread Eagle in Thame, Berkshire, and published his autobiography: An Innkeeper's Diary (London: Chatto & Windus, 1931). During his idiosyncratic occupancy many famous people came to stay, such as H. G. Wells. United States president George W. Bush fulfilled his lifetime ambition of visiting a 'genuine British pub' during his November 2003 state visit to the UK when he had lunch and a pint of non-alcoholic lager (Bush being a teetotaler) with British Prime Minister Tony Blair at the Dun Cow pub in Sedgefield, County Durham in Blair's home constituency. There were approximately 53,500 public houses in 2009 in the United Kingdom. This number has been declining every year, so that nearly half of the smaller villages no longer have a local pub.
Document 12: British Isles: The Northern Ireland Peace Process has led to a number of unusual arrangements between the Republic of Ireland, Northern Ireland and the United Kingdom. For example, citizens of Northern Ireland are entitled to the choice of Irish or British citizenship or both and the Governments of Ireland and the United Kingdom consult on matters not devolved to the Northern Ireland Executive. The Northern Ireland Executive and the Government of Ireland also meet as the North/South Ministerial Council to develop policies common across the island of Ireland. These arrangements were made following the 1998 Good Friday Agreement.
Document 13: Pub: CAMRA maintains a "National Inventory" of historical notability and of architecturally and decoratively notable pubs. The National Trust owns thirty-six public houses of historic interest including the George Inn, Southwark, London and The Crown Liquor Saloon, Belfast, Northern Ireland.
Document 14: Judith Hearne: Set in Belfast in the 1950s, "Judith Hearne" has been described as "a sensitive study of a middle-aged alcoholic woman in drab Belfast and her desperate last attempts at finding love and companionship". Ann Leary, reviewing the book for NPR, calls it "a short book about a lifetime of longing" and says "Moore uses brilliant economy in his writing; it's as if words are as scarce and precious as sunshine in this gloomy section of postwar Belfast". According to Colm Tóibín, the book "is full of Joycean moments... it takes from ‘Clay’, the most mysterious story in Dubliners, the idea of a single, middle-aged woman visiting a family and finding both comfort and humiliation there". Robert Fulford, writing in Canada's "The Globe and Mail", describes it as "a bleak post-Catholic novel" that depicts "a desolate life, stripped of warming humanity".
Document 15: Journey Through a Small Planet: In "Journey Through a Small Planet" (1972), the writer Emanuel Litvinoff recalls his working-class Jewish childhood in the East End of London: a small cluster of streets right next to the city, but worlds apart in culture and spirit. With vivid intensity Litvinoff describes the overcrowded tenements of Brick Lane and Whitechapel, the smell of pickled herring and onion bread, the rattle of sewing machines and chatter in Yiddish. He also relates stories of his parents, who fled from Russia in 1914, his experiences at school and a brief flirtation with Communism. Unsentimental, vital and almost dream like, this is a masterly evocation of a long-vanished world.
