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

<P0-S0> Ireland and the United Kingdom are both part of the European Union (EU). <P0-S1> 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. <P0-S2> Neither the United Kingdom or Ireland are part of the Schengen area, that allow passport-free travel between EU members states. <P0-S3> However, since the partition of Ireland, an informal free-travel area had existed across the region. <P0-S4> 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. <SEP> <P1-S0> 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". <P1-S1> 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". <P1-S2> 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". <P1-S3> 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". <SEP> <P2-S0> CAMRA maintains a "National Inventory" of historical notability and of architecturally and decoratively notable pubs. <P2-S1> 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. <SEP> <P3-S0> ireland, the united kingdom and the three crown dependencies are all parliamentary democracies, with their own separate parliaments. <P3-S1> all parts of the united kingdom return members to parliament in london. <P3-S2> 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. <P3-S3> 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. <P3-S4> (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.) <P3-S5> 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. <SEP> <P4-S0> northern ireland was created in 1921, when ireland was partitioned between northern ireland and southern ireland by the government of ireland act 1920. unlike southern ireland, which would become the irish free state in 1922, the majority of northern ireland's population were unionists, who wanted to remain within the united kingdom. <P4-S1> most of these were the protestant descendants of colonists from great britain. <P4-S2> however, a significant minority, mostly catholics, were nationalists who wanted a united ireland independent of british rule. <P4-S3> today, the former generally see themselves as british and the latter generally see themselves as irish, while a distinct northern irish or ulster identity is claimed both by a large minority of catholics and protestants and by many of those who are non-aligned.
