Question: When was a free-travel area created between Ireland and the part of the UK the city where Billy Giles died is located?

<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> 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. <P0-S4> However, since the partition of Ireland, an informal free-travel area had existed across the region. <SEP> <P1-S0> the united kingdom of great britain and northern ireland, commonly known as the united kingdom (uk) or britain, is a sovereign country lying off the north - western coast of the european mainland. <P1-S1> the united kingdom includes the island of great britain, the north - eastern part of the island of ireland and many smaller islands. <P1-S2> northern ireland is the only part of the united kingdom that shares a land border with another sovereign state‍ -- ‌the republic of ireland. <P1-S3> apart from this land border, the united kingdom is surrounded by the atlantic ocean, with the north sea to its east, the english channel to its south and the celtic sea to its south - south - west, giving it the 12th - longest coastline in the world. <P1-S4> the irish sea lies between great britain and ireland. <P1-S5> with an area of 242,500 square kilometres (93,600 sq mi), the united kingdom is the 78th - largest sovereign state in the world. <P1-S6> it is also the 22nd-most populous country, with an estimated 66.0 million inhabitants in 2017. <SEP> <P2-S0> Billy Giles (3 September 1957, Belfast – 25 September 1998, Belfast) was an Ulster Volunteer Force volunteer who later became active in politics following his release from the Maze Prison in 1997 after serving 14 years of a life sentence for murder. <SEP> <P3-S0> 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. <P3-S1> CAMRA maintains a "National Inventory" of historical notability and of architecturally and decoratively notable pubs. <SEP> <P4-S0> ireland, the united kingdom and the three crown dependencies are all parliamentary democracies, with their own separate parliaments. <P4-S1> all parts of the united kingdom return members to parliament in london. <P4-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. <P4-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. <P4-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.) <P4-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.
