The CTA was suspended at the outbreak of war in 1939 and travel restrictions were introduced between the islands of Great Britain and Ireland.  This meant that travel restrictions even applied to persons travelling within the United Kingdom when travelling from Northern Ireland to other countries in the United Kingdom. This document contains the following information: Agreement between the United Kingdom and Ireland: Dublin, 22 March 2007. The Ireland/Northern Ireland Protocol contains an obligation to maintain the Common Travel Area (GCTA), which has existed since the creation of the Irish Free State in 1922, for most of the period. The CTA allows the free movement of British and Irish citizens between the United Kingdom, Ireland, the Channel Islands and the Isle of Man and provides access to various government services in each country. The agreement obliges the two governments to continue their cooperation through the CTA, to align their lists of visa-free countries, to develop an electronic border management system,to participate in the joint use of data to combat the “abuses” of the CTA and to work towards the establishment of a “fully common visa for short-term stays”.    The EU and the UNITED Kingdom have agreed on continued funding for the PEACE programme. Although the British government had wanted Ireland to dominate the whole country since 1914, the British Parliament considered that in 1921 it could grant full independence to the whole of Ireland, without provoking major religious violence between predominantly Protestant Irish Unionists and predominantly Catholic Irish nationalists. [Citation required] At that time, there were Unionists throughout the country, but they were concentrated in the northeast and their parliament sat for the first time on June 7, 1921. An insurrection on their part against the domination of the homeland would have been an insurrection against the “mother county” and a civil war in Ireland. (See Ulster Volunteers). Dominion`s status for 26 counties, with a division for the six counties that the Unionists could control for convenient, seemed to be the best compromise. Workers also have the right to access social benefits on the same basis as citizens of the state where they work.
The UK Government and Ireland have entered into a bilateral agreement to ensure that these rights are also protected after the UK`s withdrawal from the EU.  These deep networks and freedom of movement advance an economic and trade relationship of $1.1 billion per week between Ireland and the United Kingdom. Our desire to maintain such close relations will not change, although the level and intensity of these bilateral relations will inevitably be marked by future agreements between the EU and the UNITED Kingdom. The closer the relationship between the EU and the UK, the easier it will be to keep our two countries close. Like its previous predecessors, the 2011 agreement is non-binding, with the eighth clause stating that the agreement “is not intended to create legally binding obligations or confer a right, right or benefits on a private or public person or party.”  On 15 December, Robert Barton was asked by Kevin O`Higgins about his notes on Lloyd George`s statement on the signing of the agreement or on the extension of the war: “Did Mr. Lloyd George choose Mr. Barton as the left wing of the delegation and said, “The man who is against peace can now and always bear the responsibility for a terrible and immediate war?” Barton replied, “What he said was that the signature and recommendation of each member of the delegation was necessary, or that a war would follow immediately, and that the responsibility for this war should lie directly with those who refused to sign the treaty.”
