It takes its name from the City of Schengen in Luxembourg, where the agreement was signed in 1985. It came into force in 1995. This is because Britain is not part of the Schengen area, which was concluded as a result of an agreement in a symbolic village on the border with three countries. Differences of opinion between Member States led to a deadlock in the abolition of border controls within the Community, but in 1985 five of the ten Member States at the time – Belgium, France, Luxembourg, the Netherlands and West Germany – signed an agreement on the phasing out of border controls. The agreement was signed on the princess Marie-Astrid boat in Moselle, near the city of Schengen, where the territories of France, Germany and Luxembourg meet. Three of the signatories, Belgium, Luxembourg and the Netherlands, had already abolished common border controls under the Benelux Economic Union. [Citation required] Now that the Schengen Agreement is part of the Community acquis, it has lost to the EU Member States the status of a treaty which could only be amended in accordance with its terms. Instead, changes are made in accordance with the EU`s legislative procedure under the EU treaties.  Ratification by the former signatory states is not necessary to amend or repeal all or part of the previous Schengen acquis.
 Acts setting out the conditions for accession to the Schengen area are now adopted by a majority of the EU`s legislative bodies. The new EU Member States do not sign the Schengen Agreement as such, but are required to implement the Schengen rules within the framework of existing EU legislation, which any new entrant must accept. [Citation required] This means that Schengen Member States that were not part of the EU have few formally binding options to influence the development and development of Schengen rules; their options are effectively reduced to approval or exit from the agreement. However, consultations are being held with the countries concerned prior to the adoption of certain new provisions.  The attacks in Paris on 13 November, which killed 130 people, have led to an urgent change of mentality in the Schengen Agreements. The United Kingdom and Ireland participated in certain aspects of the Schengen Agreement from 2000 and 2002, such as the Schengen Information System (SIS). In December 1996, two non-EU states, Norway and Iceland, signed an association agreement with the countries that signed the Schengen accession agreement.
