Definicija: By the Schengen Agreement signed on 14 June 1985, Belgium, France, Germany, Luxembourg and the Netherlands agreed that they would gradually remove controls at their common borders and introduce freedom of movement for all nationals of the signatory EU Member States, other Member States or third countries. The Schengen Convention supplements the Agreement and lays down the arrangements and safeguards for implementing freedom of movement. The Agreement and the Convention, the rules adopted on that basis and the related agreements together form the "Schengen acquis". Since 1999, this has formed part of the institutional and legal framework of the European Union by virtue of a protocol to the Treaty of Amsterdam.

Opomba: As of January 2010, EU Member States which are part of the Schengen Area are Austria, Belgium, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Italy, Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Poland, Portugal, Slovak Republic, Slovenia, Spain and Sweden. This means that the other EU Member States (i.e. Bulgaria, Cyprus, Ireland, Romania and the United Kingdom) are not part of Schengen. Whilst Iceland, Liechtenstein, Norway and Switzerland are not EU Member States, they have signed an Agreement on Association in order to be associated with the implementation, application and development of the Schengen acquis.
