The signatory states of the Schengen Agreement (France, Germany, Belgium, Luxembourg and the Netherlands) decided, in June 1985, to create a territory without internal borders – the Schengen area. Then, in 1995, the Convention implementing the Schengen Agreement abolished checks at the internal borders of the signatory states and created a single external border. In 1997, the Amsterdam Treaty incorporated into the framework of the EU the Schengen Agreements and the rules adopted under them. The Schengen agreement was, therefore, a huge step towards EU integration. In fact, it has been seen as one of the main pillars of the EU beside the euro. The North Africa’s unrests and the massive displacement of people, particularly from Tunisia and Libya, have put the Schengen system under increasing strain, as thousands of migrants and refugees have arrived in Italy and Malta.
