This was the Schengen Agreement, named after a village in Luxembourg
Full convention came into practical effect a decade later, also covering Italy, Spain, Portugal and Greece
Created single external border, harmonised some rules on asylum and visas, enhanced police and judicial co-operation and established shared information database
