The Schengen Area is a group of European countries that have abolished passport and other types of border control at their mutual borders. This agreement allows for free movement of people, making travel easier for residents and tourists alike. Currently, it includes 26 countries, primarily in Europe, which have agreed to common visa policies and border management. Established in 1995, the Schengen Agreement promotes cooperation among member states to enhance security while facilitating travel. It has significantly impacted tourism and trade, allowing individuals to move freely across borders without the need for frequent checks, thus fostering a sense of unity among European nations.
