Schengen Area in the context of "Member state of the European Union"

A supranational union is a type of international organization and political union that is empowered to directly exercise some of the powers and functions otherwise reserved to states. A supranational organization involves a greater transfer of or limitation of state sovereignty than other kinds of international organizations.

The European Union (EU) has been described as a paradigmatic case of a supranational organization, as it has deep political, economic and social integration, which includes a common market, joint border control, a supreme court, and regular popular elections.

Borders are generally defined as geographical boundaries, imposed either by features such as oceans and terrain, or by political entities such as governments, sovereign states, federated states, and other subnational entities. Political borders can be established through warfare, colonization, or mutual agreements between the political entities that reside in those areas.

Some borders—such as most states' internal administrative borders, or inter-state borders within the Schengen Area—are open and completely unguarded. Most external political borders are partially or fully controlled, and may be crossed legally only at designated border checkpoints; adjacent border zones may also be controlled. For the purposes of border control, airports and seaports are also classed as borders. Most countries have some form of border control to regulate or limit the movement of people, animals, and goods into and out of the country. Under international law, each country is generally permitted to legislate the conditions that have to be met in order to cross its borders, and to prevent people from crossing its borders in violation of those laws.

The European Free Trade Association (EFTA) is a regional trade organisation and free trade area consisting of four European states: Iceland, Liechtenstein, Norway and Switzerland. The organisation operates in parallel with the European Union (EU), and all four member states participate in the European single market and are part of the Schengen Area. They are not, however, party to the European Union Customs Union.

EFTA was historically one of the two dominant western European trade blocs, but is now much smaller and closely associated with its historical competitor, the European Union. It was established on 3 May 1960 to serve as an alternative trade bloc for those European states that were unable or unwilling to join the then European Economic Community (EEC), the main predecessor of the EU. The Stockholm Convention (1960), to establish the EFTA, was signed on 4 January 1960 in the Swedish capital by seven countries (known as the "Outer Seven": Austria, Denmark, Norway, Portugal, Sweden, Switzerland and the United Kingdom). A revised Convention, the Vaduz Convention, was signed on 21 June 2001 and entered into force on 1 June 2002.

An economic and monetary union (EMU) is a type of trade bloc that features a combination of a common market, customs union, and monetary union. Established via a trade pact, an EMU constitutes the sixth of seven stages in the process of economic integration. An EMU agreement usually combines a customs union with a common market. A typical EMU establishes free trade and a common external tariff throughout its jurisdiction. It is also designed to protect freedom in the movement of goods, services, and people. This arrangement is distinct from a monetary union (e.g., the Latin Monetary Union), which does not usually involve a common market. As with the economic and monetary union established among the 27 member states of the European Union (EU), an EMU may affect different parts of its jurisdiction in different ways. Some areas are subject to separate customs regulations from other areas subject to the EMU. These various arrangements may be established in a formal agreement, or they may exist on a de facto basis. For example, not all EU member states use the Euro established by its currency union, and not all EU member states are part of the Schengen Area. Some EU members participate in both unions, and some in neither.

Territories of the United States, Australian External Territories and New Zealand territories each share a currency and, for the most part, the market of their respective mainland states. However, they are generally not part of the same customs territories.

Liechtenstein (/ˈlɪktənstaɪn/ , LIK-tən-styne; pronounced [ˈlɪçtn̩ʃtaɪn] ; Alemannic German: Liachtaschta), officially the Principality of Liechtenstein (German: Fürstentum Liechtenstein [ˈfʏʁstn̩tuːm ˈlɪçtn̩ʃtaɪn] ), is a doubly landlocked country in the Central European Alps. It is located between Austria to the east and north-east and Switzerland to the north-west, west and south. Formed in 1719, Liechtenstein became fully independent upon the dissolution of the German Confederation in 1866. Liechtenstein is a monarchy headed by the prince of Liechtenstein. Hans-Adam II, Prince of Liechtenstein has reigned over Liechtenstein since 1989. Liechtenstein is Europe's fourth-smallest country, with an area of just over 160 square kilometres (62 square miles) and a population of 41,389. It is the world's smallest country to border two countries, and is one of the few countries with no debt. Its official language is German.

Liechtenstein is divided into 11 municipalities. Its capital is Vaduz, and its largest municipality is Schaan. It is a member of the United Nations, the European Free Trade Association, and the Council of Europe. It is not a member state of the European Union, but it participates in both the Schengen Area and the European Economic Area. It has a customs union and a monetary union with Switzerland, with its usage of the Swiss franc. A constitutional referendum in 2003 granted the monarch greater powers, including the power to dismiss the government, nominate judges and veto legislation.

Llívia (Catalan pronunciation: [ˈʎiβiə]; Spanish: Llivia Spanish: [ˈʎiβja] ) is a town in the comarca of Cerdanya, province of Girona, Catalonia, Spain. It is a Spanish exclave surrounded by the French département of Pyrénées-Orientales. It is named after Livia, the wife of Augustus and matriarch of the Julio-Claudian dynasty. Because of a technicality in the Treaty of the Pyrenees, signed in 1659, that transferred only "villages" in the Pyrenees to France, Llívia, which was a "town", remains under Spanish control. The Segre river, a tributary of the Spanish Ebro, flows through Llívia. It has a population of 1,560 (register office, 2024) .

Llívia is separated from the rest of Spain by a corridor approximately 1.6 km (1.0 mile) wide, which includes the French communes of Ur and Bourg-Madame. This corridor is traversed by a road, owned by both France (where it is part of Route nationale 20 and RD68) and Spain (where it is part of N-154). Before the implementation of the Schengen Area in 1995, it was considered a "neutral road", a custom-free route with access for both French and Spanish people; since 1995, there have been no formal borders. The two countries share a hospital in Puigcerdà (which lies close to Llívia), as well as other local initiatives.

Border control comprises measures taken by governments to monitor and regulate the movement of people, animals, and goods across land, air, and maritime borders. While border control is typically associated with international borders, it also encompasses controls imposed on internal borders within a single state.

Border control measures serve a variety of purposes, ranging from enforcing customs, sanitary and phytosanitary, or biosecurity regulations to restricting migration. While some borders (including most states' internal borders and international borders within the Schengen Area) are open and completely unguarded, others (including the vast majority of borders between countries as well as some internal borders) are subject to some degree of control and may be crossed legally only at designated checkpoints. Border controls in the 21st century are tightly intertwined with intricate systems of travel documents, visas, and increasingly complex policies that vary between countries.

Saint Pierre and Miquelon (/ˈmiːkəlɒn/, MEEK-ə-lon), officially the Territorial Collectivity of Saint Pierre and Miquelon (French: Collectivité territoriale de Saint-Pierre-et-Miquelon), is a self-governing territorial overseas collectivity of France in the northwestern Atlantic Ocean, located near the Canadian province of Newfoundland and Labrador. St. Pierre and Miquelon is an archipelago of eight islands, covering 242 km (93 sq mi) of land. It had a population of 5,819 as of the January 2022 census and its residents are French citizens; they elect their own deputy to the National Assembly and participate in senatorial and presidential elections.

Saint Pierre and Miquelon is an Overseas Country and Territory (OCT) of the European Union, although not an integral part of it. It is neither part of the Schengen area, nor of the European customs territory. On the other hand, Saint Pierre and Miquelon is part of the Eurozone, and its inhabitants have European Union citizenship. The territory is also part of the Regional Joint Cooperation Commission (Atlantic Canada Cooperation), the Halifax Search and Rescue Region and the Northwest Atlantic Fisheries Organization.
