Some borders—such as most states' internal administrative borders, or inter-state borders within the Schengen Area—are open and completely unguarded.[2] 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.
Buffer zones may be set up on borders between belligerent entities to lower the risk of escalation. While border refers to the boundary itself, the area around the border is called the frontier.
Overview
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.
Some borders require presentation of legal paperwork like passports and visas, or other identity documents, for persons to cross borders. To stay or work within a country's borders aliens (foreign persons) may need special immigration documents or permits; but possession of such documents does not guarantee that the person should be allowed to cross the border.
Moving goods across a border often requires the payment of excise tax, often collected by customs officials. Animals (and occasionally humans) moving across borders may need to go into quarantine to prevent the spread of exotic infectious diseases. Most countries prohibit carrying illegal drugs or endangered animals across their borders. Moving goods, animals, or people illegally across a border, without declaring them or seeking permission, or deliberately evading official inspection, constitutes smuggling. Controls on car liability insurance validity and other formalities may also take place.

In places where smuggling, migration, and infiltration are a problem, many countries fortify borders with fences and barriers, and institute formal border control procedures. These can extend inland, as in the United States where the U.S. Customs and Border Protection service has jurisdiction to operate up to 100 miles from any land or sea boundary.[3] On the other hand, some borders are merely signposted. This is common in countries within the European Schengen Area and on rural sections of the Canada–United States border. Borders may even be completely unmarked, typically in remote or forested regions; such borders are often described as "porous". Migration within territorial borders, and outside of them, represented an old and established pattern of movement in African countries, in seeking work and food, and to maintain ties with kin who had moved across the previously porous borders of their homelands. When the colonial frontiers were drawn, Western countries attempted to obtain a monopoly on the recruitment of labor in many African countries, which altered the practical and institutional context in which the old migration patterns had been followed, and some might argue, are still followed today. The frontiers were particularly porous for the physical movement of migrants, and people living in borderlands easily maintained transnational cultural and social networks.
A border may have been:
Agreed by the countries on both sides
Imposed by the country on one side
Imposed by third parties, e.g. an international conference
Inherited from a former state, colonial power or aristocratic territory
Inherited from a former internal border, such as within the former Soviet Union
Never formally defined.
In addition, a border may be a de facto military ceasefire line.
History
In the pre-modern world, the term border was vague and could refer to either side of the boundary, thus it was necessary to specify part of it with borderline or borderland. During the medieval period the government's control frequently diminished the further people got from the capital. Therefore borderland (especially impassable terrain) attracted many outlaws, as they often found sympathizers.[4]
In the past, many borders were not clearly defined lines; instead there were often intervening areas often claimed and fought over by both sides, sometimes called marchlands. Special cases in modern times were the Saudi Arabian–Iraqi neutral zone from 1922 to 1991 and the Saudi Arabian–Kuwaiti neutral zone from 1922 until 1970. In modern times, marchlands have been replaced by clearly defined and demarcated borders.
Political borders are imposed on the world through human agency.[5] That means that although a political border may follow a river or mountain range, such a feature does not automatically define the political border, even though it may be a major physical barrier to crossing.
Political borders are often classified by whether or not they follow conspicuous physical features on the earth. William Miles said that Britain and France traced close to 40% of the entire length of the world's international boundaries.[6]
Natural borders

Natural borders are geographical features that present natural obstacles to communication and transport. Existing political borders are often a formalization of such historical, natural obstacles.
Some geographical features that often constitute natural borders are:
Oceans: oceans create very costly natural borders. Very few countries span more than one continent. Only very large and resource-rich states are able to sustain the costs of governance across oceans for longer periods of time.
Throughout history, technological advances have reduced the costs of transport and communication across the natural borders. That has reduced the significance of natural borders over time. As a result, political borders that have been formalized more recently, such as those in Africa or Americas, typically conform less to natural borders[citation needed] than very old borders, such as those in Europe or Asia, do.
Landscape borders
A landscape border is a mixture of political and natural borders. One example is the defensive forest created by China's Song dynasty in the eleventh century.[7] Such a border is political in the sense that it is human-demarcated, usually through a treaty. However, a landscape border is not demarcated by fences and walls but instead landscape features such as forests, mountains, and water bodies. It is different from a natural border, however, in the sense that the border landscape is not natural but human-engineered. Such a landscape usually differs from the borderland's natural geography and its building requires tremendous human labour and financial investment.
Geometric borders
Geometric boundaries[citation needed] are formed by straight lines (such as lines of latitude or longitude), or occasionally arcs (Pennsylvania/Delaware), regardless of the physical and cultural features of the area. Such political boundaries are often found around the states that developed out of colonial holdings, such as in North America,[8]Africa[citation needed] and the Middle East. The Canada–United States border follows the 49th parallel for roughly 2,175 miles (3,500km) from Lake of the Woods (Ontario and Minnesota) west to the Pacific Ocean.
Fiat borders
A generalization of the idea of geometric borders is the idea of fiat boundaries by which is meant any sort of boundary that does not track an underlying bona fide physical discontinuity (fiat, Latin for "let it be done", a decision). Fiat boundaries are typically the product of human demarcation, such as in demarcating electoral districts or postal districts.[9]
Relic borders
The purpose of the Great Wall of China was to stop people and militaries from crossing the northern border of China. Today it is a relic border.
A relic border is a former boundary, which may no longer be a legal boundary at all. However, the former presence of the boundary can still be seen in the landscape. For instance, the boundary between East and West Germany is no longer an international boundary, but it can still be seen because of historical markers on the landscape; it remains a cultural and economic demarcation in Germany. Other examples include the Demilitarized Zone between North and South Vietnam (defunct since 1975) and the border between North and South Yemen (defunct since 1990). Occasionally a relic border is reconstituted in some form, for example the border between British Somaliland and Italian Somaliland ceased to exist when the two colonies merged to form the independent state of Somalia in 1960, however when the former British Somaliland declared independence in 1991 it claimed the former British-Italian line as its eastern border.[10]
Lines of control
A line of control (LoC) refers to a militarized buffer border between two or more nations that has yet to achieve permanent border status. LoC borders are typically under military control and are not recognized as an official international border. Formally known as a cease-fire line, an LoC was first created with the Simla Agreement between India and Pakistan.[11] Similar to a cease-fire line, an LoC is typically the result of war, military stalemates and unresolved land ownership conflict.[12]
A maritime border is a division enclosing an area in the ocean where a nation has exclusive rights over the mineral and biological resources,[13] encompassing maritime features, limits and zones.[14] Maritime borders represent the jurisdictional borders of a maritime nation[15] and are recognized by the United Nations Convention on the Law of the Sea.
Some maritime borders have remained indeterminate despite efforts to clarify them. This is explained by an array of factors, some of which illustrate regional problems.[16]
Airspace borders
Airspace is the atmosphere located within a country's controlled international and maritime borders. All sovereign countries hold the right to regulate and protect air space under the international law of Air sovereignty.[17] The horizontal boundaries of airspace are similar to the policies of "high seas" in maritime law. Airspace extends 12 nautical miles from the coast of a country and it holds responsibility for protecting its own airspace unless under NATO peacetime protection.[17][18] With international agreement a country can assume the responsibility of protecting or controlling the atmosphere over International Airspaces such as the Pacific Ocean. The vertical boundaries of airspace are not officially set or regulated internationally. However, there is a general agreement of vertical airspace ending at the point of the Kármán line.[19] The Kármán line is a peak point at the altitude of 62mi (100km) above the Earth's surface, setting a boundary between the atmosphere (airspace) and outer space (which is governed by space law).[20]
The frontier is a border that is open-ended to one side, identifying an expanding borderland to one side.
This type of border can be fairly abstract and has been identified as a particular state of mind[21] for human activity. As such frontiers have been applied to borderlands identifying and claiming them as terra nullius, such as Marie Byrd Land in West Antarctica, the only territory in Antarctica unclaimed by any sovereign nation.[22]
Regulated borders have varying degrees of control on the movement of persons and trade between nations and jurisdictions. Most industrialized nations have regulations on entry and require one or more of the following procedures: visa check, passport check or customs checks.[23] Most regulated borders have regulations on immigration, types of wildlife and plants, and illegal objects such as drugs or weapons. Overall border regulations are placed by national and local governments and can vary depending on nation and current political or economic conditions. Some of the most regulated borders in the world include: Australia, the United States, Israel, Canada, the United Kingdom, and the United Arab Emirates.[24] These nations have government-controlled border agencies and organizations that enforce border regulation policies on and within their borders.
Open borders

An open border is the deregulation and or lack of regulation on the movement of persons between nations and jurisdictions. This definition does not apply to trade or movement between privately owned land areas.[25] Most nations have open borders for travel within their nation of travel, though more authoritarian states may limit the freedom of internal movement of its citizens, as for example in the former USSR. However, only a handful of nations have deregulated open borders with other nations, an example of this being European countries under the Schengen Agreement or the open Belarus-Russia border.[26] Open borders used to be very common amongst all nations, however this became less common after the First World War, which led to the regulation of open borders, making them less common and no longer feasible for most industrialized nations.[27] An example of Open orders include the Schengen Area where 29 European nations mutually abolished their border control.[28]
A demilitarized zone (DMZ) is a border separating two or more nations, groups or militaries that have agreed to prohibit the use of military activity or force within the border's bounds. A DMZ can act as a war boundary, ceasefire line, wildlife preserve, or a de facto international border. An example of a demilitarized international border is the 38th parallel between North and South Korea.[29] Other notable DMZ zones include Antarctica and outer space (consisting of all space 100 miles away from the earth's surface), both are preserved for world research and exploration.[30][31] The prohibition of control by nations can make a DMZ unexposed to human influence and thus developed into a natural border or wildlife preserve, such as on the Korean Demilitarized Zone, the Vietnamese Demilitarized Zone, and the Green Line in Cyprus.[32][33]

Borders undermine economic activity and development by reducing trade activity.[34][35][36]
The presence of borders often fosters certain economic features or anomalies. Wherever two jurisdictions come into contact, special economic opportunities arise for border trade. Smuggling provides a classic case; contrariwise, a border region may flourish on the provision of excise or of import–export services — legal or quasi-legal, corrupt or legitimate. Different regulations on either side of a border may encourage services to position themselves at or near that border: thus the provision of pornography, of prostitution, of alcohol, fireworks, and/or of narcotics may cluster around borders, city limits, county lines, ports and airports. In a more planned and official context, Special Economic Zones (SEZs) often tend to cluster near borders or ports.
Even if the goods are not perceived to be undesirable, states will still seek to document and regulate the cross-border trade in order to collect tariffs and benefit from foreign currency exchange revenues.[37] Thus, there is the concept unofficial trade in goods otherwise legal; for example, the cross-border trade in livestock by pastoralists in the Horn of Africa. Ethiopia sells an estimated $250 to $300 million of livestock to Somalia, Kenya and Djibouti every year unofficially, over 100 times the official estimate.[37]
Human economic traffic across borders (apart from kidnapping) may involve mass commuting between workplaces and residential settlements. The removal of internal barriers to commerce, as in France after the French Revolution or in Europe since the 1940s, de-emphasizes border-based economic activity and fosters free trade. Euroregions are similar official structures built around commuting across boundary.

Political borders have a variety of meanings for those whom they affect. Many borders in the world have checkpoints where border control agents inspect persons and/or goods crossing the boundary.
In much of Europe, controls on persons were abolished by the 1985 Schengen Agreement and subsequent European Union legislation. Since the Treaty of Amsterdam, the competence to pass laws on crossing internal and external borders within the European Union and the associated Schengen Area states (Iceland, Norway, Switzerland, and Liechtenstein) lies exclusively within the jurisdiction of the European Union, except where states have used a specific right to opt out (United Kingdom and Ireland, which maintain the Common Travel Area amongst themselves).
Historic borders such as the Great Wall of China, the Maginot Line, and Hadrian's Wall have played a great many roles and been marked in different ways. While the stone walls, the Great Wall of China and the Roman Hadrian's Wall in Britain had military functions, the entirety of the Roman borders were very porous, which encouraged Roman economic activity with neighbors.[38] On the other hand, a border like the Maginot Line was entirely military and was meant to prevent any access in what was to be World War II to France by its neighbor, Germany; Germany ended up going around the Maginot Line through Belgium just as it had done in World War I.

Borders have sometimes been significantly shaped by physical border constructions and openings. From border crossings, over border markers to border barriers these constructions fulfill many different functions. Such as also providing crossover.
Even the most fortified borders reserve specific places to allow crossing. The many forms of borders have different ways of enabling and controlling passage.
Borders can have a significant impact on and function for movement. It can enable and stop movement, across as well as along borders.
The permeability of borders depends on its construction, availability of crossings, regulation and types or scope of activity. The permeability can vary, borders can be barriers for humans, but also for animal migration or types of pollution.
Macro-regional integration initiatives, such as the European Union and NAFTA, have spurred the establishment of cross-border regions. These are initiatives driven by local or regional authorities, aimed at dealing with local border-transcending problems such as transport and environmental degradation.[39] Many cross-border regions are also active in encouraging intercultural communication and dialogue as well as cross-border economic development strategies. In Europe, the European Union provides financial support to cross-border regions via its Interreg programme. The Council of Europe has issued the Outline Convention on Transfrontier Co-operation, providing a legal framework for cross-border co-operation even though it is in practice rarely used by Euroregions.
Border art is a contemporary art practice rooted in the socio-political experience(s), such as of those on the U.S.-Mexico borderlands, or frontera. Since its conception in the mid-80's, this artistic practice has assisted in the development of questions surrounding homeland, borders, surveillance, identity, race, ethnicity, and national origin(s).
Border art as a conceptual artistic practice, however, opens up the possibility for artists to explore similar concerns of identity and national origin(s) but whose location is not specific to the U.S-Mexico border. A border can be a division, dividing groups of people and families. Borders can include but are not limited to language, culture, social and economic class, religion, and national identity. In addition to a division, a border can also conceive a borderland area that can create a cohesive community separate from the mainstream cultures and identities portrayed in the communities away from the borders, such as the Tijuana-San Diego border between Mexico and the United States.
Border art can be defined as an art that is created in reference to any number of physical or imagined boundaries. This art can but is not limited to social, political, physical, emotional and/or nationalist issues. Border art is not confined to one particular medium. Border art/artists often address the forced politicization of human bodies and physical land and the arbitrary, yet incredibly harmful, separations that are created by these borders and boundaries. These artists are often "border crossers" themselves. They may cross borders of traditional art-making (through performance, video, or a combination of mediums). They may at once be artists and activists, existing in multiple social roles at once. Many border artists defy easy classifications in their artistic practice and work.

A territorial dispute or boundary dispute is a disagreement over the possession or control of territories between two or more political entities.
A demilitarized zone is an area in which treaties or agreements between states, military powers or contending groups forbid military installations, activities, or personnel. A DZ often lies along an established frontier or boundary between two or more military powers or alliances. A DZ may sometimes form a de facto international border, such as the Korean Demilitarized Zone. Other examples of demilitarized zones are a 14 km (8.7 mi) wide area between Iraq and Kuwait; Antarctica ; and outer space.
The Schengen Agreement is a treaty which led to the creation of Europe's Schengen Area, in which internal border checks have largely been abolished. It was signed on 14 June 1985, near the town of Schengen, Luxembourg, by five of the ten member states of the then European Economic Community. It proposed measures intended to gradually abolish border checks at the signatories' common borders, including reduced-speed vehicle checks which allowed vehicles to cross borders without stopping, allowing residents in border areas freedom to cross borders away from fixed checkpoints, and the harmonisation of visa policies.
Transport in Europe provides for the movement needs of over 700 million people and associated freight.
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.
A border checkpoint is a location on an international border where travelers or goods are inspected and allowed passage through. Authorization often is required to enter a country through its borders. Access-controlled borders often have a limited number of checkpoints where they can be crossed without legal sanctions. Arrangements or treaties may be formed to allow or mandate less restrained crossings. Land border checkpoints can be contrasted with the customs and immigration facilities at seaports, international airports, and other ports of entry.
The Military Demarcation Line (MDL), sometimes referred to as the Armistice Line, is the land border or demarcation line between North Korea and South Korea. On either side of the line is the Korean Demilitarized Zone (DMZ). The MDL and DMZ were established by the Korean Armistice Agreement.
The Canada–United States border is the longest international border in the world. The boundary is 8,891 km (5,525 mi) long. The land border has two sections: Canada's border with the contiguous United States to its south, and with the U.S. state of Alaska to its west. The bi-national International Boundary Commission deals with matters relating to marking and maintaining the boundary, and the International Joint Commission deals with issues concerning boundary waters. The agencies responsible for facilitating legal passage through the international boundary are the Canada Border Services Agency (CBSA) and U.S. Customs and Border Protection (CBP).
An exclusive economic zone (EEZ), as prescribed by the 1982 United Nations Convention on the Law of the Sea, is an area of the sea in which a sovereign state has exclusive rights regarding the exploration and use of marine resources, including energy production from water and wind.
The Aegean dispute is a set of interrelated controversies between Greece and Turkey over sovereignty and related rights in the region of the Aegean Sea. This set of conflicts has strongly affected Greek-Turkish relations since the 1970s, and has twice led to crises coming close to the outbreak of military hostilities, in 1987 and in early 1996. The issues in the Aegean fall into several categories:
The Republic of Ireland–United Kingdom border, sometimes referred to as the Irish border or British–Irish border, runs for 499 km (310 mi) from Lough Foyle in the north-west of Ireland to Carlingford Lough in the north-east, separating the Republic of Ireland from Northern Ireland.
The Mexico–United States border is an international border separating Mexico and the United States, extending from the Pacific Ocean in the west to the Gulf of Mexico in the east. The border traverses a variety of terrains, ranging from urban areas to deserts. It is the most frequently crossed border in the world with approximately 350 million documented crossings annually. Illegal crossing of the border to enter the United States has caused the Mexico–United States border crisis. It is one of two international borders that the United States has, the other being the northern Canada–United States border; Mexico has two other borders: with Belize and with Guatemala.
The Northern Limit Line or North Limit Line (NLL) – 북방한계선 – is a disputed maritime demarcation line in the Yellow (West) Sea between the Democratic People's Republic of Korea (DPRK) in the north, and the Republic of Korea (ROK) in the south. This line of military control acts as the de facto maritime boundary between North and South Korea.
Sir Creek, originally Ban Ganga, is a 96 km tidal estuary in the uninhabited marshlands of the Indus River Delta on the border between India and Pakistan. The creek flows into the Arabian Sea and separates Gujarat state in India from Sindh province in Pakistan. The long-standing India-Pakistan Sir Creek border dispute stems from the demarcation "from the mouth of Sir Creek to the top of Sir Creek, and from the top of Sir Creek eastward to a point on the line designated on the Western Terminus". From this point onward, the boundary is unambiguously fixed as defined by the Tribunal Award of 1968.
The Schengen Area is an area encompassing 29 European countries that have officially abolished border controls at their mutual borders. Being an element within the wider area of freedom, security and justice policy of the European Union (EU), it mostly functions as a single jurisdiction under a common visa policy for international travel purposes. The area is named after the 1985 Schengen Agreement and the 1990 Schengen Convention, both signed in Schengen, Luxembourg.
An open border is a border that enables free movement of people between jurisdictions with no restrictions on movement and is lacking substantive border control. A border may be an open border due to intentional legislation allowing free movement of people across the border, or a border may be an open border due to a lack of legal controls, a lack of adequate enforcement or adequate supervision of the border. An example of the former is the Schengen Agreement between most members of the European Economic Area. An example of the latter has been the border between Bangladesh and India, which is becoming controlled. The term "open borders" applies only to the flow of people, not the flow of goods and services, and only to borders between political jurisdictions, not to mere boundaries of privately owned property.
A maritime boundary is a conceptual division of Earth's water surface areas using physiographical or geopolitical criteria. As such, it usually bounds areas of exclusive national rights over mineral and biological resources, encompassing maritime features, limits and zones. Generally, a maritime boundary is delineated at a particular distance from a jurisdiction's coastline. Although in some countries the term maritime boundary represents borders of a maritime nation that are recognized by the United Nations Convention on the Law of the Sea, maritime borders usually serve to identify the edge of international waters.
The international border between Finland and Russia is 1,340 km (830 mi) long and runs approximately north to south, mostly through taiga forests and sparsely populated rural areas. It does not follow any natural landmarks, such as mountains or rivers. It is also an external border of the European Union and NATO.
The border of the European Union consists of the land borders that member states of the EU share with non-EU states adjacent to the union. The EU shares land borders with 21 countries and 3 dependencies.
Controls imposed on internal borders within a single state or territory include measures taken by governments to monitor and regulate the movement of people, animals, and goods across land, air, and maritime borders through border controls.

The World in 2015: National borders undermined? 11-min video interview with Bernard Guetta, a columnist for Libération newspaper and France Inter radio. "For [Guetta], one of the main lessons from international relations in 2014 is that national borders are becoming increasingly irrelevant. These borders, drawn by the colonial powers, were and still are entirely artificial. Now, people want borders along national, religious or ethnic lines. Bernard Guetta calls this a "comeback of real history"."
