Enclave and exclave

Territory surrounded by another state


Territory surrounded by another state

  • A:
  • possesses 4 exclaves (A2, A3, A4, and A5) and one semi-exclave (A1): it is impossible to go from the main part of A to any of these parts going only through territory of A; however:
    • A1 and A2 are not enclaves: neither of them is surrounded by a single "foreign" territory;
    • A1 is only a semi-enclave and a semi-exclave, not an enclave or exclave: it has an unsurrounded sea border;
    • A2 is an exclave of A: it is separated from A;
    • A3 is an enclave: it is completely surrounded by B;
    • A4 and A5 are counter-enclaves (also known as second-order enclaves): territories belonging to A that are encroached inside the enclave E;
  • contains 1 enclave (E): "foreign" territory totally surrounded by territory of A;
  • contains 1 counter-counter-enclave, or third-order enclave (E1).
  • B:
  • contains 2 enclaves (A3 and D).
  • C:
  • continuous territory, contains no enclave or exclave
  • D:
  • is an enclaved territory: it is territorially continuous, but its territory is totally surrounded by a single "foreign" territory (B).
  • E:
  • is an enclaved territory: it is inside A;
  • contains 2 enclaves (A4 and A5), which are counter-enclaves of A;
  • possesses 1 counter-enclave (E1), which is a counter-counter-enclave as viewed by A and contained within A5.

In topological terms, A and E are each (sets of) unconnected surfaces, and B, C and D are connected surfaces. However, C and D are also simply connected surfaces, while B is not (it has first Betti number 2, the number of "holes" in B).

An enclave is a territory that is entirely surrounded by the territory of only one other state or entity. An enclave can be an independent territory or part of a larger one. Enclaves may also exist within territorial waters. Enclave is sometimes used improperly to denote a territory that is only partly surrounded by another state. Enclaves that are not part of a larger territory are not exclaves, for example Lesotho (enclaved by South Africa), San Marino and Vatican City (both enclaved by Italy) are enclaved sovereign states.

An exclave is a portion of a state or district geographically separated from the main part, by some surrounding alien territory. Many exclaves are also enclaves, but an exclave surrounded by the territory of more than one state is not an enclave. The Azerbaijani exclave of Nakhchivan is an example of an exclave that is not an enclave, as it borders Armenia, Iran, and Turkey.

Semi-enclaves and semi-exclaves are areas that, except for possessing an unsurrounded sea border, would otherwise be enclaves or exclaves. Semi-enclaves and enclaves are mutually exclusive. Likewise, semi-exclaves and exclaves are mutually exclusive. Enclaves and semi-enclaves can exist as independent states (Monaco, The Gambia and Brunei are semi-enclaves), while exclaves and semi-exclaves proper always constitute just a part of a sovereign state (like the Kaliningrad Oblast and the state of Alaska).

A pene-exclave is a part of the territory of one country that can be conveniently approachedby traffic in particularonly through the territory of another country. Pene-exclaves are also called functional exclaves or practical exclaves. Many pene-exclaves partially border their own territorial waters (i.e., they are not surrounded by other nations' territorial waters), such as Point Roberts, Washington, and Minnesota's Northwest Angle. A pene-exclave can also exist entirely on land, such as when intervening mountains render a territory inaccessible from other parts of a country except through alien territory. A commonly cited example is the Kleinwalsertal, a valley part of Vorarlberg, Austria, that is accessible only from Germany to the north.

Origin and usage

The word enclave is French and first appeared in the mid-15th century as a derivative of the verb enclaver (1283), from the colloquial Latin inclavare (to close with a key). Originally, it was a term of property law that denoted a land or parcel of land surrounded by land owned by a different owner, and that could not be reached for its exploitation in a practical and sufficient manner without crossing the surrounding land. In law, this created a servitude of passage for the benefit of the owner of the surrounded land. The first diplomatic document to contain the word enclave was the Treaty of Madrid, signed in 1526.

Later, the term enclave began to be used also to refer to parcels of countries, counties, fiefs, communes, towns, parishes, etc. that were surrounded by alien territory. This French word eventually entered English and other languages to denote the same concept, although local terms have continued to be used. In India, the word pocket is often used as a synonym for enclave (such as "the pockets of Puducherry district"). In British administrative history, subnational enclaves were usually called detachments or detached parts, and national enclaves as detached districts or detached dominions. In British ecclesiastic history, subnational enclaves were known as peculiars (see also royal peculiar).

The word exclave is a logically extended back-formation of enclave.

Characteristics

Enclaves exist for a variety of historical, political and geographical reasons. For example, in the feudal system in Europe, the ownership of feudal domains was often transferred or partitioned, either through purchase and sale or through inheritance, and often such domains were or came to be surrounded by other domains. In particular, this state of affairs persisted into the 19th century in the Holy Roman Empire, and these domains (principalities, etc.) exhibited many of the characteristics of sovereign states. Prior to 1866 Prussia alone consisted of more than 270 discontiguous pieces of territory.

Residing in an enclave within another country has often involved difficulties in such areas as passage rights, importing goods, currency, provision of utilities and health services, and host nation cooperation. Thus, over time, enclaves have tended to be eliminated. For example, two-thirds of the then-existing national-level enclaves were extinguished on 1 August 2015, when the governments of India and Bangladesh implemented a Land Boundary Agreement that exchanged 162 first-order enclaves (111 Indian and 51 Bangladeshi). This exchange thus effectively removed another two dozen second-order enclaves and one third-order enclave, eliminating 197 of the India–Bangladesh enclaves in all. The residents in these enclaves had complained of being effectively stateless. Only Bangladesh's Dahagram–Angarpota enclave remained.

Netherlands and Belgium decided to keep the enclave and exclave system in Baarle. As both Netherlands and Belgium are members of the European Union and Schengen Area, people, goods and services flow freely with few or no restrictions.

Enclave versus exclave

For illustration, in the figure (above), A1 is a semi-enclave (attached to C and also bounded by water that only touches C's territorial water). Although A2 is an exclave of A, it cannot be classed as an enclave because it shares borders with B and C. The territory A3 is both an exclave of A and an enclave from the viewpoint of B. The singular territory D, although an enclave, is not an exclave.

True enclaves

An enclave is a part of the territory of a state that is enclosed within the territory of another state. To distinguish the parts of a state entirely enclosed in a single other state, they are called true enclaves. A true enclave cannot be reached without passing through the territory of a single other state that surrounds it. In 2007, Evgeny Vinokurov called this the restrictive definition of "enclave" given by international law, which thus "comprises only so-called 'true enclaves'." Two examples are Büsingen am Hochrhein, a true enclave of Germany, and Campione d'Italia, a true enclave of Italy, both of which are surrounded by Switzerland.

The definition of a territory comprises both land territory and territorial waters. In the case of enclaves in territorial waters, they are called maritime (those surrounded by territorial sea) or lacustrine (if in a lake) enclaves. Most of the true national-level enclaves now existing are in Asia and Europe. While subnational enclaves are numerous the world over, there are only a few national-level true enclaves in Africa, Australia and the Americas (each such enclave being surrounded by the territorial waters of another country).

A historical example is West Berlin before the reunification of Germany. Since 1945, all of Berlin had been ruled de jure by the four Allied powers. However, the East German government and the Soviet Union treated East Berlin as an integral part of East Germany, so West Berlin was a de facto enclave within East Germany. Also, 12 small West Berlin enclaves, such as Steinstücken, were separated from the city, some by only a few meters.

True exclaves

True exclave is an extension of the concept of true enclave. In order to access a true exclave from the mainland, a traveller must go through the territory of at least one other state. The Nakhchivan Autonomous Republic is an example of a true exclave, as a traveller must go through the territory of Armenia to access Nakhchivan from the Azerbaijan mainland.
