Demilitarized zone in the context of "North Korea"

The causes of World War II have been given considerable attention by historians. The immediate precipitating event was the invasion of Poland by Nazi Germany on September 1, 1939, and the subsequent declarations of war on Germany made by Britain and France, but many other prior events have been suggested as ultimate causes. Primary themes in historical analysis of the war's origins include the political takeover of Germany in 1933 by Adolf Hitler and the Nazi Party; Japanese militarism against China, which led to the Japanese invasion of Manchuria and the Second Sino-Japanese War; Italian aggression against Ethiopia, which led to the Second Italo-Ethiopian War; or military uprising in Spain, which led to the Spanish Civil War.

During the interwar period, deep anger arose in the Weimar Republic over the conditions of the 1919 Treaty of Versailles, which punished Germany for its role in World War I with heavy financial reparations and severe limitations on its military that were intended to prevent it from becoming a military power again. The demilitarisation of the Rhineland, the prohibition of German unification with Austria, and the loss of its overseas colonies as well as some 12% of the pre-war land area and population of the metropole all provoked strong currents of revanchism in German politics.

Nicosia, also known as Lefkosia or Lefkoşa, is the capital of Cyprus and the de jure capital of Northern Cyprus, which is geographically located in Asia. It is the southeasternmost capital city among European Union member states.

Nicosia has been continuously inhabited for over 5,500 years and has been the capital of Cyprus since the 10th century. It is the last divided capital in Europe; three years after Cyprus gained independence from British rule in 1960, the Bloody Christmas conflict between Greek Cypriots and Turkish Cypriots triggered island-wide intercommunal violence, and Nicosia's Greek Cypriot and Turkish Cypriot communities segregated into its south and north respectively in 1964. A decade later, Turkey invaded Cyprus following Greece's successful attempt to take over the island. The leaders of the takeover would later step down, but the dividing line running through Nicosia (and the rest of the island, interrupted only briefly by British military bases) became a demilitarised zone that remains under the control of Cyprus while heavily policed by the United Nations; it is now known as the United Nations Buffer Zone in Cyprus between the Republic of Cyprus, which is internationally recognised, and Northern Cyprus, which is recognised only by Turkey. The ongoing dispute between the two communities is known as the Cyprus problem.

The United Nations Buffer Zone in Cyprus is a demilitarized zone, patrolled by the United Nations Peacekeeping Force in Cyprus (UNFICYP), that was established on 4 March 1964. It was extended on 9 August after the Battle of Tillyria and extended again in 1974 after the ceasefire of 16 August 1974, following the Turkish invasion of Cyprus and the de facto partition of the island into the area controlled by the Republic of Cyprus (excluding the British Sovereign Base Areas) and the largely unrecognized Turkish Republic of Northern Cyprus in the north. The zone, also known as the Green Line (Greek: Πράσινη Γραμμή, Prasini Grammi; Turkish: Yeşil Hat), stretches for 180 kilometres (112 miles) from Paralimni in the east to Kato Pyrgos in the west, where a separate section surrounds Kokkina.

The dividing line is also referred to as the Attila Line, named after Turkey's 1974 military invasion, codenamed Operation Attila. The Turkish army has built a barrier on the zone's northern side, consisting mainly of barbed-wire fencing, concrete wall segments, watchtowers, anti-tank ditches, and minefields. The zone cuts through the centre of Nicosia, separating the city into southern and northern sections. In total, it spans an area of 346 square kilometres (134 sq mi), varying in width from less than 20 metres (66 ft) to more than 7 kilometres (4.3 mi). After the fall of the Berlin Wall in 1989, Nicosia remains the last divided capital in Europe. Some 10,000 people live in several villages and work on farms located within the zone; the village of Pyla is famous for being one of the few remaining villages in Cyprus where Greek and Turkish Cypriots still live side by side. Other villages are Deneia, Athienou, and Troulloi. Some areas are untouched by human interference and have remained a safe haven for flora and fauna.

A buffer state is a country geographically lying between two rival or potentially hostile great powers. Its existence can sometimes be thought to prevent conflict between them. A buffer state is sometimes a mutually agreed upon area lying between two greater powers, which is demilitarised in the sense of not hosting the armed forces of either power (though it will usually have its own military forces). The invasion of a buffer state by one of the powers surrounding it will often result in war between the powers.

Buffer states, when authentically independent, typically pursue a neutralist foreign policy, which distinguishes them from satellite states. The concept of buffer states is part of a theory of the balance of power that entered European strategic and diplomatic thinking in the 18th century. After the First World War, notable examples of buffer states were Poland and Czechoslovakia, situated between major powers such as Germany and the Soviet Union. Lebanon is another significant example, positioned between Syria and Israel, thereby experiencing challenges as a result.

Åland (/ˈɔːlənd/ AW-lənd, Swedish: [ˈǒːland] ; Finnish: Ahvenanmaa) is an autonomous and demilitarised region of Finland. Receiving its autonomy by a 1920 decision of the League of Nations, it is the smallest region of Finland by both area (1,580 km or 610 sq mi) and population (30,654), constituting 0.51% of Finland's land area and 0.54% of its population. Its official language is Swedish and the capital city is Mariehamn.

Åland is situated in an archipelago, called the Åland Islands, at the entrance to the Gulf of Bothnia in the Baltic Sea. It comprises Fasta Åland, on which 90% of the population resides, and about 6,500 skerries and islands to its east, of which about 60–80 are inhabited. Fasta Åland is separated from the coast of Roslagen in Sweden by 38 km (20+1⁄2 nautical miles) of open water to the west. In the east, the Åland archipelago is contiguous with the Finnish archipelago. Åland's only land border is located on the uninhabited skerry of Märket, which it shares with Sweden. From Mariehamn, there is a ferry distance of about 160 km (86 nautical miles) to Turku, a coastal city of mainland Finland, and also to Stockholm, the capital of Sweden.

The Korean Demilitarized Zone (Korean: 한반도/조선반도 비무장 지대) is a heavily militarized strip of land running across the Korean Peninsula near the 38th parallel north. The demilitarized zone (DMZ) is a border barrier that divides the peninsula roughly in half. It was established to serve as a buffer zone between the sovereign states of the Democratic People's Republic of Korea (North Korea) and the Republic of Korea (South Korea) under the provisions of the Korean Armistice Agreement in 1953, an agreement between North Korea, China, and the United Nations Command.

The DMZ is 250 kilometers (160 mi) long and about 4 kilometers (2.5 mi) wide. There have been various incidents in and around the DMZ, with military and civilian casualties on both sides. Within the DMZ is a meeting point between the two Korean states, where negotiations take place: the small Joint Security Area (JSA) near the western end of the zone.

A buffer zone, also historically known as a march, is a neutral area that lies between two or more bodies of land; usually, between countries. Depending on the type of buffer zone, it may serve to separate regions or conjoin them.Common types of buffer zones are demilitarized zones, border zones and certain restrictive easement zones and green belts. Such zones may be comprised by a sovereign state, forming a buffer state.

Buffer zones have various purposes, politically or otherwise. They can be set up for a multitude of reasons, such as to prevent violence, protect the environment, shield residential and commercial zones from industrial accidents or natural disasters, or even isolate prisons. Buffer zones often result in large uninhabited regions that are themselves noteworthy in many increasingly developed or crowded parts of the world that unintentionally create a de facto wildlife sanctuary.

The Svalbard Act of 17 July 1925 no. 11, normally referred to as the Svalbard Act (Norwegian: lov om Svalbard or colloquially Svalbardloven), is a law of Norway which governs the major aspects of the Svalbard archipelago. The law was passed by the Parliament of Norway on 17 July 1925, establishes Norwegian sovereignty of the island, and states that Norwegian criminal law, civil law and procedure law are enforced on the island. Otherwise, other provisions and laws only apply when specified. The act further established the policy for administration, including creating the Governor of Svalbard, and since 2002, Longyearbyen Community Council. The act also establishes rules for real estate and environmental protection.

The act was passed as a response to the Spitsbergen Treaty of 9 February 1920, which established Norwegian sovereignty of Svalbard, but limited the archipelago to a free economic zone and demilitarized zone. The act established the basis for an orderly civil society on the islands, which had until that point been prone to lawlessness among miners, fishermen and hunters.
