Antarctica

Further information: Territorial claims of Antarctica

The Antarctic Treaty System, formed on 1 December 1959 and entered into force on 23 June 1961, establishes the legal framework for the management of Antarctica and provides administration for the continent, which is carried out through consultative member meetings. It freezes the territorial claims of all signatories (all claimants have acceded) for as long as the treaty is in force. However, it is not a final settlement; parties can choose to withdraw from the System at any time. Furthermore, only a minority of states have signed it, and it is not formally sanctioned by the United Nations. Thus, Antarctica remains the only part of the planet any (non-signatory) state can still lay claim to as terra nullius (on the grounds of it not having been part of any existing state's legal and effective territory).

Bay of Bengal Maritime Boundary between Bangladesh and India	India Bangladesh	1974	2014	India and Bangladesh had engaged in eight rounds of bilateral negotiations starting 1974 but it remained inconclusive till 2009. In October 2009, Bangladesh served India with notice of arbitration proceedings under the UNCLOS . The Arbitration Tribunal delivered the ruling on 7 July 2014 and settled the dispute.
Indo-Bangladesh enclaves, adverse possessions and undemarcated land boundaries	India Bangladesh	1947	2015	Following Partition of Bengal (1947), the issues of adverse possessions, enclaves and unmarked boundary arose. Inside the main part of Bangladesh, there were 111 Indian enclaves (17,160.63 acres), while inside the main part of India, there were 51 Bangladeshi enclaves (7,110.02 acres). In 1974 Bangladesh approved a proposed treaty, Land Boundary Agreement, to exchange all enclaves within each other's territories, but India did not ratified it. Another agreement was agreed upon in 2011 to exchange enclaves and adverse possessions. In respect of adverse possessions, India received 2,777.038 acres of land and transferred 2,267.682 acres to Bangladesh. India ratified the agreement by constitutional amendment in May 2015.
South Talpatti/New Moore/Purbasha Island	India Bangladesh	c. 1975	2010	This former dispute over a small island never more than two meters above sea level was contested from the island's appearance in the 1970s to its disappearance, likely due to climate change, in the first decade of the 2000s. Though land disputes no longer exist, the maritime boundary did not settled until 2014.
Sakhalin Island	Russian Empire Empire of Japan	1845	1875	Japan unilaterally proclaimed sovereignty over the whole island in 1845, but its claims were ignored by the Russian Empire. The 1855 Treaty of Shimoda acknowledged that both Russia and Japan had joint rights of occupation to Sakhalin, without setting a definite territorial demarcation. As the island became settled in the 1860s and 1870s, this ambiguity led to increasing friction between settlers. Attempts by the Tokugawa shogunate to purchase the entire island from the Russian Empire failed, and the new Meiji government was unable to negotiate a partition of the island into separate territories. In 1875 by the Treaty of Saint Petersburg, Japan agreed to give up its claims on Sakhalin in exchange for undisputed ownership of the Kuril Islands. In 1905 under the Treaty of Portsmouth Japan gained Sakhalin to the 60th parallel, but lost it again in 1945.

Although most of Sinai was returned to Egypt in 1982, Taba was the last portion to be returned. The issue was submitted to an international commission. In 1988, the commission ruled in Egypt's favour, and Israel returned Taba to Egypt in 1989.

Alaska Boundary Dispute	United States Canada	1821	1903	Disputed between the United States and Canada (then a British Dominion with its foreign affairs controlled from London). The dispute had been going on between the Russian and British Empires since 1821, and was inherited by the United States as a consequence of the Alaska Purchase in 1867. It was resolved by arbitration in 1903 with a delegation that included 3 Americans, 2 Canadians, and 1 British delegate that became the swing vote. By a 4 to 2 vote, the final resolution favored the American position. Canada did not get an outlet from the Yukon gold fields to the sea. The disappointment and anger in Canada was directed less at the United States, and more at the British government for betraying Canadian interests in pursuit of a friendly relationship between Britain and the United States.

Dispute over the borders between the three colonies dates to the foundation of each during the middle 17th century. A series of defined lines and arcs were laid out by statute to settle the disputes, the most famous of which was the Mason–Dixon line. The Wedge was left out of all three colonies (and later U.S. states), and remained a matter of dispute until it was formally resolved to assign the Wedge to Delaware in 1921.

Border of New Hampshire and Canada	United States United Kingdom	1783	1842	Ill-defined terms of the Treaty of Paris at the end of the Revolutionary War left the boundary of the state of New Hampshire and Canada in doubt. The lack of a precise definition of the "northwesternmost head of the Connecticut River" as defined by the Treaty of Paris left a tract of land in what is now the town of Pittsburg, New Hampshire outside of the jurisdiction of both the United States and Canada. In the 1830s, land speculators established a short-lived independent republic in the area; the minuscule population of the putative nation never exceeded about 300. The boundary was finally settled definitively by the Webster–Ashburton Treaty of 1842.

Åland Islands	Finland Sweden	1917	1920	Sweden and Finland argued over the control of the Åland Islands (located between Sweden and Finland). The Åland movement (Ålandsrörelsen) wanted Åland to reunite with its old mother country Sweden (Finland and Åland belonged to Sweden before 1809). The movement gathered signatures from over 7000 inhabitants of legal age at the Åland Islands in 1917 (that was about 96% of the population) - they all supported a union with Sweden. When Finland became independent (December 6, 1917) Sweden wanted a plebiscite about the future of the Åland Islands to solve the problem. Finland refused and argued that the Åland Islands had always been a natural part of Finland - even when Finland was under Swedish rule. Sweden appealed to the League of Nations referring to the right of the population to determine which country they should belong to. After studying the matter closely the League of Nations decided Finland should retain sovereignty over the province but that the Åland Islands should be made an autonomous territory. The Swedish Prime Minister said he didn’t accept the verdict but he also said that Sweden was not going to use military force to get their claims.
Graham Island	Two Sicilies Malta France Spain	1831	1831	A dispute between the Kingdom of the Two Sicilies, the British Crown Colony of Malta, the Kingdom of France and the Kingdom of Spain occurred after the volcanic island appeared in 1831. The British were the first to claim the island as part of Malta, and they were followed by the Two Sicilies and France, while Spain expressed their ambitions to control the island. The island disappeared by December 1831 and the dispute stopped. A Sicilian flag was lowered over the now submerged island in 2000 to show Italian claims to the area. It is no longer disputed by Britain, France, Spain or Malta.
Lampedusa	Sicily Malta	1800	1814	The island was controlled by British troops as a de facto part of Malta Protectorate from 1800 onwards.

The new Turkish Government of Mustafa Kemal Atatürk, based in Ankara, which was not party to the treaty, overthrew the Ottoman government, which signed but did not ratify the treaty. After the Turkish War of Independence ended in Greek defeat in Anatolia, and the fall of Lloyd George and his Middle Eastern policies, the western powers agreed to the Treaty of Lausanne with the new Turkish Republic, in 1923. This treaty made Tenedos and Imbros part of Turkey, and it guaranteed a special autonomous administrative status there to accommodate the Greeks.

Black Sea and Snake Island	Ukraine Romania	2004	2009	In 2004 Romania filed a case to International Court of Justice claiming that Ukraine's Snake Island was an uninhabitable rock under UNCLOS standards and thus not eligible to carry influence over determination of the maritime boundary between the two states. During the Soviet times the island was a small naval station with a lighthouse. In 2007 the Ukrainian parliament approved an establishment of a small hamlet (settlement) there, Bile, as part of Vylkove city Odessa Region. The maritime boundary issue was settled by the International Court of Justice in 2009.
Vilnius Region	Lithuania Poland	1920	1945	During the Polish-Soviet War Polish armies entered the Vilnius Region which was at the time part of the Soviet Lithuanian-Belorussian Soviet Socialist Republic. In 1920, Polish General Lucjan Zeligowski led a coup and established the Republic of Central Lithuania which was annexed to the Second Polish Republic after the war as part of the historic Polish–Lithuanian Commonwealth and due to ethnic Poles in the region. Lithuania moved its capital to Kaunas while never giving up its claim to Vilnius. The Lithuanians found support in the Soviet Union for their cause signing the Soviet-Lithuanian Mutual Assistance Treaty in 1939. Following the Soviet invasion of Poland, the region came under Soviet control and became part of the Lithuanian SSR after World War II which was followed by a large number of ethnic Poles being deported two times.
