Baltic Sea | Poland Denmark | 1978 | 2018 | Poland has decided to cede to Denmark 80% of disputed territory | Bregovo | Bulgaria Kingdom of Serbia | 1885 | 1886 | Bulgaria And Serbia briefly had a war over a small border village called Bregovo and this has been the recognized border ever since then | 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 did n'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 . After a British royal commission was sent there in 1812 , the new Governor of Malta Sir Thomas Maitland withdrew British troops and the island was returned to Sicily | Tenedos | Turkey Greece | 1920 | 1923 | On 11 August 1920 , following World War I , the Treaty of Sèvres with the defeated Ottoman Empire granted the island to Greece , who joined the war in Allies ' side in May 1917 . 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 | Northern Ireland | United Kingdom Ireland | 1920 | 1998 | Formerly disputed between Ireland and the United Kingdom since partition on 23 December 1920 , it was settled by the Good Friday Agreement in 1998 , when Ireland amended its constitutional claim . Both countries acknowledged that the territory can join the rest of Ireland if separate referendums in both Northern Ireland and the Republic of Ireland approve of the former 's cession
