The Atacama border dispute was a dispute between Chile and Bolivia in the 19th century that ended in the transfer to Chile of all of the Bolivian Coast and the southern tip of Bolivia's ally Peru through the Treaty of Ancón with Peru and the Treaty of Peace and Friendship of 1904 between Chile and Bolivia after the War of the Pacific (1879–1883). Some consider the dispute is still ongoing as Bolivia still claims a sovereign access to the Pacific Ocean. The conflict takes its name from the Atacama Desert on which lies the disputed territory. From the Chilean annexation of the Bolivian coast in 1879 the Puna de Atacama dispute arose due to Bolivian transfers of land to both Argentina and Chile, this spin-off dispute was settled in 1899. ==Origins== The origins of the dispute came from the borders established in the Spanish empire that just defined the Atacama desert as the northern border of the General Captaincy of Chile. Bolivian and Chilean historians disagree on whether the territory of Charcas, originally part of the Viceroyalty of Peru, later of the Viceroyalty of the Río de la Plata and ultimately of Bolivia, included access to the sea. Supporting their claims with different documents, Bolivians claim that it did while Chileans disagree. When Simón Bolívar established Bolivia as a nation in 1825, he claimed access to the sea, disregarding overlapping claims by Chile, which had gained independence 7 years before. The border dispute between Bolivia and Chile grew slowly during most of the 19th century over the Atacama corridor, a part of the Atacama Desert which now forms northern Chile. The Atacama Desert is bordered by the Coast Range on the west and the Andes on the east. The geography of the area was a very large factor in determining how the border dispute began. Because of the mountains, the area has rains only 2 to 4 times a century, making it one of the driest places on Earth. After the independence of Chile (1818) and Bolivia (1825) none of the following governments of both countries cared about defining its borders. National boundaries in the Atacama region had still not been definitely determined when nitrate, silver and copper deposits were discovered in the area. Both Bolivia and Chile established competing claims for the territory. Other countries' interest was drawn due to the importance of nitrates in the production of fertilizer and high explosives; Britain, Spain and the United States had a strategic and economic stake in controlling the resource granting their support to the different parties. Chile's influence grew in the disputed zone as miners, some of them backed by Chilean and foreign companies, started to advance northwards establishing mines and port facilities. Most economic exploitation of the coastal region was being conducted by Chilean companies and British interests, under the aegis of Chile's more robust economy and more stable institutions. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Atacama border dispute」の詳細全文を読む スポンサード リンク
