The II Antofagasta Region ((スペイン語:II Región de Antofagasta)) is one of Chile's fifteen first-order administrative divisions. It comprises three provinces, Antofagasta, El Loa and Tocopilla. It is bordered to the north by Tarapacá and by Atacama to the south and is the second-largest region of Chile. To the east it borders Bolivia and Argentina. The capital of the region is the port city of Antofagasta, another important city being Calama. The main economic activity is copper mining in the giant porphyry copper systems located inland. Climate is extremely arid albeit somewhat milder near the coast. Nearly all of the region is devoid of vegetation except close to the Loa River or at oases such as San Pedro de Atacama. Much of the inland is covered by salt flats, tephra and lava flows. The coast exhibits prominent cliffs. The region was sparsely populated by indigenous Changos and Atacameños until massive Chilean immigration in conjunction with a saltpeter boom in the later 19th century. The region used to be Bolivian until the War of the Pacific broke out in 1879. ==History== Antofagasta's history is divided, as the territory, in two sections, the coastal region and the highlands plateau or altiplano around the Andes. In pre-Columbian times, the coastline was populated by nomadic fishing clans of Changos Indians, of which very little is known, due to very limited contact with the Spanish conquerors. The inland section was populated by the Atacaman culture around the great dry salt lake called Salar de Atacama, the Loa River basin and valleys and oasis across the altiplano, with the most important settlement being the village of San Pedro de Atacama. The Atacaman culture was deeply influenced by Tiwanaku culture and later fell under Inca rule. Atacamans' harvested mainly corn and beans and developed trade as far as the Amazon basin and Pacific shores. The arrival of the Spaniards in the 16th century did not destroy the culture but transformed it deeply through the process of mestizaje, in which both cultures mixed. Under the Spanish rule, Atacaman territory (only the interior), was placed under the administration of Charcas Audience and at the time of independence general Simón Bolívar integrated (both inland and coast regions) into the new Republic of Bolivia, under the name of "Litoral Department". This decision was disputed by the Chilean Government and has been a source of conflict until present times. Chile claimed that according to the Uti possidetis of the Spanish crown, the coastal region belong to them and their territory bordered directly with Peru. Chileans explorers such as Juan López and José Santos Ossa discovered rich nitrate and guano deposits which produced a massive Chilean colonization of the coastline. Friction between the new settlers from both countries grew until 1879 when the War of the Pacific erupted. Antofagasta was permanently annexed by the Chilean government at the end of the war. Colonization by Chileans followed mainly from the "Little North" (the contemporary regions of Atacama and Coquimbo, also known as the III and IV regions), into the new territories of Antofagasta and Tarapacá, nicknamed the ''Norte Grande'' or "the Great North". In the early 20th century the region became a significant base of Chile's union-organizing movements. It continued to depend economically on the nitrate-extraction industry until its replacement by copper mining. Two of the largest and richest open pit mines in the world are located in Antofagasta: La Escondida and Chuquicamata. 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「Antofagasta Region」の詳細全文を読む スポンサード リンク
