East Patagonia, Tierra del Fuego and Strait of Magellan Dispute
Argentina-Chile sovereignty dispute between 1842 & 1881 / From Wikipedia, the free encyclopedia
The East Patagonia, Tierra del Fuego and Strait of Magellan Dispute[1] or the Patagonia Question was the boundary dispute between Argentina and Chile[2] during the 19th century[3] for the possession of the southernmost territories of South America[4] on the basis of disagreements over the boundaries corresponding to the uti possidetis juris inherited from the Spanish Empire.[5][6][7]
The extensive territory corresponds to approximately one million two hundred km²,[8][9] which represent 45% of the current surface of Argentina, all of the center and south of that country, and which, according to Chilean historiography, would have implied a loss for Chile[10][11] of two-thirds of its nominal territory de jure.
