CHILEAN ANTARCTIC TERRITORY - ANTARCTICA CHILENA

The Chilean Antarctic Territory or Chilean Antarctica (Spanish: Territorio Chileno Antártico, Antártica Chilena) is the territory in Antarctica claimed by Chile. The Chilean Antarctic Territory ranges from 53° West to 90° West and from the South Pole to the 60° South parallel, partially overlapping the Argentine and British Antarctic claims. It is administered by the Cabo de Hornos municipality in the South American mainland. The territory claimed by Chile covers the South Shetland Islands, Antarctic Peninsula, called "O'Higgins Land" ("Tierra de O'Higgins" in Spanish) in Chile, and adjacent islands, the Alexander Island, Charcot Island, and part of the Ellsworth Land, among others. It has an area of 1,250,257.6 km². Its boundaries are defined by Decree 1747, issued on November 6, 1940, and published on June 21, 1955, the Ministry of Foreign Affairs established

Within Chilean territorial organization Antártica is the name of the commune that administers the territory. The commune of Antártica is managed by the municipality of Cabo de Hornos with seat in Puerto Williams and belongs to Antártica Chilena Province, which is part of Magallanes y la Antártica Chilena Region. The commune of Antártica was created on July 11, 1961, and was dependent on the Magallanes Province until 1975, when the Antártica Chilena Province was created, making it dependent administratively on Puerto Williams, the province capital. 

Chilean territorial claims on Antarctica are mainly based on historical, legal and geographical considerations. The exercise of Chilean sovereignty over the Chilean Antarctic Territory is put into effect in all aspects that are not limited by the signing of the Antarctic Treaty of 1959. This treaty established that Antarctic activities are to be devoted exclusively to peaceful purposes of the signatories and acceding countries, thereby freezing territorial disputes and preventing the construction of new claims or the expansion of existing ones.
