South American Antarctic Territory
Population: 1,850,000
Capital: Nueva Esperanza (670,000)
Other cities: Puerto Soberanía, Porto Antártico, Nuevo Cuzco, San Martin
Languages: Spanish, Portuguese
Founded in 23 of march, 2081, after the union of the Peruvian Antarctic Territory, the Brazilian Antarctica, and the Argentine-Chilean Binational Antarctic Territory (founded in 2063), plus the countless Uruguayan, Colombian, and Venezuelan bases and ports.
In the year of 2098 an administrative and territorial reform is made, which led to the creation of new provinces, granting them greater autonomy and economic freedom, being governed directly by the Council of South American Nations (CONASUR).
Today, the South American Parliament is discussing and planning the independence of the Antarctic Territory; if that happens, it is expected to occur within the next five years. A popular consultation in the primary bases and cities of the Antarctica (colloquial name of the Territory) indicated that over 76% of the population is in favor of independence. An official referendum is programmed by 2117 and the first presidential elections by 2120. If it were to gain independence, the new country would be named Federal Republic of Antarctica.
It's pretty precise. As a Spanish-speaker, I can confirm that Spanish is a weird language.
