The South Sandwich Islands is an British overseas territory and a part of the South Georgia. The islands were first spotted in 1775, but they were not established as their own region until 1820. Argentina made a claim on the South Sandwich Islands in 1938, and they continued to debate with the U.K. over ownership until 1982. Since that time, the last Argentinian station was closed and no one has moved to the South Sandwich Islands.
