According to the Papal Bull Inter caetera, issued by Pope Alexander VI on 4 May 1493, the dividing line between the crowns of Spain and Portugal had found the longitude 36 º 8'O, cutting South Georgia (according to other sources in longitude 35 º W). But with the entry into force of the Treaty of Tordesillas in 1494, the island was in the Portuguese hemisphere. Regarding the South Sandwich Islands, both the bull and the Treaty were within the Portuguese hemisphere.
