Amazons from the Brazilian rainforest
Two years after the discovery of the New World, on June 7, 1494, it was divided (without anyone asking the natives). In the so-called Treaty of Tordesilla, the Pope established a dividing line from north to south, which ran 370 miles from the Cape Verde Islands. To the east of this axis fell the newly discovered territories of Portugal, to the west of Spain. That's why Portuguese is spoken in Brazil and Spanish in the rest of South America.
