Final answer:
Following the Treaty of Tordesillas, Spain gained control of most of the Americas, with the exception of Brazil which went to Portugal. Portugal also gained rights to lands in Africa and Asia.
Step-by-step explanation:
The Treaty of Tordesillas, signed in 1494, was an agreement between Spain and Portugal aimed at settling conflicts over lands newly discovered or explored by Christopher Columbus and other late 15th-century voyagers. Under the terms of the Treaty, the land to the west of an imaginary line passing through approximately 370 leagues west of the Cape Verde islands (off the west coast of Africa) was assigned to Spain, and the land to the east of the line was given to Portugal.
As a result, Spain gained control over most of the Americas, excluding Brazil, which was the main area east of the line in the New World and therefore assigned to Portugal. Portugal, on the other hand, gained the rights to the areas that are now Brazil and the lands in Africa and Asia, thus establishing its vast colonial empire in those regions.
