Answer 2

Answer:

splitting of the lands between themselves

Explanation:

The dispute between Spain and Portugal over the lands in South America was settled with the signing of the Treaty of Tordesillas which saw south America divided equally along the Atlantic ocean between Spain and Portugal.

All the lands west of the line was given/controlled by the Spanish while all lands lying to the west of the Cape Verde islands / east of the line was controlled by the Portuguese. this helped to end the dispute  between both nations on who owes the lands in South America.
