What was the purpose of the treaty of tordesillas?

The Treaty of Tordesillas was an agreement made between the Spanish and the Portuguese to solve the confusion that existed related to the newly claimed land concerning the New World.

Explanation:

During the early 1400s, there were some important advances in terms of European exploration. At that time, Portugal tried to find a good water route to communicate with India and China.

In 1492, when Columbus discovered the New World, it seemed that a conflict concerning land claims would appear between Spain and Portugal. The Portuguese's purpose was to keep their monopoly related to the trade with Africa, but they felt threatened. When Columbus found something important, the aspects regarding land became relevant.
