This treaty gave to Portugal the domain of East. This includes parts of South America and Africa.

Explanation:

When it was signed in 1494, Portugal was almost finishing its route to India, and Spain discovered America. The cleary division of the world between these two political powers was necessary to avoid conflicts. Then, Pope Alexander VI decided to create this treaty and gave to these countries the possession of these lands. Under this deal, Portugal received the lands from East, and Spain the other part.
