Final answer:
The Line of Demarcation and the Treaty of Tordesillas resulted in the New World, or the Americas, being largely divided between Spain and Portugal. Portugal was granted the easternmost region of South America, while the remaining regions of the Americas were allocated to Spain.
Step-by-step explanation:
As a result of the Line of Demarcation and the Treaty of Tordesillas, the New World was divided between Spain and Portugal. The Treaty of Tordesillas was signed in 1494, essentially dividing the 'undiscovered' lands outside Europe between Spain and Portugal along a meridian west of the Cape Verde islands off the coast of Africa. All lands to the east were designated for Portugal while all lands to the west were designated for Spain. This treaty was endorsed by the Pope and was primarily aimed at resolving conflicts over newly discovered lands in the wake of Christopher Columbus's groundbreaking voyage in 1492. This agreement led to Portugal claiming the eastern coast of South America (now part of Brazil), while the rest of the Americas were left to Spain.
