Treaty of Tordesillas

Treaty of Tordesillas Period

Spain realized that Portugal's navy was stronger, thus, a military solution was out of the question. Instead, the Spanish monarchs, Queen Isabella of Castile and King Ferdinand II of Aragon, asked the Pope to intervene. Pope Alexander VI issued that Spain could claim any lands not ruled by a Christian king. This was too vague for Spain and Portugal.

The monarchs sent representatives to convince the Pope to give a more conclusive decree. They reminded him that he was from Aragon and if he wasn't helpful then the Spanish would not allow their military to aid him the next time that he needed it, and they would stop donating to the church.

The Line of Demarcation

In 1493, Alexander issued a papal bull that divided the world in two. What was west of this imaginary line would be Spain's to claim while the east was Portugal's. This was called the Line of Demarcation. Portugal already had many ports set up along the east so the line would theoretically not affect them. Or at least that is what the Pope was hoping.

At this point, no one really knew that Christopher Columbus had discovered a route to North America, that wouldn't happen until 1503. In 1506, Pope Julius II ratified the Treaty of Tordesillas.

Pedro Alvares Cabral and Brazil

In an effort to spread Catholicism, the Portuguese sent Pedro Alvares Cabral to follow Vasco de Gama's path around the Cape of Good Hope in Africa. They wanted him to go out a little bit further than de Gama did to see if anything was further out. Cabral landed on the coast of South America in Brazil and claimed it for Portugal in 1500.

Treaty of Tordesillas Purpose

The line did not satisfy Portugal. The king of Portugal knew that he risked excommunication if he attacked Spain. Instead, he sent diplomats. The diplomats argued that the line was too close to the cape of Africa and to avoid currents, Portuguese ships would have to sail into Spanish territory. On June 7, 1494, Spain agreed to move the line back a little bit so that the Portuguese could continue their business.

• The Line of Demarcation divided the non-Christian world, the west was Spain's, and the east was Portugal's
• The Treaty of Tordesillas pushed the line to the west so that Portuguese ships would have room to sail around the southern tip of Africa.

Treaty of Tordesillas Impact and Effects

The Treaty of Demarcation specified that Spain and Portugal could claim land that was not claimed by Christian rulers. Christianity was not global at this point, so European countries could claim lands in Africa and, eventually, the New World.

Brazil is the only country in South America where the primary language is Portuguese and not Spanish. That is because Brazil was the only large landmass that fell within Portugal's territory. If you look at the map above, you will see how Brazil has expanded today, but in 1500, when the first Colony Brazil began, it was within the Portuguese's side of the Treaty of Tordesillas marker.

The Treaty of Tordesillas' Significance

This Treaty prevented war between two powerful countries. Spain and Portugal were able to reach a mutual agreement without resulting in violence and bloodshed.

On the other hand, the Treaty of Tordesillas divided the world into two parts and gave them to Portugal and Spain. It permitted them to go to these places that were already inhabited and take whatever they wanted as long as the people living there were not Christian.

This treaty condoned the horrible things that the Spanish did in the Caribbean, South America, and Central America. It stated that the Portuguese could do no wrong in Africa as long as the people there were not Christians. The effects of this treaty are still felt in the Americas, Africa, and Asia today.
