How US imperialism affected Puerto Rico

Puerto Rico was a result of the Spanish-American War. This territory has caused the most controversy and discussion in regards to its status than any other U.S. territory. They officially were considered a commonwealth of the U.S. on July 25, 1952. This happened when its new flag was raised by its governor at the time. Even though it is considered a Commonwealth of the U.S; it is still subject to U.S. laws and U.S. policy in regards to its legal status and security.

Here is a picture of Puerto Rico's flag.

Open Door Policy

The Open Door Policy was an idea that all nations should be able to trade with China equally.


This policy played a role in the imperialism of Puerto Rico because it allowed them to be able to trade with China. Any country that was able to trade with China was in good shape. This was because China had a lot of stuff that other countries needed. So if you could get them to trade with you then you would have a lot of products that other countries wish the could have.

Treaty of Paris 1898

The Treaty of Paris 1898 ended the Spanish American War or the 'splendid little war' as John Hay called it.


This treaty played a very favorable role for the United States. The reason it was so favorable was because Spain had to give up all claims to Cuba, the U.S. gained territory in Puerto Rico and Guam, Spain turned over the Philippines for $20 million. These territorial gains strengthened the military and economic position of the U.S tremendously. John Hay called the Spanish American War the 'splendid little war' because it didn't cost a lot of money for the U.S.
