How When Did Puerto Rico Become Part of the United States


The history of Puerto Rico’s relationship with the United States is a complex and multifaceted one. Puerto Rico, an island located in the Caribbean, has a unique status as a territory of the United States. In this article, we will explore the timeline of when Puerto Rico became part of the United States and the various stages of its evolving political status.

The Treaty of Paris (1898):

The connection between Puerto Rico and the United States dates back to the late 19th century. Following the Spanish-American War, which ended in 1898, the Treaty of Paris was signed on December 10, 1898. As part of this treaty, Spain ceded Puerto Rico, along with Guam and the Philippines, to the United States. The transfer of sovereignty marked the beginning of Puerto Rico’s association with the United States.

The Foraker Act (1900):

In 1900, the U.S. Congress passed the Foraker Act (also known as the Organic Act of 1900), which established a civil government in Puerto Rico. This act allowed for the appointment of a Puerto Rican Resident Commissioner to represent the island in Congress, but Puerto Ricans did not have full U.S. citizenship rights at this point.

The Jones Act (1917):

The Jones Act of 1917 granted U.S. citizenship to all residents of Puerto Rico. This was a significant step in the island’s relationship with the United States, as it provided Puerto Ricans with a more formalized status within the American political structure.

Commonwealth Status (1952):

In 1952, Puerto Rico adopted its own constitution and officially became the “Commonwealth of Puerto Rico.” This marked a significant turning point in the island’s political status. Under the Commonwealth arrangement, Puerto Rico had a certain degree of self-governance while maintaining its association with the United States.

Non-Incorporated Territory:

Puerto Rico is considered an unincorporated territory of the United States. This means that while the U.S. Constitution applies to the island, not all federal laws do. Puerto Rico does not have the same representation in Congress as U.S. states, and residents cannot vote in U.S. presidential elections (though they can participate in primaries).

Referendums and Political Debates:

The political status of Puerto Rico has been the subject of ongoing debate on the island. There have been several referendums and plebiscites to gauge the desires of Puerto Rican residents regarding their relationship with the United States. Some residents have advocated for statehood, while others prefer independence or continued commonwealth status. These discussions have yet to result in a change to the island’s political status.


The history of Puerto Rico’s association with the United States is a complex and evolving one. Since the Treaty of Paris in 1898, Puerto Rico has had various political statuses, culminating in its current status as an unincorporated territory of the United States with a Commonwealth government. The ongoing debate over the island’s political future reflects the unique and complex relationship between Puerto Rico and the United States.
