Puerto Rico is a political paradox: part of the United States but distinct from it, enjoying citizenship but lacking full political representation, and infused with its own brand of nationalism despite not being a sovereign state. More than a century after being acquired by the United States from Spain, the island continues to grapple with its status as a U.S. territory and the legacy of colonialism in the Caribbean.

The debate over Puerto Rico’s statehood remains as relevant as ever, as the island struggles with the combined effects of economic depression, shrinking population, debt crisis and bankruptcy, natural disasters, the COVID-19 pandemic, and government mismanagement. A major deal to restructure debt has raised hopes that the island is on a path to economic recovery, while supporters of statehood have pressed for a binding referendum on the island’s status.

What is Puerto Rico’s Historical Backdrop?
Christopher Columbus reached the island that would become Puerto Rico, then home to the Taíno people, in 1493, ushering in more than four hundred years of Spanish rule. It became a critical military outpost, allowing Spain to defend its New World colonies against other European powers. By the eighteenth century, Puerto Rico had become a major exporter of tobacco, coffee, and sugarcane. Yet discontent with colonial rule led to a growing independence movement on the island, and Spain granted Puerto Rico self-government in 1897.

Just months later, however, the United States invaded the island during the 1898 Spanish-American War as part of a broader effort to push Spain out of the Caribbean and the Pacific. Spain lost the war and ceded Puerto Rico to the United States, along with other territories, including Guam and the Philippines.

How Has Its Relationship with the United States Evolved?
A raft of legislation and court rulings in the early twentieth century forged a unique relationship between Washington and its Caribbean territory. After two years of direct U.S. military rule, the 1900 Foraker Act reestablished a civilian government and specified Puerto Rico’s territory status. While it had an elected legislature, the U.S. president appointed the island’s governor and other major officials. The Foraker Act also granted Puerto Ricans a nonvoting representative in Congress, but not citizenship. Ambiguity over the island’s status was fueled by Supreme Court cases [PDF] that declared it an unincorporated territory with no clear path to statehood.
