After more than four centuries within the Spanish world, the island came under the sovereignty of the United States. The change brought a new government, a new national framework, new institutions—and inevitably, new ideas about how Puerto Rico should fit within them.
But political systems can change much faster than cultures do.
More than a century later, Puerto Rico remains unmistakably Puerto Rican while also having developed for generations within the American nation. That combination did not emerge without friction.
Some traditions adapted. Others disappeared. And a few proved remarkably resistant to replacement.
The Battle Over Language
Perhaps nowhere was that tension clearer than in the classroom.
During the early decades of American government, education became one of the principal instruments through which officials attempted to reshape Puerto Rican society. English was increasingly introduced not simply as another subject to learn, but as a language of instruction.
The logic was understandable from the perspective of the new administration: English could facilitate political and economic integration with the rest of the country.
The problem was that Puerto Rico already possessed a deeply established Spanish-speaking society.
Spanish was the language of families, newspapers, literature, churches, commerce, politics and everyday conversation. Government policy could alter what happened inside a classroom more easily than it could alter what happened around the dinner table.
The experiment ultimately failed to displace Spanish.
English became—and remains—an enormously important language in Puerto Rico. But Spanish survived as the dominant language of daily Puerto Rican life.
That distinction matters. Puerto Rico did not necessarily reject the new language. It rejected the idea that acquiring one required surrendering the other.
A Christmas Season That Would Not End
Culture is also expressed through the calendar.
Puerto Rico inherited from centuries of Spanish Catholic tradition a Christmas season in which January 6—Epiphany, or Día de los Reyes Magos—occupied an important place.
American Christmas culture increasingly brought Santa Claus, December 25 and other traditions into Puerto Rican homes. Puerto Ricans adopted many of them.
But the Three Kings did not disappear.
Children continued leaving grass for the Kings' animals. Families exchanged gifts. Churches celebrated Epiphany. Towns developed public celebrations and festivals.
Puerto Rican Christmas did something characteristic of Puerto Rican culture: rather than simply choosing between two traditions, it absorbed one while preserving the other.
Santa arrived.
The Kings stayed.
The Gallera and the Power of Federal Law
Not everything that survived culturally was permitted to survive legally.
Cockfighting presents a much more complicated example.
For generations, the gallera was a recognized institution in Puerto Rico. Cockfighting was legal, regulated and economically significant. Its history long preceded American sovereignty.
But American attitudes toward animal welfare changed dramatically.
Congress eventually extended the federal prohibition on animal fighting to Puerto Rico and the other U.S. territories. The prohibition took effect in Puerto Rico in 2019 despite substantial local opposition and subsequent legal challenges.
Whether cockfighting should have survived is a separate moral and political question.
Historically, however, the episode illustrates something important about Puerto Rico's relationship with the larger federal system: local tradition does not necessarily prevail when it conflicts with federal law.
The gallera therefore represents something different from the survival of Spanish or Three Kings Day.
The practice could be prohibited.
The memory and cultural argument surrounding it could not.
A Spanish Legal System Inside an American Jurisdiction
Perhaps the most fascinating survival is also one of the least visible.
Puerto Rico never simply discarded its civil-law inheritance and replaced it wholesale with the Anglo-American common-law tradition.
Its legal system became something unusual: a mixed jurisdiction.
Federal constitutional and statutory law, American jurisprudence and institutions created after 1898 became fundamental components of Puerto Rican law. Yet important areas of private law retained foundations inherited from the Spanish civil-law tradition.
The Civil Code remained important. So did the notarial tradition and legal concepts governing property, obligations, succession and family relations.
This means that more than a century after 1898, Puerto Rico's history remains embedded not merely in monuments or museums but in the machinery of everyday life.
A property transaction can contain traces of Spain.
A federal case can contain the United States.
Both can exist within the same jurisdiction.
That is not a historical contradiction. It is the historical reality Puerto Rico produced.
Even Our Names Remember
Then there is something considerably more personal: our names.
Puerto Ricans traditionally use two surnames, reflecting both paternal and maternal family lines.
For anyone researching Puerto Rican genealogy, those surnames can become a roadmap through centuries of baptismal records, marriage certificates, censuses and civil registrations.
But American administrative systems have frequently been designed around a different naming convention: first name, middle name, one last name.
The result can be almost comical.
One surname disappears. Another becomes a middle name. Two surnames become hyphenated. Computer systems occasionally decide that a perfectly ordinary Puerto Rican name must somehow be incorrect.
Yet the convention survives.
It survives because a name is more than a field in a database.
It is genealogy.
It is family.
It is memory.
Culture Is Harder to Govern Than Territory
There is a temptation to tell Puerto Rican history after 1898 entirely as a story of conflict: American versus Puerto Rican, English versus Spanish, old versus new.
Reality is considerably more interesting.
Puerto Rico changed profoundly under American sovereignty. American institutions became Puerto Rican institutions. American popular culture became part of Puerto Rican popular culture. English became part of our educational and professional lives. Puerto Ricans served in the United States military, migrated throughout the country and participated increasingly in a national culture larger than the island itself.
And still, Spanish survived.
The Kings survived.
The two surnames survived.
The civil-law tradition survived.
Other traditions encountered the limits of federal authority and changing national standards.
Puerto Rico therefore offers an extraordinary historical case study in what happens when political integration meets cultural continuity.
A government can change laws.
A school system can change curricula.
A bureaucracy can redesign forms.
Congress can prohibit a practice.
But culture operates differently.
It survives because ordinary people continue speaking it, celebrating it, recording it, teaching it and passing it to their children.
And sometimes the most interesting parts of history are not the things that changed.
They are the things that somehow didn't.
Watch the full episode of Chronicles & Cocktails: “What They Tried to Take Away — and What Puerto Rico Refused to Give Up.”
In the episode, we go deeper into the attempts to change Puerto Rico's language, the survival of Three Kings Day, the controversial history of cockfighting, Puerto Rico's unusual mixed legal system, and even why our two surnames continue confusing American databases more than a century later.
History, culture, a drink—and the complicated story of an American island that learned how to change without forgetting what it was.
