The Puerto Rican flag was born in New York City as a revolutionary symbol

In short: Adopted in 1895 by exiles, the Puerto Rican flag was designed to mirror the Cuban standard, signaling a unified struggle for independence. While its iconic red, white, and blue design is now official, the specific shade of blue remains a subject of intense debate and political signaling on the island.

The current flag of Puerto Rico emerged from the efforts of the Puerto Rican branch of the Cuban Revolutionary Party, which gathered in Manhattan in December 1895. Seeking to replace the earlier Grito de Lares flag—which was associated with a failed 1868 revolt—exiled activists chose a design that inverted the colors of the Cuban flag. This choice underscored the deep solidarity between the two islands, which were the final remnants of the Spanish Empire in the Americas. The new design was championed by figures like Ramón Emeterio Betances and Juan de Mata Terreforte, who viewed it as a sacred emblem of their shared quest for sovereignty.

The flag's design features five horizontal stripes and a blue triangle with a single white star. While the symbolism is widely accepted—with the star representing the island, the triangle denoting the three branches of government, and the colors signifying liberty and sacrifice—the exact hue of the blue triangle has never been codified by law. This ambiguity has fueled decades of political interpretation. Historically, the independence movement favored light blue, while the government, following the 1952 establishment of the commonwealth, adopted a dark blue similar to the American flag. Since 1995, a medium blue has become the most common choice among the public.

The history of the flag is also marked by competing claims regarding its origin and authenticity. While the 1895 design is the official standard, the earlier Grito de Lares flag remains a point of contention. Only one version of the 1868 flag has been authenticated by primary sources, currently residing in Spain. Other versions, including one held by the University of Puerto Rico, have been dismissed by historians as forgeries. Despite these disputes, the 1895 flag has endured, transitioning from a forbidden revolutionary provocation during the early 20th century to the official symbol of the commonwealth today.
