author
A Puerto Rican writer and political thinker, he is remembered for a forceful 1898 work on the island’s relationship with the United States. His writing captures the urgency of a turning point in Puerto Rico’s history.

by Juan B. Nieves
Juan B. Nieves is known for La Anexión de Puerto-Rico a los Estados Unidos de America, a Spanish-language work published in 1898. The book has been preserved by the Library of Congress and Project Gutenberg, which makes it clear that his surviving reputation is closely tied to this political and historical text.
Available book and author listings describe him as a Puerto Rican intellectual and patriot concerned with the history of the island and the consequences of U.S. intervention at the end of the nineteenth century. His work sits in the middle of a major historical transition, and that gives it lasting value for readers interested in Puerto Rico, colonial politics, and the debates surrounding annexation.
Reliable biographical details about his personal life are limited in the sources I could confirm here, so it is safest to present him through the work itself: a writer engaged with the fate of Puerto Rico at a decisive moment in 1898.
