The Rum Industry: Spirits, Taxes, and Colonial Extraction

Puerto Rico's rum industry — dominated by Bacardí and Don Q (Destilería Serrallés) — is both a source of cultural pride and a case study in colonial economics. Under a unique arrangement, federal excise taxes collected on rum sold in the U.S. are returned ('covered over') to Puerto Rico and the U.S. Virgin Islands. While this generates significant revenue (~$400-700 million annually), the arrangement also creates perverse incentives: mainland corporations receive massive subsidies to locate production in the territories, while the territories depend on an industry controlled by outside capital.

Bomba: The African Heartbeat of Puerto Rico

Bomba is Puerto Rico's oldest living musical tradition — an Afro-Puerto Rican art form combining drumming, singing, and dance that traces directly to enslaved African communities. Unlike most music where dancers follow the music, in bomba the primo (lead drum) follows the dancer — creating a conversation between drummer and dancer that embodies resistance, freedom, and the persistence of African culture through centuries of colonial suppression.

Ponce: The Pearl of the South and Its Architectural Heritage

Ponce — Puerto Rico's second-largest city, founded in 1692 — has historically rivaled San Juan as the island's cultural capital. Known as 'La Perla del Sur' (The Pearl of the South), Ponce's architectural heritage includes Creole, neoclassical, Art Deco, and vernacular styles that reflect the city's history as a center of sugar wealth, liberal politics, and cultural production. The Ponce Historic Zone contains over 1,000 buildings of architectural significance.

At its peak, the military controlled approximately 13% of Puerto Rico's land area.

The Navy used Culebra and its surrounding cays for target practice from 1901 to 1975, when sustained protests by Culebra residents and Puerto Rican activists successfully forced the Navy to relocate its exercises — to Vieques. The Culebra struggle was the first successful anti-military campaign in Puerto Rico and provided the template for the later Vieques movement.

The Birth Control Pill Trials: Puerto Rican Women as Test Subjects (1955-1960)

In the mid-1950s, researchers Gregory Pincus and John Rock chose Puerto Rico as the primary testing ground for the first oral contraceptive pill — Enovid. Puerto Rican women were selected because they were considered 'compliant' subjects, birth control was not illegal in Puerto Rico (unlike many U.S. states), and the colonial population control ideology supported the research. The women were not told they were part of an experiment, were not adequately informed of side effects (which were severe), and three women died during the trials.

Salsa: The Sound of Puerto Rican Diaspora and Global Rhythm

Salsa — the musical genre that conquered the world — was born in the 1960s-70s from the encounter between Puerto Rican, Cuban, and other Caribbean musical traditions in New York City. While Cuba contributed the son and other rhythmic foundations, Puerto Rican musicians, producers, and the Fania Records label in New York were the primary force that created, named, and globalized salsa. From Héctor Lavoe and Willie Colón to Rubén Blades and Celia Cruz, salsa became the soundtrack of Latino identity worldwide.
