This work explores how after acquiring Puerto Rico in 1898, the United States engaged in a systematic ideological conquest of the population through social science textbooks used in the public school system.

Recently revised to include the latest current events, this classic reference presents the historical, social, political, and cultural aspects of Puerto Rico. Puerto Rico, an island rich with culture and national pride, continues to inspire debate over its designation as a commonwealth of the United States. This updated edition of a popular encyclopedia captures important historical, social, political, and cultural developments of the oldest colony in the world, up to and including the region's current status in relation to the United States. The fascinating work is full of facts, figures, and narratives of the struggles, achievements, and creations of the Puerto Rican people. Essays highlight the area's economy, geography, religion, education, language, radio, television, social media, and films. A focus on the contributions of key historical figures showcase the stories of Ramon Power y Giralt, the first envoy to the Spanish Courts; and Juan Mari Brás, founder of the Puerto Rican Socialist Party, among others. The second edition features recent developments in the commonwealth, including the election of its first female governor, the introduction of the first sales tax, and the financial crisis that shut down schools.

Van Middledyk's work was the first major historical study of Puerto Rico in English. Van Middledyk advanced Puerto Rican historiography by building on the works of Brau, Coll y Toste, and Acosta, and by consulting early Spanish chronicles. A librarian at the Free Public Library of San Juan, Van Middledyk possessed knowledge of and access to considerable primary source material. His history is sympathetic to the Indians and highly critical of Spanish colonial administration. Coming in the wake of American military occupation, the book sought to explain and justify control of the island by the United States.
