This is a classic study of the early period of Spanish rule in Puerto Rico, covering the years 1493-1550. This is a difficult period to research because of the dearth of sources. In this work, Brau, 1842-1912, provided the reader with valuable information on the impact of Spanish society on the native peoples of the island, and he showed considerable sympathy for their plight. Brau introduced each chapter with a summary, and his appendixes include copies of important original documents (letters, reports) for the study of the island's history.
