The social and economic history of the Mascarene Islands of Mauritius, Réunion, and Rodrigues must be viewed in the context of regional and global developments including the African diaspora of slave origin and European colonialism in both the Indian Ocean and Atlantic worlds. Mauritius and Réunion’s transformation into plantation colonies during the 18th and early 19th centuries was a complex process shaped by the cultivation of coffee, cloves, cotton, indigo, and sugar; Anglo-French rivalry for domination in the Indian Ocean; a reliance upon domestically generated and controlled capital; the importation of hundreds of thousands of African and Asian slaves from a global catchment area that stretched from West Africa eastward to Southeast Asia; and the increasing socioeconomic importance of the local free population of color during the early 19th century.
