Prejudice plagues nations across the world, and the Dominican Republic is by no means immune. This paper examines La Raza—the prejudicial ideology that has consumed the Dominican Republic since the colonial era. La Raza, which has had extensive influence on the actions of Dominican leaders since the nation’s inception, is rooted in anti-African and anti-Haitian biases. Specifically, La Raza’s doctrine clearly delineates between Dominican identity and Haitian identity, categorically casting the former as better than the latter. Haitian-Dominican communities, however, have complex identities that do not adhere to La Raza’s racial ideals. Accordingly, Dominican government leaders have employed the ideology to persecute those of Haitian descent within the Dominican Republic. Current literature extensively analyzes the use of La Raza in specific periods, but much less is done to portray La Raza as a continuing force. This is an important gap in the understanding of anti-Haitian prejudice in the Dominican Republic because it fails to showcase the true extent to which this form of racism is present in the country. This paper contends that the concept of La Raza has inflicted a continuous injury on Haitians throughout Dominican history, addressing a crucial gap in the scholarship. This position is substantiated through an analysis of key events such as the Haitian occupation of 1822 to 1844, the 1937 Massacre, and the more recent 2013 Dominican Tribunal Ruling. In doing so, the research provides a crucial framework for analyzing the enduring impact of anti-Haitian racism on Dominican identity and policy, contributing a vital perspective to the discourse on racial formation in the Caribbean.
