Empire’s Progeny is a collaborative research and learning project through which students interrogate historical conceptions of human difference and how these were integrated into structures of power over the course of the colonization of the Americas.  Together and individually, participants collect, synthesize, and analyze dozens of sources that speak to the development of socioracial ideas and practices and to how colonial subjects negotiated and contested racialized imperialism. We assemble these sources into a shared database and then map them in time and space to comprehend the temporal and geographical diversity of racial experience throughout history. Through discussion and writing, we develop shared and individual interpretations of the relationship between imperialism and race in the Americas and the meaning of this history for the 21st century.
