This dissertation is an interdisciplinary project that introduces vocabulary, analytic units and cultural landscapes that make it possible to conceive of slavery and settler colonialism as constitutive of one another. By focusing on Black female gender formation at the intersection of slavery and settler colonialism, this study argues that Black women's bodies function as sites where we can observe the power of slavery and settler colonialism simultaneously. Both the Slave Master's need for bodies and the Settler's need for space required the production of the Black female slave body as a unit of unending property. As a metonym for fungible property, the Black female slave body served as an apt metaphor for space within settler colonial imaginaries. Though largely omitted from the analytic frames of settler colonialism, Black women's bodies are materially and symbolically essential to the space making practices of settler colonialism in the US and Canada.
