Excerpt: Even as the field of reproductive history dedicates greater attention to racial subjectivities and other forms of difference, attention to Native peoples and Indian Country remains limited; this relative absence persists despite Indigenous feminists’ frequent engagement with the topics of pregnancy, childbirth, and motherhood. The cause of such marginalization is not a complete mystery. The marginalization of Native reproductive histories reflects continuing patterns of Indigenous erasure in the context of U.S. settler colonialism and derives from the specificity of tribal nationhood, sovereignty, and Native nations’ trust relationship with the U.S. government, all of which defy tidy integration into the field’s existing narratives. It is also a product of the methodological challenges that these realities pose for nonspecialists. I wrote Reproduction on the Reservation: Pregnancy, Childbirth, and Colonialism in the Long Twentieth Century in part to intervene in these trends. Published in 2019, Reproduction on the Reservation is the first book-length history of reproduction that centers Native American women. It contends that in a nation like the United States, colonialism is a vital frame for understanding histories of reproduction.
