Book excerpt: Hemispheric Blackness and the Exigencies of Accountability examines the way Afrodescendant and Black communities use the land on which they live, the rule of law, and their bodies to assert their historical, ontological, and physical presence across South, Central, and North America. Their demand for the recognition of ancestral lands, responsive policies, and human rights sheds new light on their permanent yet tenuous presence throughout the region. The authors argue that by deploying a discourse of transcontinental historical continuity, Black communities assert their presence in local, national, and international political spheres. This conceptualization of hemispheric Blackness is the driving force confronting the historical loss, dismissal, and disparagement of Black lives across the Américas. Through twelve case studies that cover a wide range of locations, their work examines contemporary manifestations of sovereignty of Black body and mind, Black-Indigenous nexuses, and national revisions that challenge more than a quincentennial of denial and state unaccountability in the hemisphere.
