The Introduction explains why nineteenth-century Cuba is a particularly rich context for studying racialism (the assumption that social hierarchies are based on the existence of races), racial doubt (those moments when this assumption gets questioned and racial differences seem less clear), and the different groups of racialized people who mobilized doubt as they worked to reinvent themselves and their society. It also shows how the analysis of the notions at the core of each chapter – racist agnosia, farce, passing-as-open-secret, fictions of racial coherence, back talk, and the reappropriation of Blackness – illuminates present-day critiques of color blindness. Finally, it explains why the book is divided into three parts. The first part focuses on enslaved people’s testimonies and abolitionist writing that attacked illegal slavery by denouncing lies, falsification, and farce; the second one, on free people of color who wrestled with two “one-drop” rules (one which rendered a person not-white, the other which made them whiter); and the third one, on the emergence of Black Cuban writing.
