Examines how Haiti—as a sovereign Black nation—created a beacon of hope for free and enslaved Black people throughout the African diaspora in the early 19th century. The book argues that free and enslaved Black people in the United States, cognizant of Haiti’s centrality to the global struggle for Black liberation, defended Haiti and its sovereignty eventually giving birth to Black internationalism. This movement both demanded an end to slavery and insisted on full freedom, equality, and sovereignty for Black people throughout the African diaspora.
