This document from Project Gutenberg, “The Suppression of the African Slave-Trade to the United States of America 1638–1870” by W.E.B. Du Bois, explores the historical arc of the slave trade and its attempted suppression in the United States. It examines colonial trading practices, restrictions implemented (and often circumvented) by various colonies and states, and the evolving legal and political landscape surrounding slavery. The text covers significant periods such as the Revolution, the early debates in Congress, and the impact of events like the Haitian Revolution. Furthermore, it details the international efforts to abolish the trade, including treaties and the challenges of enforcement, as well as the economic forces that shaped the institution of slavery. The appendix provides a chronological overview of relevant colonial and state legislation. The author concludes with reflections on the compromises made and the ultimate failure to address the moral wrong of slavery, leading to a civil war.
