August 1843

At the National Negro Convention in Buffalo, Henry Highland Garnet delivered 'An Address to the Slaves of the United States,' calling for resistance and work stoppages. The convention, by one vote, rejected publication — Frederick Douglass argued it was too militant. Garnet published it independently in 1848. The address marked a major intellectual turning point: from moral suasion toward direct action as abolition strategy.

Norbert Rillieux, a free Black Creole engineer from New Orleans educated in Paris, received a US patent in 1843 for his multiple-effect evaporator, a device that revolutionized sugar refining by making it safer, cheaper, and more efficient than any previous method. His invention transformed the sugar industry not only in Louisiana but across the world, and the basic principles of his design are still used in modern industrial processes. Rillieux is considered one of the most important chemical engineers in American history.

The National Negro Convention reconvened in Buffalo after a hiatus since 1835, with Henry Highland Garnet, Frederick Douglass, and Charles Lenox Remond as delegates. The convention debated Garnet's incendiary address, Black political party affiliation, and whether the Constitution was a pro- or anti-slavery document. By splitting on these questions, it revealed the maturing complexity of Black political thought and the fracture lines that would define 1850s strategy.

At the National Negro Convention in Buffalo, New York, Henry Highland Garnet delivered a thunderous speech calling on enslaved people to rise up and resist their bondage, declaring 'Resistance! Resistance! Resistance!' The address was so radical that the convention narrowly voted against publishing it, with Frederick Douglass among those opposing its incendiary call to arms. Garnet's speech marked a generational shift toward more militant abolitionism and anticipated the debates over violent resistance that would define the movement's final years.
