Gabriel’s 1800 insurrection plot deliberately borrowed the white revolutionaries’ liberty rhetoric.

Evidence

We see it in Gabriel, who in 1800 conspired to lead an insurrection of the enslaved against their white enslavers, and whose failed plot included a plan to claim the rhetoric of white revolutionaries by purchasing “a piece of silk” for a flag on which to write the motto “Death or Liberty.” — Nikole Hannah-Jones et al., The 1619 Project, 1312
