What rights did slaves have in the United States prior to abolition?

by Not_vlad_putins_KGB

We have all been taught about the atrocious treatmeant of slaves in the American south with regards to their basic human rights. I recently learned about the treatmeant of slaves in ancient Rome, where a slave could be killed by their master with no questions asked. Considering slavery continued in the United States well into the post-englightenment age, were black slaves granted any sort of rights "guaranteed" by law or even common social norms?

P.S. it's "guaranteed" because I doubt an 1854 South Carolina jury would give a fair and honest trial to a slave.
