Slavery [SEP] Legal rights
Depending upon the era and the country, slaves sometimes had a limited set of legal rights. For example, in the Province of New York, people who deliberately killed slaves were punishable under a 1686 statute. And, as already mentioned, certain legal rights attached to the nobi in Korea, to enslaved people in various African societies, and to black female slaves in the French colony of Louisiana. Giving slaves legal rights has sometimes been a matter of morality, but also sometimes a matter of self-interest. For example, in ancient Athens, protecting slaves from mistreatment simultaneously protected people who might be mistaken for slaves, and giving slaves limited property rights incentivized slaves to work harder to get more property.
