A number of other scholars also support the claim that the racialized version of the curse of Ham was devised at that time because it suited ideological and economical interests of the European elite and slave traders who wanted to justify exploitation of African labour. While Robinson (2007) claims that such version was non-existent before, historian David Brion Davis argues, as well, that contrary to the claims of many reputable historians, neither the Talmud nor any early post-biblical Jewish writing relates blackness of the skin to a curse whatsoever.
