 Cornell and Hartmann outline five additional characteristics that distinguish race from ethnicity: racial identity is typically externally imposed by outsiders, as when whites created the Negro race to homogenize the multiple ethnic groups they conquered in Africa or brought as slaves to America; race is a result of early globalization, when European explorers “discovered” and then conquered peoples with radically different phenotypical traits; race typically involves power relations, from the basic power to define the race of others to the more expansive power to deprive certain racial groups of social, economic, or political benefits; racial identities are typically hierarchical, with certain races being perceived as superior to others; and racial identity is perceived as inherent, something individuals are born with (1998, 27–29).
