Negrescence is a word with a Latin origin. It describes a process of becoming black or developing a racial identity. It can also refer to having a dark complexion. Negrescense extends through history by those victimized by racism and white supremacy. Psychological adaptations instigated identity formation for persons of African American descent. This analysis was used to support Beddoe's theory that the Irish had the physical characteristics of the indigenous, aboriginal people of the British Isles. Bailey Jackson created a four stage nigrescense model.
