Ichi was facial ritual scarification worn by mainly men of the Igbo people of Nigeria.
 The scarification indicated that the wearer had passed through initial initiation into the highest society "Nze na Ozo", thus marking the wearer as nobility.
 The scarification was found among men in the Awka-Nri areas and among a few women in the Awgwu and Nkanu areas.
 Its wearers were authorized to perform ritual cleansing of abominations and to confer titles on people.
 People with facial marks were regarded as Nri men and were less likely to be taken as slaves.
 Other parts of Igbo land may have started wearing Ichi as a result of this.
