In the olden days, when a child is born, the proud father will want the child to be given tribal marks as a way of expressing that he is the legitimate father of the child as well as a way of identifying the child in their family lineage or ethnic group. It is believed that the best way of identifying people of same ethnic group is the similarity of their marks and in that case, they protect their interest.
Tribal marks which can also be described as facial marks though well dominated in Africa, can be traced to some foreigners who were living in Egypt in the 5th century BC. During that time, a Greek historian, Herodotus wrote about some foreigners living in Egypt who cut their foreheads with knives to differentiate themselves from the Egyptians. This practice was further adopted years later when several kings of various kingdoms in Africa, started invading other kings and their people for land and other resources. The invaders therefore mark themselves as well as their family members to differentiate themselves from the captured kings and their family members whom they now regard as their slaves.
