For some ancient civilizations, tattoos were a form of social status: the Inuit population would tattoo girls who have transitioned into womanhood as a sign of their fertility; the Samoans saw tattooing as a painful ritual to transition into a position of leadership; both ancient Greeks and Romans would tattoo slaves and prisoners of war.
Within the cultural significance of tattoos in many ancient civilizations, tattoos were also a form of art and decoration. Art is one of the most consistent forms of communication, so having permanent and personal art - tattoos - on one’s body was a form of expression, whether it be with others or ourselves.
In particular, the Māori population in New Zealand would embellish their faces with elaborate tattoos. Each tattoo was nonpareil and conveyed specific information about a person’s status, ancestry, and abilities. Tattoos were almost like an identity card on people’s skin.
Therefore, while some cultures used tattoos to signify their belonging to a community or a certain rank, others used it to express individuality. However, with colonialism and the forced spread of Christianity, the art form went into decline, deemed savage and unholy.
