Colonizers have been known to antagonize existing ethnic conflicts, or create new ones by promoting one group over another and making sure both groups know why, which ultimately meddles in both local politics and culture. Usually, the so-called "civilized," "developed," and "modern" cultures are either the colonizer's or the colonizer's preferred cultural group. Derogatory language like "uncivilized," "primitive," or "backward" refers to the people being colonized or the more marginal groups. This coding of people and cultural traits as acceptable and unacceptable allows for the mistreatment, enslavement, and genocide of people.
