A barbarian is a human who is perceived to be either uncivilized or primitive. The designation is usually applied as generalization based on a popular stereotype; barbarians can be any member of a nation judged by some to be less civilized or orderly, but may also be part of a certain "primitive" cultural group or social class both within and outside one's own nation. Alternatively, they may instead be admired and romanticised as noble savages. In idiomatic or figurative usage, a "barbarian" may also be an individual reference to a brutal, cruel, warlike, and insensitive person.
