Barbarians are particularly prominent in the desert-dwelling human clans, and some of the Horse-Men (tribes of nomads that raise herds of horses on the southern plains.)

With the recent invasions on the southwest coast of the Human lands, there are a larger number of Half-Orcs than ever before, which means that there are increasing numbers of barbarians in the Southlands

Some dwarven tribes also seem to have a tendency towards barbarism.
