When these societies do not possess distinctions of rank, they are described as egalitarian.
In scientific literature covering native African societies and the effect of European colonialism on them the term is often used to describe groups of people living in a settlement with "no government in the sense of a group able to exercise effective control over both the people and their territory". In this respect the term is also often used as synonymous to "stateless society". Such societies are described as consensus-democratic in opposition to the majority-democratic systems of the West.
