Tribe

Description

From the Wikipedia:

"A tribe, viewed historically or developmentally, consists of a social group existing before the development of, or outside of, states.

Many anthropologists use the term tribal society to refer to societies organized largely on the basis of kinship, especially corporate descent groups (see clan and kinship).

Some theorists hold that tribes represent a stage in social evolution intermediate between bands and states. Other theorists argue that tribes developed after, and must be understood in terms of their relationship to, states." (http://en.wikipedia.org/wiki/Tribe)
