Tribesmen from 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 to refer to societies organized largely on the basis of kinship, especially corporate descent groups (see clan and lineage).

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.

The English word tribe occurs in 13th century Middle English literature as referring to one of the Twelve Tribes of Israel. The word is from Old French tribu, in turn from Latin tribus, referring to the original tripartite ethnic division of the Roman state (Tities, Ramnes, and Luceres, corresponding, perhaps, to the Latins, Sabines, and Etruscans). The term's ultimate etymology is uncertain, perhaps from the PIE roots *tri- "three" and *bhew- "to be".
