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, the name of the tripartite ethnic divisions of the original Roman state (Tites, 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".[1] From 241 BC, the Tribal Assembly (comitia tributa) in the Roman Republic was organized in 35 Tribes (4 "Urban Tribes" and 31 "Rural Tribes"). The Latin word as used in the Bible translates Greek phyle "race, tribe, clan". In the historical sense, "tribe", "race" or "clan" can be used interchangeably.
