Gens

In ancient Rome, a gens (/ˈɡɛns/ or /ˈdʒɛnz/), plural gentes, was a family consisting of all those individuals who shared the same nomen and claimed descent from a common ancestor. A branch of a gens was called a stirps (plural stirpes). The gens was an important social structure at Rome and throughout Italy during the period of the Roman Republic. Much of an individual's social standing depended on the gens to which he belonged. Certain gentes were considered patrician, others plebeian, while some had both patrician and plebeian branches. The importance of membership in a gens declined considerably in imperial times.

The word gens is sometimes translated as "race" or "nation", meaning a people descended from a common ancestor (rather than sharing a common physical trait). It can also be translated as "clan" or "tribe", although the word tribus has a separate and distinct meaning in Roman culture. A gens could be as small as a single family, or could include hundreds of individuals. According to tradition, in 479 BC the gens Fabia alone were able to field a militia consisting of three hundred and six men of fighting age. The concept of the gens was not uniquely Roman, but was shared with communities throughout Italy, including those who spoke Italic languages such as Latin, Oscan, and Umbrian as well as the Etruscans. All of these peoples were eventually absorbed into the sphere of Roman culture.
