In ancient Rome, a gens ( or ), 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.
