The Latins (Latin: Latini), sometimes known as the Latians, were an Italic tribe which included the early inhabitants of the city of Rome (see Roman people). From about 1000 BC, the Latins inhabited the small region known to the Romans as Old Latium (in Latin Latium vetus), that is, the area between the river Tiber and the promontory of Mount Circeo 100 km (62 mi) southeast of Rome. Following the Roman expansion, the Latins spread into the Latium adiectum, inhabited by Osco-Umbrian peoples.
