The Latins, sometimes known as the Latials or Latians, were an Italic tribe that included the early inhabitants of the city of Rome. From about 1000 BC, the Latins inhabited the small region known to the Romans as Old Latium, the area in the Italian Peninsula 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.
