Mount Circeo in the context of "Promontory"

The Latins (Latin: Latīnī), sometimes known as the Latials or Latians, were an Italic tribe that 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), 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.

Their language, Latin, belonged to the Italic branch of Indo-European. Speakers of Italic languages are assumed to have migrated into the Italian Peninsula during the late Bronze Age (1200–900 BC). The material culture of the Latins, known as the Latial culture, was a distinctive subset of the proto-Villanovan culture that appeared in parts of the Italian peninsula in the first half of the 12th century BC. Before and after their political unification under Rome in 338 BC, the Latins maintained close cultural and religious relations, including common festivals and religious sanctuaries.

Latium Vetus or Latium Antiquum (English: Old Latium) is a region of the Italian Peninsula bounded to the north by the Tiber River, to the east by the central Apennine Mountains, to the west by the Mediterranean Sea and to the south by Monte Circeo. It was the territory of the Latins, an Italic tribe which included the early inhabitants of the city of Rome. Later it was also settled by various Italic tribes such as the Rutulians, Volscians, Aequi, and Hernici. The region was referred to as "old" to distinguish it from the expanded region, Latium, that included the region to the south of Old Latium, between Monte Circeo and the river Garigliano – the so-called Latium adiectum ("attached Latium"). It corresponded to the central part of the modern administrative region of Lazio, Italy, and it covered an area measuring of roughly 50 Roman miles. It was calculated by Mommsen that the region's area was about 1860 square kilometres.

Gaius Julius Iullus (fl. c. 489 BC) was a Roman politician from the early Republic. He was the first from the ancient patrician clan of the Julii to attain the consulship, which he held in 489 BC as the colleague of Publius Pinarius Mamercinus Rufus.

According to Dionysius, it was during their year of office that the Volscian leader Attius Tullius provoked a confrontation with Rome. With the help of the Roman exile Coriolanus, the Volsci prepared for war and began raiding Latin territory. As planned, the impact of the Volscian operations fell more heavily on the poor, exacerbating the already tense relationship between the patricians and the plebeians. As the Senate was trying to calm the populace, a Volscian force under Coriolanus took control of the city of Circeii, where there was a Roman colony. The consuls were directed to set a watch over the city, call upon Rome's allies for help, and begin raising an army to meet the Volscian threat, but their term of office expired before these tasks could be completed. It fell to their successors to continue preparing for the inevitable confrontation with Coriolanus.

Circeii was an ancient Roman city on the site of modern San Felice Circeo and near Mount Circeo, the mountain promontory on the southwest coast of Italy. The area around Circeii and Mount Circeo was thickly populated with Roman villas and other buildings, of which the remains of many can still be seen.

The origin of the name is uncertain: it has naturally been connected with Homer's legend of Circe. The difficulty has been raised that the promontory ceased to be an island well before Homer's time; but Procopius remarked that the promontory has all the appearance of an island until one is actually upon it.
