Roman expansion east brought Scupi under Roman rule as a colony of legionnaires, mainly veterans of the Legio VII Claudia in the time of Domitian (81–96 AD). However, several legions from the Roman province of Macedonia of Crassus' army may already have been stationed in there around 29–28 BC, before the official imperial command was instituted. The first mention of the city was made at that period by Livy, who died in 17 AD. Scupi first served as a military base to maintain peace in the region and was officially named "Colonia Flavia Scupinorum", "Flavia" being the name of the emperor's dynasty. Shortly afterwards it became part of the province of Moesia during Augustus's rule. After the division of the province by Domitian in 86 AD, Scupi was elevated to colonial status, and became a seat of government within the new province of Moesia Superior. The district called Dardania (within Moesia Superior) was formed into a special province by Diocletian, with the capital at Naissus. In Roman times the eastern part of Dardania, from Scupi to Naissus, remained inhabited mostly by a local population, mainly from Thracian origin.
