From an inscription discovered at the beginning of the 14th century in the village of
Grădişte, the new town was settled in the first years after the conquest of Dacia in 106 AD. The inscription reads: "On the command of the emperor
Caesar Nerva Traianus Augustus, son of the divine
Nerva, was settled the Dacian Colony by
Decimus Terentius Scaurianus, its governor." In Rome, the settlement of the colony was marked by the minting of a coin, by order of the Senate, dedicated to emperor Trajan. Possibly built over a temporary camp of the
Fifth Macedonian Legion, it soon was settled by the retired veterans who had served in the Dacian Wars, principally the
Fifth (Macedonia),
Ninth (Claudia), and
Fourteenth (Gemina) legions. It was also settled by veterans and colonists from the Italian peninsula. From the beginning it received the title of
colonia and the status of
ius Italicum. During the reign of
Hadrian the city was renamed Colonia Ulpia Traiana Augusta Dacica Sarmizegetusa. The name was found on a stone inscription that reads "To
Gaius Arrius Quadratus, son of Gaius, acting praetor of the emperor in Colonia Ulpia Traiana Augusta Dacica Sarmizegetusa." Gaius Arrius Antoninus bore the title
legatus pro praetore, the official title of the governor of some imperial provinces of the
Roman Empire. Between 222 and 235 the colony was called a
metropolis. After the
abandonment of Dacia, the population reduced drastically. A small community moved inside the amphitheatre, walling the entrances with funerary stones and surviving until the end of the 4th century. ==The city==
