The Romans granted Dougga the status of an indigenous city (Latin: civitas) following their conquest of the region.

The creation of the colony of Carthage during the reign of Augustus complicated Dougga's institutional status.
The city was included in the territory (pertica) of the Roman colony, but around this time, a community (pagus) of Roman colonists also arose alongside the existing settlement.
For two centuries, the site was thus governed by two civic and institutional bodies: the city with its peregrini and the pagus with its Roman citizens.
Both had Roman civic institutions: magistrates and a council (ordo) of decurions for the city, a local council from the end of the 1st century AD, and local administrators for the pagus, who were legally subordinated to the distant but powerful colony of Carthage.
In addition, epigraphic evidence indicates that a Punic-style dual magistracy, the sufetes, achieved some civic stature here well into the imperial period.
In fact, the city once had three magistrates serve at once, a relative rarity in the Mediterranean.

Over time, the romanization of the city brought the two communities closer together.
Notable members of the peregrini increasingly adopted Roman culture and behavior, became Roman citizens, and the councils of the two communities began to take decisions in unison.
The increasing closeness of the communities was facilitated at first by their geographic proximity—there was no physical distinction between their two settlements—and then later by institutional arrangements.
During the reign of Marcus Aurelius, the city was granted Roman law; from this moment onward, the magistrates automatically received Roman citizenship and the rights of the city's inhabitants became similar to those of the Roman citizens.
During the same era, the pagus won a certain degree of autonomy from Carthage; it was able to receive bequests and administer public funds.

Nonetheless, it was not until AD 205, during the reign of Septimius Severus, that the two communities came together as one municipality (municipium), made "free" (see below) while Carthage's pertica was reduced.
The city was supported by the euergetism of its great families of wealthy individuals, which sometimes reached exorbitant levels, while its interests were successfully represented by appeals to the emperors.
Dougga's development culminated during the reign of Gallienus, when it obtained the status of a separate Roman colony.

Dougga's monuments attest to its prosperity in the period from the reign of Diocletian to that of Theodosius I, but it fell into a sort of stupor from the 4th century.
The city appears to have experienced an early decline, as evidenced by the relatively poor remains of Christianity.
The period of Byzantine rule saw the area around the forum transformed into a fort; several important buildings were destroyed in order to provide the necessary materials for its construction.
