During the Roman administration in the mid-first century AD, Aequum reached the status of an agrarian Roman colony after it was settled by the veterans of Legio VII Claudia Pia Fidelis during the rule of emperor Claudius (41–45 AD).

The city offered colonists from a wider area a place to fulfill their administrative, cultural, religious and social needs and duties.
