It was one of the eighteen richest cities of Italy which the triumviri selected as a reward for their troops.
The triumviri settled some of their veterans here, whence it appears as Colonia Julia Felix Classica Suessa.
It is close to the site of the ancient Aquinum, a municipium in the time of Cicero, and made a colony by the Triumviri, the birthplace of Juvenal and of the emperor Pescennius Niger.
It is mentioned in the war of 41 B.C., and received a colony of veterans under the triumviri (Colonia coniuncta Julia Sutrina).
A colony was founded here either by the Triumviri or by Augustus.
The three leaders met at Bononia and adopted the title of Triumviri reipublicae constituendae as joint rulers.
