Nationa
From Wikipedia, the free encyclopedia

Nationa was an ancient city and bishopric in Roman Africa, which only remains a Latin Catholic titular see.
Nationa, in present Tunisia, was among the many cities in the Roman province of Byzacena, in the papal sway, which became suffragan dioceses of Carthage but faded so completely, plausibly at the 7th century advent of Islam, that no exact site was even identified.
Two of its bishops are historically documented :
- Faustinus, Donatist schismatic without Catholic counterpart at the Council of Carthage in 411, called to discuss the very heresy Donatism with its episcopate and the prevailing Catholics
- Pirasius intervened at the Council of Carthage called in 484 by king Huneric of the Vandal Kingdom, after which he was exiled like most Catholic bishops.[1][2]
