Pax Julia
Roman city in Lusitania
Pax Iulia (also known as Colonia Civitas Pacensis) or later Pax Augusta was a city in the Roman province of Lusitania (today situated in the Portuguese municipality of Beja).
History
The region was inhabited during 400 BC by Celtic tribes, but there are indications that Carthaginian settlers occupied the territory, from the writings of 2nd century scholars Polybius and Claudius Ptolemy..
In 48 BC, it was renamed Pax Iulia (referring to the "peace of the gens Julia") by Julius Caesar following the peace between Rome and the Lusitani. The settlement became the centre of the conventus iuridicus Pacensis, (in the Roman province of Lusitania), since it was located on a strategic roadway junction with connection Myrtilis Iulia (a harbor city along the Guadiana river).
Sometime between 31 and 27 BC, during the reign of the emperor Augustus, the city was granted the status of municipium following the Battle of Actium, and the colonists ascribed to the gens Galeria. It was at this time that a new designation began to appear: Pax Augusta (referring to the peace of Augustus) as mentioned by Strabo.
20th century
Archaeological excavations during the 20th century uncovered the remains of a large Roman temple, 30 by 19.4 metres (98 ft × 64 ft), dating to the first century AD located within the settlement's forum, with several inscriptions, Roman arches, fortifications and an aqueduct. Possible locations for the theater and amphitheater were deduced from the urban layout.

Why this record matters
The phrase “roman city in Lusitania” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The strongest evidence will usually combine a dated visual record with documents produced by the authority responsible for the place. The source revision retrieved here is dated Jul 20, 2026. The linked authority identifier is Q2629210. Authority coordinates are 38.018, -7.865. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
