According to Priscus, Dacia Ripensis was a flourishing province during the 4th and 5th centuries AD. During the early 440s, however, the Huns captured the province (prior to this, there were conflicts between the Romans and the Huns whereby the latter group captured Castra Martis through treacherous means). Even though the province recovered briefly from Hunnic rule, it was eventually decimated by the Avars in 586. On a more specific note, Aurelian developed Dacia Ripensis on a stretch of the Danube specifically between Moesia Superior and Moesia Inferior.
^ abBury 1923, p. 135: "The date must be A.D. 283, and it is obvious that Aurelian set up the boundary stones, one of which Gaianus restored. There were, then, two Dacias when Diocletian came to the throne and, therefore, Mr. Fillow has inferred that we should read in our List: Dacia <Dacia>, that is presumably Dacia Ripensis and Dacia Mediterranea. Aurelian's Dacia mediterranea might have included Dardania, and Dardania, Mr. Fillow thinks, was split off as a distinct province by Diocletian."
^ abJones 1988, p. 231: "When founded as a colony by Trajan, Ratiaria was within Moesia Superior: when Aurelian withdrew from the old Dacia north of the Danube and established a new province of the same name on the south (Dacia Ripensis), Ratiaria became the capital. As such it was the seat of the military governor (dux), and the base of the legion XIII Gemina. It flourished in the fourth and fifth centuries, and according to the historian Priscus was μεγίστη καί πολυάνθρωπος ("very great and with numerous inhabitants") when it was captured by the Huns in the early 440s. It appears to have recovered from this sack, but was finally destroyed by the Avars in 586, though the name survives in the modern Arcar."
^Maenchen-Helfen 1955, p. 389: "What the Romans could not anticipate was that the Huns would take Castra Martis in Dacia Ripensis by treachery."
^Hind 1984, p. 191: "The emperor Aurelian formed two provinces of Moesia Superior and Inferior. In fact, Dacia Ripensis was formed out of a stretch of the Danube between Moesia Superior and Inferior, while Dacia Mediterranea was the old inland Balkan region of Dardania."
^Eutropius (9.13.1) states that Aurelianus was born in Dacia Ripensis; Historia Augusta (Aurelianus 3.1) supports the birth in Sirmium or Dacia Ripensis, but reports also origins of Moesia (Aurelianus 3.2); Aurelius Victor (Epitome de Caesaribus, 35.1) claims he was born between Dacia and Macedonia.
^Mackay 1999, pp. 207–208: "Lactantius and the Epitome de Caesaribus state that the emperor Maximus was of peasant origin. His birthplace is unknown but his mother's brother, the emperor Galerius, was born in Dacia Ripensis, part of the former province of Moesia Superior (Epit. de Caes. 41.14)."
