Liburnia

Liburnia in ancient geography was the land of the Liburnians, a region along the Adriatic coast in Europe whose borders shifted according to the extent of Liburnian dominance at a given time.

Liburnia was south of the Istrian peninsula along the Adriatic coast, though Liburnian dominance may have spread into portions of Istria at times. In Hellenistic and Roman times, the river Titus (now the Krka) marked the southern boundary of Liburnia, dividing Liburnia from the lands of the Dalmatae. If the Katarbates (literally, "Steeply-falling") river mentioned in the Periplus of Pseudo-Scylax (which may date back to the fourth century BC) is the Titus (Krka), then even in earlier times this river would have formed the southern limit of Liburnia.

When the Romans later conquered the region, the delineation of Liburnia as a region became more settled. Liburnia was included in the Dalmatia province.

Lucius Artorius Castus acted as Procurator Centenarius for the region in the late 2nd century after he retired from the Roman military, a reward for his dedicated service.
