Prusias ad Hypium/Kieros

Prusias ad Hypium is an important ancient settlement located at the intersection of the ancient regions of Bithynia, Pontus, and Paphlagonia, within the borders of modern-day Düzce province. The city, whose origins date back to the Hellenistic Period, later came under the dominion of the Roman Empire and continued its development as a regional center. Despite its rich history, Prusias ad Hypium, for which no definitive evidence of coinage has been found, continues to offer visitors traces of the past through its archaeological remains today.

History

The history of Prusias ad Hypium extends back to the 4th century BCE, initially emerging as a settlement known by the name Kieros (Cierus). During the Hellenistic Period, the city came under the rule of the Bithynian Kingdom and was renamed Prusias ad Hypium in honor of either King Prusias I (228-182 BCE) or Prusias II (182-149 BCE) of Bithynia. This renaming underscores the strategic and cultural importance the city held for the Bithynian Kingdom.

With the incorporation of the Bithynian Kingdom into the Roman Empire in 74 BCE, following the will of its last king, Nicomedes IV, Prusias ad Hypium was also integrated into the Roman provincial system. During the Roman period, the city underwent significant development and was further strengthened, particularly during the reign of Emperor Claudius (41-54 CE), when it attained the status of a Roman colony. During this era, large-scale construction activities were carried out in the city, and monumental structures such as a theater, aqueducts, and temples were built. The mention of the city's name in the correspondence between Pliny the Younger, governor of the province of Bithynia and Pontus in the 1st century CE, and Emperor Trajan, confirms Prusias ad Hypium's administrative and economic significance during the Roman Empire. The city continued to exist during the Byzantine period and assumed a religious role as an important episcopal see.

Geographic Location

Prusias ad Hypium held a highly strategic location in northwestern ancient Anatolia, at the intersection of the regions of Bithynia, Pontus, and Paphlagonia. Located within the borders of the Konuralp district of modern-day Düzce province, the city became an important center for both terrestrial and maritime trade due to its proximity to the Black Sea coastline. Its establishment in the fertile basin of the Hypius River (modern Küçük Melen) enhanced the city's agricultural production potential and provided easy access to water resources.

This geographic location made Prusias ad Hypium a key stop for trade routes coming from inland regions and heading to Black Sea ports. Among its neighboring cities were important coastal cities such as Tium (Hisarönü) and Heraclea Pontica (Karadeniz Ereğlisi). Its connections with these cities solidified Prusias ad Hypium's place within regional trade and cultural interaction networks. The city's fertile lands also provided a suitable basis for other economic activities such as animal husbandry and forestry.

Significance in Antiquity

In antiquity, Prusias ad Hypium was one of the leading centers of the region, both economically and politically. The fertile agricultural lands surrounding the city were particularly suitable for grain production, making Prusias ad Hypium an important food supply center. Its location on trade routes connecting inland Anatolia to Black Sea ports enabled the city to develop as a trade and transit hub. Thus, Prusias ad Hypium played a significant economic role on both local and regional scales.

Politically, bearing the royal name during the Bithynian Kingdom period indicates the city's high status within the kingdom. After its incorporation into the Roman Empire, it was included in the Roman administrative structure first as a civitas and later as a colonia. These statuses granted the city certain autonomy and privileges, enabling it to become an important administrative center in the region under Roman law and governance. Religiously, the city housed temples and cult sites dedicated to Roman deities. With the spread of Christianity, Prusias ad Hypium became an important episcopal see during the Early Christian period, which further increased the city's influence in religious and cultural life.

Coinage

No coins from this settlement are recorded in the NumisTR database. While many important ancient cities minted their own coins to demonstrate economic independence and political power, it appears that Prusias ad Hypium did not engage in this practice. This suggests that the city's economic activities were primarily conducted using coins minted by neighboring cities or central authorities.
