Karousa/Polichnion is an ancient settlement that was part of the historical landscape of the Pontus and Lesser Armenia regions, stretching along the strategic Black Sea coast in the northeastern part of ancient Anatolia. This city was situated within the dynamic structure of the region, particularly during the period of the powerful Kingdom of Pontus's resistance against the Roman Empire, holding a significant geographical position during the Hellenistic and Roman periods. Located within the borders of modern Turkey today, this ancient city contributes to the understanding of Anatolia's rich archaeological and numismatic heritage.

History

While precise information regarding the foundation of Karousa/Polichnion is limited, it is believed to have followed a trajectory parallel to the general historical development of the region. The regions of Pontus and Lesser Armenia came under the influence of various local kingdoms and powers from the mid-1st millennium BCE onwards. Following the dominion of the Persian Empire, a new structuring process began in the region with the conquests of Alexander the Great and the onset of the Hellenistic Period. Settlements like Karousa/Polichnion came under the influence of Hellenistic culture during this period, beginning to develop administratively and culturally.

The region's most flourishing period was experienced with the Kingdom of Pontus, established in the late 3rd century BCE and reaching its zenith during the reign of King Mithridates VI Eupator (120-63 BCE). It is probable that Karousa/Polichnion was also a part of this kingdom's political and military network. Mithridates's protracted wars against Rome placed the region at the center of political turmoil. The city was utilized as a strategic point during these wars, perhaps serving as a garrison or a logistical support center. Following the collapse of the Kingdom of Pontus, Karousa/Polichnion came under the dominion of the Roman Empire and was likely integrated into the administrative structure of Rome's provinces of Pontus and Bithynia, Galatia, or Cappadocia. The peace and stability (Pax Romana) in the region during the Roman period may have contributed to the city's development. It is thought to have continued its existence during the later Byzantine period, though detailed information regarding its significance is limited.

Geographic Location

Karousa/Polichnion is situated at the intersection of the Pontus and Lesser Armenia regions, which stretch along the southern coast of the Black Sea and feature mountainous and rugged terrain, at coordinates 41.810138 latitude and 35.158944 longitude. This location provided the city with a significant strategic advantage in antiquity. Its proximity to the Black Sea offered access to maritime trade routes, while it was also likely situated on land routes connecting the interior regions with the coastal strip. The natural geography of the region may have enhanced the settlement's defensive potential; the name "Polichnion," meaning "small city" or "fortified place," could indicate this defensive characteristic.

The Pontus region possesses a geography known for its fertile valleys and rich forested areas. It can be assumed that Karousa/Polichnion also benefited from these natural resources, contributing to the regional economy through agricultural production or forestry activities. While there is no clear information regarding its relations with neighboring major cities, it can be presumed to have been in commercial and cultural interaction with important centers in the region such as Amaseia, Neocaesarea (Niksar), or Comana Pontica. This geographical location allowed the city to function as a transit and control point on both a local and regional scale.

Significance in Antiquity

The significance of Karousa/Polichnion in antiquity is largely linked to the strategic location of the Pontus and Lesser Armenia regions where it was situated. This region was a constant area of contention due to its position controlling Black Sea trade, acting as a gateway to the Anatolian interior, and lying on transit routes between east and west. Although Karousa/Polichnion was not a major metropolis, its name ("Polichnion") suggests it likely functioned as a regional administrative or military garrison center. As a small town or fortified settlement, it may have undertaken duties such as ensuring the security of surrounding rural areas, collecting local taxes, or hosting military units.

Particularly during the Kingdom of Pontus period, in the struggles against Rome, settlements like Karousa/Polichnion may have become important nodal points within the kingdom's defense network. It may have assumed roles such as providing logistical support, securing communication lines, or serving as a base for small-scale military operations. Even after coming under Roman rule, as part of the provincial administration, it may have maintained its importance as a local center for ensuring regional order and security. Economically, its location on the Black Sea coast likely contributed to fishing or maritime transport, and it may have played a role in the local economy through activities such as the processing and trade of agricultural products or mineral resources (if any) from the interior. From a religious perspective, it may have hosted small temples or sacred areas where local cults specific to the region, or later the worship of Hellenistic and Roman deities, were practiced.

Coinage

No coins from this settlement are recorded in the NumisTR database. Numismatic data indicate that this settlement did not strike coins in its own name. This suggests that the city did not possess independent economic authority in antiquity, nor was it a major administrative center with the privilege of minting coins. Typically, the right to mint coins was granted to important trade centers, provincial capitals, or major cities at the heart of kingdoms. Smaller or strategically military settlements like Karousa/Polichnion generally used coins struck by larger cities in their vicinity or by imperial authorities. The coins in circulation in the region likely consisted of issues struck at various mints of the Kingdom of Pontus or the Roman Empire. This indicates that the city's economic activities were integrated into regional and imperial monetary policies, but it did not feel the need to express its local identity through coinage, or it lacked the authority to do so.

Archaeological Remains

Detailed and extensive information regarding the archaeological remains visible today at Karousa/Polichnion is limited. This suggests that the city may not have undergone comprehensive archaeological excavation, or that the remains may have been buried over time or destroyed. However, the name "Polichnion," meaning a "fortified place," may indicate the presence of architectural remains such as city walls or defensive structures at the settlement at some point. Surface surveys or future archaeological work could provide important information regarding the city's settlement plan, architectural structures (residences, public buildings, temples), necropolis areas, and ceramic finds offering clues about daily life. It is probable that fundamental structural remains, water systems, and road traces, typical of an ancient settlement, would also be found at Karousa/Polichnion. The remains of such settlements may often consist of wall traces at foundation level, building stones, and architectural elements preserved underground.

Today

The ancient settlement of Karousa/Polichnion is located today within the borders of modern Turkey, in the interior parts of the Black Sea Region. Information regarding precisely which modern settlement the city lies beneath or near is not detailed in existing databases. This situation suggests that, like many ancient settlements in the region, Karousa/
