Kotiaeion is the ancient name for modern Kütahya and an important Phrygian city whose history dates back to 3000 BCE. Known by its name, meaning "City of Kotys," this settlement played a key role on Anatolia's ancient trade routes thanks to its strategic location. During the Roman Empire, it became part of the province of Phrygia Salutaris, and in the Byzantine period, it was fortified with double walls by Emperor Justinian I.

History

The origins of Kotiaeion trace back to early Bronze Age settlements in the lands of modern Kütahya, dating to 3000 BCE. The city was settled by the Phrygians around 1200 BCE and took its name from the goddess Kotys during this period, indicating the city's early cultural and religious significance. Around 676 BCE, the city suffered a Cimmerian invasion, subsequently falling under Lydian and Persian rule. Following Alexander the Great's conquests, Kotiaeion changed hands among Hellenistic kingdoms, finally coming under the control of the Roman Empire in the 1st century BCE. During the Roman period, it became an important center of the province of Phrygia Salutaris, and with the spread of Christianity, it became an episcopal see. Traditionally, the famous fabulist Aesop is believed to have been born here. During the reign of Byzantine Emperor Justinian I, it was strengthened with double walls, particularly for defense against the Sasanian Empire. After the Battle of Manzikert in 1071, Kotiaeion came under the dominion of the Seljuk Turks, later becoming the capital of the Germiyanid Beylik, and was definitively incorporated into the Ottoman Empire in 1428.

Geographic Location

Kotiaeion is located in Inner Western Anatolia, in the central position of modern Kütahya province. The city's coordinates are 39.418148 north latitude and 29.984511 east longitude. This strategic location made it a crossroads for important trade and military routes in antiquity. Situated in the heart of the Phrygian region, Kotiaeion lay on the main route connecting Western Anatolian cities like Ephesus and Sardis to Ankara and Inner Anatolia. Its establishment at a point where fertile plains meet mountainous terrain provided both agricultural potential and ease of defense. Surrounding rivers and natural resources contributed to the city's economic development, while also increasing its interaction with neighboring cities. This central location is one of the primary reasons why the city remained an attractive settlement for many civilizations over centuries.

Significance in Antiquity

Kotiaeion's significance in antiquity is closely linked to its geographic location and profound history. As one of Phrygia's important centers, it influenced the region's cultural and religious life. Its name, meaning "City of Kotys," provides a strong indication that it may have been a cult center dedicated to the Phrygian goddess Kotys. During the Roman Empire, it became one of the key administrative and military cities of the province of Phrygia Salutaris. Its location at the crossroads of strategic routes made the city both a vibrant commercial hub and an important base for military movements. Its fortification with double walls by Emperor Justinian I clearly demonstrates the city's critical role in the Byzantine Empire's eastern defense line. Furthermore, its mention as the birthplace of the fabulist Aesop also bestowed cultural prestige upon Kotiaeion. This multifaceted importance ensured the city a lasting place in the history of ancient Anatolia.

Coinage

No coins from this settlement are recorded in the NumisTR database. Historical records and archaeological findings do not provide clear information that the city minted coins in its own name, despite being an important administrative and strategic center. This suggests that the city likely used coins from other major minting centers in its vicinity or relied heavily on barter and other payment methods within the regional economic system.

Archaeological Remains

Due to Kotiaeion being situated beneath the modern city of Kütahya, prominent and extensive archaeological remains from antiquity are unfortunately limited. However, findings from various periods have been encountered during salvage excavations and urbanization projects. Particularly, remnants of the double walls built by Byzantine Emperor Justinian I can be observed in places within the modern urban fabric. Furthermore, small-scale finds such as ceramic fragments, inscriptions, architectural elements, and gravestones from the Roman and Byzantine periods are exhibited in the Kütahya Archaeology Museum. Although the presence of ancient building layers beneath the city is known, conducting comprehensive excavation work is quite difficult due to dense modern settlement. Nevertheless, future archaeological research and urban transformation projects may bring Kotiaeion's hidden ancient heritage to light.

Today

Kotiaeion is the ancient name of Kütahya, one of Turkey's important cities today. Kütahya is a modern city located in the Inner Aegean Region, famous for its ceramic and tile art. Although the remains of the ancient city largely lie beneath the modern urban fabric, the Kütahya Archaeology Museum houses important artifacts reflecting the rich history of the city and its surroundings. The city is easily accessible by road and rail. Kütahya offers visitors the opportunity to trace the footsteps of antiquity and experience traditional Turkish handicrafts.
