Byzantium

Founded in the 7th century BCE by Megarian colonists led by Byzas, Byzantium stood out due to its strategic location at the southern entrance of the straits connecting the Black Sea and the Mediterranean. This important trade hub, enriched by fishing, especially tuna fishing, and customs duties levied on passing ships, was refounded in 330 CE by Emperor Constantine I and renamed Constantinople, becoming the capital of the Eastern Roman Empire. Today, it forms the historical core of modern Istanbul and is a UNESCO World Heritage site.

History

The foundation of Byzantium, according to legend, dates back to around 657 BCE, attributed to Greek colonists from Megara led by Byzas. The city held a unique strategic position at the southern entrance of the Bosphorus, connecting the Black Sea and the Sea of Marmara, right next to the natural harbor of the Golden Horn. This location allowed the city to quickly play a key role in maritime trade. Byzantium resisted the Persian invasion in 513 BCE, later joining the Athenian-led Delian League to fight against the Persians. Maintaining its importance throughout the Hellenistic and Roman periods, the city sustained its economic power through its control over the Straits. Its greatest transformation occurred in 330 CE when Emperor Constantine I chose it as the new capital of the Roman Empire. Renamed "Nova Roma" (New Rome) or, more commonly, Constantinople, the city served for over a millennium as the center of the Eastern Roman (Byzantine) Empire and one of the most important metropolises of the Christian world. During this period, it was adorned with massive walls, palaces, churches, and public buildings.

Geographic Location

Geographically, Byzantium is situated in a unique location at the southern tip of the Bosphorus, at the crossing point between the Sea of Marmara and the Black Sea. This strategic position granted the city the privilege of controlling maritime trade between the Mediterranean world and the Black Sea basin. Its endowment with a natural harbor called the Golden Horn allowed ships to anchor safely and commercial activities to flourish. Being surrounded by sea on three sides also offered a natural defensive advantage, while from the land, it could be protected by strong walls. In antiquity, to its northwest lay the fertile lands of Thrace, and to its south, the fish-rich waters of the Sea of Marmara. Byzantium's location made it not only a trade center but also a military and cultural bridge.

Significance in Antiquity

Byzantium's significance in antiquity largely stemmed from its geographical location. Situated on the transit route for all commercial vessels passing from the Black Sea to the Mediterranean, the city gained immense economic power through customs duties and transit fees levied on these ships. Particularly the rich tuna (orkinos) fishing in the Black Sea was a vital source of income for Byzantium's economy and significantly contributed to the city's prosperity. Politically, its control over the Straits made it an indispensable strategic point for regional powers and empires. This control provided the city with a significant advantage in diplomatic negotiations and military conflicts. Even during the Roman Empire, emperors, aware of its strategic value, continued to invest in the city's infrastructure. Ultimately, with Emperor Constantine I refounding the city in 330 CE and making it the new capital of the Roman Empire, Byzantium became not only an economic and political but also a religious center, serving as the cultural and spiritual heart of the Eastern Roman Empire.

Coinage

Examination of city records reveals clear information indicating that Byzantium was a minting city. Byzantium demonstrated its economic independence and power by minting its own silver and bronze coins in antiquity. Early coinage featured a cow and dolphin motif, symbolizing the city's strong connection to the sea and its rich fishing activities, particularly alluding to tuna fishing. These figures reflected the city's role in seafood trade and likely its importance in local mythology. In later periods, Byzantium's coinage adopted the crescent and star symbols, which are still associated with the city today. These symbols were commonly associated with the goddess Artemis in antiquity, potentially indicating the city's patron goddess or the presence of an important cult. Coinage served as a means for Byzantium to proclaim its ability to manage its own economy, its position in the trade network, and its cultural identity to the world. These coins are also significant evidence of the city's commercial activities and regional interactions.

Archaeological Remains

Numerous archaeological remains, testifying to Byzantium's rich history, are woven into the fabric of modern Istanbul today. One of the city's most well-known and still visible remains is the Ancient Hippodrome, begun by Emperor Septimius Severus and expanded by Constantine I. This colossal structure, used for chariot races and public spectacles, was central to the social and political life of the Byzantine Empire. Among the most striking artifacts surviving on the "Spina" in the center of the Hippodrome is the Serpent Column, brought from the Temple of Apollo at Delphi. Erected in commemoration of the victory against the Persians at the Battle of Plataea, this column represents the presence of the ancient Greek world in Byzantium. Furthermore, sections of the city walls, particularly the Theodosian Walls, still stand, showcasing the architectural and engineering genius of the Byzantine period. These remains prove that Byzantium was not merely a Greek colony but also a magnificent metropolis that served as the capital of an empire for a millennium.

Today

Ancient Byzantium today forms the core of the historical peninsula of Istanbul, Turkey's largest city and cultural capital. The city's ancient and Byzantine-era remains still persist amidst modern structures, offering visitors the opportunity to trace the footsteps of thousands of years of history. Sultanahmet Square and its surroundings, in particular, host Byzantine-era structures such as the Hippodrome, Hagia Sophia, and the Basilica Cistern. These areas are easily accessible by public transport and can be explored on foot. The remains of Byzantium are inscribed on the UNESCO World Heritage List and are visited by millions of local and foreign tourists each year. Modern Istanbul is a unique city where ancient heritage intertwines with contemporary life, where past and present meet.
