Corinth: The Eternal Gateway of the Greek Mainland
The History of a Strategic and Commercial Hub
-The history of Corinth is inseparably linked to its geographical position on the Isthmus, which made it, since ancient times, a unique strategic and commercial center, functioning as a natural bridge between the Peloponnese and mainland Greece.
-This position allowed it to control land passage but, more importantly, the sea routes through its two ports: Lechaeum on the Corinthian Gulf and Cenchreae on the Saronic Gulf.
-The city had been inhabited since the Neolithic era, and in Homeric times it is referred to as “affneiós” (wealthy) Ephyra, indicating its ancient prosperity deriving both from its fertile land and its dominance in trade.
-Corinth emerged as a major commercial hub of antiquity, playing the role of a “gateway” for the movement of goods, ideas, and cultures.
-Its wealth was significantly boosted by the operation of the Diolkos, an ingenious construction of the 7th or 6th century BC. It was a paved road across the Isthmus along which ships were hauled from one gulf to the other, saving the dangerous and time-consuming circumnavigation of the Peloponnese.
-The tolls collected for this passage constituted a constant and immense source of income for the city-state.
-During the 7th and 6th centuries BC, Corinth experienced its peak economic and political flourishing under the tyranny, with its most notable rulers being Cypselus (657–627 BC) and his son Periander (627–585 BC).
-The tyranny of the Cypselids coincided with the period of greatest development, during which the city founded most of its colonies and undertook monumental works, such as the famous Temple of Apollo (around 560 BC), which survives to this day. Periander was even recognized as one of the Seven Sages of antiquity.
-The economic power of Corinth was reflected in its extensive network of colonies, one of the most important in the ancient Greek world.
-Its colonies expanded mainly westward, such as Corcyra (in 733 BC) and Syracuse (in 734 BC) in Sicily, which later became one of the strongest city-states. This colonial activity ensured its dominance in trade and seafaring in the western Mediterranean.
-At the same time, Corinth became known for its high-quality Corinthian pottery, particularly the black-figure style, which dominated markets until the rise of Attic pottery.
-After the fall of the tyranny (around 550 BC), Corinth transitioned to oligarchic governance and allied with Sparta, becoming one of the founding and most significant members of the Peloponnesian League. The city participated actively in the Persian Wars, and later in the Peloponnesian War as an ally of Sparta.
-Its wealth and multicultural nature were encapsulated in the proverb “Ou pantòs pleîn es Kórinthon” (“Not everyone can sail to Corinth”), highlighting the high cost of living and the city’s cosmopolitan —and hedonistic— reputation.
-At the beginning of the Classical Period, Corinth played an important role in the Persian Wars, contributing ships to the Battle of Salamis (480 BC) and land forces to the Battle of Plataea (479 BC).
-However, after the Persian defeat, the city found itself in fierce competition with the rising naval power of Athens. Through the Delian League, Athens expanded commercially and politically, threatening Corinthian interests primarily in western Greece, leading to a series of conflicts such as the Battle of Sybota (433 BC) and the dispute over the colony of Potidaea, laying the groundwork for the great Peloponnesian War.
-Corinth was one of the main forces pressing Sparta to declare the Peloponnesian War (431–404 BC) against Athens, as it felt directly threatened at the heart of its trade routes.
-As a member of the Peloponnesian League, it supplied significant naval and military forces; at the same time, its location on the Isthmus made it a vital strategic passage for League forces.
-However, Corinth did not always follow Spartan policy, as although it shared Sparta’s oligarchic institutions, it maintained autonomy in matters of commerce and diplomacy.
-Despite the joint victory over Athens, relations between Corinth and victorious Sparta cooled due to Sparta’s hegemonic and authoritarian policies. This discontent led Corinth to turn against its former ally, joining the Corinthian War (395–387 BC).
-Corinth allied with Athens, Argos, and Thebes in a war that unfolded primarily on its own territory, with the Alliance relying on the strongly fortified Corinthian line.
-The war ended with the Peace of Antalcidas, which placed Corinth under Spartan influence and constituted a defeat for the city.
-In the 4th century BC, the rise of Macedonia permanently changed the geopolitical map of southern Greece. After the Battle of Chaeronea (338 BC), Philip II of Macedon imposed his dominance and convened the Panhellenic Congress in Corinth (337 BC).
-The city was chosen as the seat of the League of the Greeks, making it the center of Macedonian interests in the south.
-The strategic fortress of Acrocorinth was transformed into a permanent base of the Macedonian army. The phrase “frourás ophthalmós” (“the eye of the garrison”) now described Acrocorinth, which, due to its position, controlled the entrance to the Peloponnese, marking the end of Corinth’s independent political existence.
-Corinth’s strategic position on the Isthmus, which had granted it archaic glory, ultimately led to its first destruction. In 146 BC, after the Battle of Leucopetra, the Romans under General Lucius Mummius razed the city entirely and plundered it as punishment for the Achaean League’s resistance.
-Yet Corinth was triumphantly reborn. In 44 BC, Julius Caesar refounded it as a Roman colony, Colonia Laus Iulia Corinthiensis, settling it with freedmen and veterans.
-Thanks to its position, it quickly became the administrative capital of the Roman province of Achaea. A new, grand Roman-style city developed (with a new forum, theaters, and baths), becoming a cosmopolitan center famous for its wealth and multicultural character.
-During the period of Roman prosperity, Corinth became one of the most important early centers of Christianity. Around AD 50–52, the Apostle Paul visited the city during his second missionary journey.
-Due to its multiethnic population and commercial activity, the city was fertile ground for the spread of the new faith.
-Paul stayed in Corinth for 18 months and later wrote the two Epistles to the Corinthians, foundational texts of Christian theology and ethics, especially the Hymn of Love.
-A significant archaeological remnant of this period is the Bema in the Agora, an elevated platform from which Paul is believed to have preached and where he stood trial before the proconsul Gallio.
-During the early Byzantine centuries, Corinth, although suffering destruction from raids (such as by the Heruli and Goths), remained a center of strategic importance.
-To counter invasions, the Isthmus was fortified with the Hexamilion Wall, a defensive structure first built in the 5th century under Theodosius II and repaired repeatedly.
-The city became the capital of the Theme of the Peloponnese, the most important province of the Byzantine Empire in southern Greece.
-Acrocorinth remained the most important castle of the Peloponnese, serving as an administrative center and defensive stronghold against Slavic, Arab, and Norman invasions.
-After the Fourth Crusade in 1204, Corinth fell under Frankish rule. Although the local lord Leo Sgouros resisted fiercely in Acrocorinth, the fortress was eventually captured.
-Corinth became part of the Principality of Achaea and served as the key stronghold for controlling access to the Morea.
-In the following centuries, the region was at the center of conflicts among major powers of the time.
-The fortress and city passed successively into the hands of the Venetians (who expanded the fortifications) and the Ottoman Turks, as control of the Isthmus was crucial for any power seeking dominance over the Peloponnese.
-Corinth played a central role in the Greek War of Independence in 1821. Acrocorinth, although well-fortified, surrendered to the Greeks in January 1822.
-Shortly afterward, the First National Assembly of Epidaurus declared Corinth the first Provisional Capital of the newly formed Greek state, replacing Tripolitsa.
-Although the capital soon moved elsewhere due to ongoing military operations, the city's contribution to the Revolution was pivotal, and control of Acrocorinth was strategically essential for sustaining the rebellion in the Peloponnese.
-The modern city of Corinth is more recent. The old city, located in today’s Ancient Corinth area, was completely destroyed by a devastating earthquake in 1858.
-The inhabitants decided to build a new city (the present one) at a northern location, near the shores of the Corinthian Gulf.
-The greatest event in the region’s modern history was the opening of the Corinth Canal, completed in 1893, fulfilling a dream thousands of years old (since the time of Periander and Nero).
-The Canal, besides being an engineering marvel, turned the Peloponnese into an island and gave tremendous impetus to navigation and economic development in the region.
