By the late 6th century BCE, Syracuse—originally a Corinthian foundation—had grown beyond a typical colony into a dominant Sicilian Greek city-state, illustrating how Corinthian colonial ventures could generate powerful, semi-independent economic centers.
Periander dies (commonly dated c. 587 BCE). His reign is frequently treated as a high point for Corinth’s Archaic commercial and colonial policy, before later political changes and shifting interstate pressures.
Construction of the Diolkos (stone-paved haulage/portage route) begins by around 600 BCE (late 7th/early 6th century BCE). It helped Corinth monetize and control movement between the Saronic and Corinthian Gulfs, reinforcing the city’s role as a commercial crossroads.
Corinth founds Potidaea around 600 BCE on the Pallene (Kassandra) peninsula. The colony strengthened Corinthian access to northern Aegean routes and resources and later remained tied to Corinth in interstate conflicts.
Greek settlers from Corinth (and likely Corcyra) found Apollonia on the Adriatic around 600 BCE, developing a trade-oriented polis interacting closely with local Illyrian populations. The colony supported Corinthian commercial penetration of the Adriatic corridor.
Anactorium is described in ancient tradition as jointly colonized by Corinthians and Corcyraeans. Positioned at the mouth of the Ambraciot Gulf, it functioned as a strategically placed port and regional emporium tied to Corinthian interests.
Corinth founds Ambracia (near modern Arta) in the mid-7th century BCE (commonly dated to 625 BCE). The settlement extended Corinthian influence into Epirus and linked Corinth to resources and exchange networks in northwestern Greece.
After the Protocorinthian phase, Corinthian pottery production enters its main Corinthian period (c. 625–535 BCE). Continued mass export of these wares reflects Corinth’s sustained role in Archaic Mediterranean trade networks.
Settlers from Corinth and Corcyra found Epidamnus (later Dyrrhachium/Durrës) around 627 BCE on the Adriatic coast, creating a bridgehead for trade with Illyrian communities and for routes up the Adriatic.
Periander rules Corinth as the second Cypselid tyrant (traditionally c. 627–587 BCE). Ancient and modern accounts associate his reign with intensified commercial policy, infrastructural initiatives, and active colonial management.
Cypselus becomes tyrant of Corinth (c. 657–c. 628 BCE), founding the Cypselid dynasty. Under Cypselus, Corinth’s overseas interests and colonial activity in the northwest Greek world are emphasized as part of broader economic and strategic growth.
Corinth’s Protocorinthian ceramic production (c. 720–625 BCE) helped drive economic expansion: fine, widely traded wares circulated broadly across the Aegean and beyond, strengthening Corinth’s commercial reach.
Corcyra (Kerkyra/Corfu) emerges as a Corinthian colony in the Archaic period, positioned to support Adriatic sea routes and long-distance commerce—though it later became a frequent rival of its mother-city.
Greek settlers from Corinth, traditionally led by Archias, found Syracuse on Sicily’s east coast. The colony became a major western Greek polis and an important node for Corinthian trade and influence.
