Greek City-States Colonize From Spain to the Black Sea
What happened
Starting in the 8th century BCE, Greek city-states sent out organized expeditions to found new, independent poleis across an enormous area, from Massalia in the west to Byzantium and colonies on the Black Sea in the east, and Naukratis in the Nile Delta. This was not casual migration. A mother city, or metropolis, selected an oikist, a founder-leader, to organize the settlers and lead the voyage. Corinth's founding of Syracuse around 733 BCE is one of the best documented cases, led by the Corinthian noble Archias, and Corinth also founded Corcyra around the same time, while Megara founded Byzantium, guarding the strait that would later carry Constantinople's name.
Why it matters
The colonies spread Greek language, religious cults, and the polis across a much larger area than mainland Greece itself. Many, especially in Sicily and southern Italy, later called Magna Graecia, grew wealthy and powerful in their own right rather than staying dependent on their mother cities. Syracuse eventually became the largest polis in the entire Greek world. Naukratis, granted to Greek traders in Egypt by Pharaoh Amasis II around 570 BCE, gave several Greek cities a shared trading foothold on the Nile and stayed the only port Greeks could use in Egypt until the Persian conquest in 525 BCE.
How we know
Herodotus describes Naukratis directly in his Histories, naming Amasis II and listing the Greek cities involved. The founding of Syracuse is dated by Thucydides to about 733 BCE in his own digression on Sicilian colonization. Archaeological remains on the island of Ortygia, including early Corinthian-style pottery, support the literary tradition that a historical oikist led the settlement.
