Apoikiai

Extracted from the Wikipedia article Greek colonisation.
The Archaic expansion differed from the Iron Age migrations of the Greek Dark Ages, in that it consisted of organised direction by oikistes away from the originating metropolis rather than the simplistic movement of tribes, which characterised the aforementioned earlier migrations. Many colonies, or apoikiai (Greek: ἀποικία, transl. "home away from home"), that were founded during this period eventually evolved into strong Greek city-states, functioning independently of their metropolis.
