Hiya, just FYI, there are a couple of previous answers worth checking out -
/u/Daeres in Who populated the cities founded by Alexander the Great?
/u/Iphikrates in Alexander the Great founded dozens of cities and towns over his life. How was a town just "founded?" (which includes links to a couple more), and with more related discussion in Greek cities founded colonies throughout the Mediterranean and the Black Sea, but did these colonies have any obligations, be they political, economic or military, to their founders?
