As early as the 7th century BC, where did the Athenians emigrate?

As early as the 7th century BC, the Athenians migrated to Signon in the northwest corner of Asia Minor and Ereos in Thrace, and by the 6th century BC, they had firmly controlled these two areas. At the same time, the Black Sea coast has also become its commodity market and the supplier of grain and raw materials. Overseas interests are becoming more and more important to the rapidly developing Athens.
