Greek city-states began establishing
colonies along the
Black Sea coast of
Crimea in the 7th or 6th century BCE. Several colonies were established in the vicinity of the
Kerch Strait, then known as the Cimmerian Bosporus. The density of colonies around the Cimmerian Bosporus was unusual for Greek colonization and reflected the importance of the area. The majority of these colonies were established by
Ionians from the city of
Miletus in
Asia Minor.
