How did trade routes and warfare affect civilizations between 500 and 1500 ce in muslim civilization

Greece is a country surrounded by water and the sea has always played an important role in its history. The ancient Greeks were active seafarers seeking opportunities for trade and founding new independent cities at coastal sites across the Mediterranean Sea. By the seventh and sixth centuries B.C., Greek colonies and settlements stretched all the way from western Asia Minor to southern Italy, Sicily, North Africa, and even to the coasts of southern France and Spain. Regional schools of artists exhibited a rich variety of styles and preferences at this time. The major Ionian cities along the coast of Asia Minor prospered
, which was ruled by the legendary King Croesus in the sixth century B.C. Indeed, by this time, the eastern Greeks controlled much of the Aegean Sea and had established independent cities to the north along the Black Sea. This region, in particular, opened up further trade connections to the north that gave access to valuable raw materials, such as gold.
