Explanation:

In the first half of the first millennium BCE, ancient Greek city-states, most of which were maritime powers, began to look beyond Greece for land and resources, and so they founded colonies across the Mediterranean. Trade contacts were usually the first steps in the colonization process and then, later, once local populations were subdued or included within the colony, cities were established. These could have varying degrees of contact with the homeland, but most became fully independent city-states, sometimes very Greek in character, in other cases culturally closer to the indigenous peoples they neighboured and included within their citizenry. One of the most important consequences of this process, in broad terms, was that the movement of goods, people, art, and ideas in this period spread the Greek way of life far and wide to Spain, France, Italy, the Adriatic, the Black Sea, and North Africa. In total then, the Greeks established some 500 colonies which involved up to 60,000 Greek citizen colonists, so that by 500 BCE these new territories would eventually account for 40% of all Greeks in the Hellenic World.
