How did the Greeks treat their neighbors?

The Greeks were not the most peaceful people on the planet. In ancient times, the Greeks were not a single state. These were long-term and short-term alliances of the Greek city-states. The Spartans did not hesitate to plunder and enslave the cities adjacent to them. Other cities did the same. In external relations, the Greeks are known for their trade. The objects of their culture are still found in the Mediterranean and on the shores of the Black Sea. It is known that Archimedes himself studied for a long time at the Library of Alexandria (Egypt). In ancient times, the Greeks attacked Troy. Greek myths describe this. The Greeks were forced to fight the Persians and Romans. But these wars were defensive in nature.
