How did roman conquests in europe and the mediterranean influence the culture of those regions?

Of the Indo-European tribes of European origin, the Greeks were foremost as regards both the period at which they developed an advanced culture and their importance in further evolution. The Greeks emerged in the course of the 2nd millennium bce through the superimposition of a branch of the Indo-Europeans on the population of the Mediterranean region during the great migrations of nations that started in the region of the lower Danube. From 1800 bce onward the first early Greeks reached their later areas of settlement between the Ionian and the Aegean seas. The fusion of these earliest Greek-speaking people with their predecessors produced the civilization known as Mycenaean. They penetrated to the sea into the Aegean region and via Crete (approximately 1400 bce) reached Rhodes and even Cyprus and the shores of Anatolia. From 1200 bce onward the Dorians followed from Epirus. They occupied principally parts of the Peloponnese (Sparta and Argolis) and also Crete. Their migration was followed by the Dark Ages—two centuries of chaotic movements of tribes in Greece—at the end of which (c. 900 bce) the distribution of the Greek mainland among the various tribes was on the whole completed.
