Why do you think the effects of Hellenistic culture were so longlasting?

They focused on arts and learning which has a long life.

      The word Hellenistic comes from the root word Hellas, which was the ancient Greek word for Greece. The Hellenic Age was the time when Greek culture was pure and unaffected by other cultures. The Hellenistic Age was a time when Greeks came in contact with outside people and their Hellenic, classic culture blended with cultures from Asia and Africa to create a blended  culture. One man, Alexander, King of Macedonia, a Greek-speaker, is responsible for this blending of cultures.

To understand how the Kingdom of Macedonia dominated the Greek world, we need to first take a look at the Battle of Leuctra in 371 BC, between Sparta and Thebes. As you read in the last chapter, Sparta defeated Athens in 404 BC, ending the Peloponnesian War. Though Sparta was victorious, it was also weakened by this war. Thebes, an ally of Sparta during the Peloponnesian War, became powerful after the conflict. Sparta and Thebes went to war over territory close to Thebes. The battle took place in Boeotia, near the city-state of Leuctra in July 371 BC.

Explanation:     Epaminondas, the Theban general, introduced a new fighting technique at Leuctra. As you remember, the Greeks fought in a phalanx, a solid block of men. The best men would form on the right side, or weak side, as a place of honor. The Spartan phalanx at Leuctra was twelve men deep. In the traditional formation, the best soldiers of one army would always face the weakest of the other. Epaminondas placed his best soldiers on the left, guaranteeing that they would face the best Spartans. He also took no chances, forming his left side 50-men deep.  Epaminondas held the Theban right-side back, refusing to fight the Spartan left. The Theban left of 50-men deep pushed the Spartan right, trampling men and killing the Spartan king. Sparta was not used to losing battles. Sparta would go on, but this was the end of Sparta as the dominant Greek city-state, and the end of its control over most of the Peloponnese.
