Alexander the Great
Conclusion
Alexander's career marks a watershed not only in Greek history, but in the history of the entire Near East. Before Alexander, we speak of the Hellenic era (Hellas is the Greek word for Greece). After Alexander, we speak of the Hellenistic era. In the former era, Greece is more or less isolated or at least contained. The primary characteristic of the Hellenistic era is the spread of Greek culture across the entire Near East, and the mixing of Greek and Oriental currents.
Alexander also marks the end of the threat of the East. One constant theme from the 6th century to the end of the 4th is the danger posed by various eastern kingdoms, especially Persia. Alexander ended this. Even after the Roman legions came, much of the Near East continued to regard Greek culture as the highest form and the one most worth imitating.
