Questions about the Hellenistic period should be about historical events in the wider Greek speaking world during the era. Strictly speaking questions about Alexander the Great belong to the immediately prior period of Greek history, Classical Greece, but Alexander is more relevant to the Hellenistic than the Classical period.

The Wikipedia article on the period is fairly thorough, please read it before you ask a question about the era.
