Historical Period: 'Persia from Cyrus II to the death of Darius III'? (1 Viewer)

[Fake-Name]

Hey, I'm looking to purchase/download/find some extra material for my historical period Persia from Cyrus II to the death of Darius III. I'm just wondering, what will the topic be focused on? I'm guessing its the building of the Persian empire and 'ancient imperialism' since that's what the achaemenid is best known for, but is there anything else?

The BOS syllabus gives nothing away.

Thanks.
