A king is murdered, a throne becomes a prize, and the world’s biggest empire has to prove it can still hold together. We pull away from the Peloponnesian War just long enough to track the Persian succession shocks that set the stage for Persia’s return to Greek politics, starting with the assassination of Xerxes and the hard-won rise of Artaxerxes I. Along the way, we sort Babylonian cuneiform evidence from Greek accounts packed with intrigue, and we ask what those contradictions tell us about propaganda, perspective, and how ancient history gets written.

From there, we follow the early tests of Artaxerxes’ rule, especially the Egyptian revolt led by Inaros and the disastrous Athenian intervention in the Nile Delta. It’s a sharp reminder that the Achaemenid Empire is not just a backdrop to Greek history: it has its own internal pressures, powerful nobles, and regional flashpoints that can either drain imperial attention or force rapid adaptation.

The story then turns to the chaotic handover after Artaxerxes’ death and the violent climb of Darius II. Once stability returns, Persia pivots west with a smarter approach than invasion: leverage. We dig into how Persian objectives in Asia Minor shape support for Sparta, why Tissaphernes and Pharnabazus pursue different strategies, and how later decisions, including the rise of Cyrus the Younger, help set up the flow of Persian silver that changes the naval war against Athens.
