Susa

Background

Susa underwent a major political and ethnocultural transition when it became part of the Persian Achaemenid empire between 540 and 539 BCE when it was captured by Cyrus the Great during his conquest of Elam (Susiana), of which Susa was the capital. The Nabonidus Chronicle records that, prior to the battle(s), Nabonidus had ordered cult statues from outlying Babylonian cities to be brought into the capital, suggesting that the conflict over Susa had begun possibly in the winter of 540 BCE.

It is probable that Cyrus negotiated with the Babylonian generals to obtain a compromise on their part and therefore avoid an armed confrontation. Nabonidus was staying in the city at the time and soon fled to the capital, Babylon, which he had not visited in years.[69] Cyrus' conquest of Susa and the rest of Babylonia commenced a fundamental shift, bringing Susa under Persian control for the first time.

Under Cyrus' son Cambyses II, Susa became a center of political power as one of four capitals of the Achaemenid Persian empire, while reducing the significance of Pasargadae as the capital of Persis. Following Cambyses' brief rule, Darius the Great began a major building program in Susa and Persepolis, which included building a large palace. During this time he describes his new capital in the DSf inscription:

"This palace which I built at Susa, from afar its ornamentation was brought. Downward the earth was dug, until I reached rock in the earth. When the excavation had been made, then rubble was packed down, some 40 cubits in depth, another part 20 cubits in depth. On that rubble the palace was constructed."[70] Susa continued as a winter capital and residence for Achaemenid kings succeeding Darius the Great, Xerxes I, and their successors.
