Belshazzar

Belshazzar was appointed co-regent by his father Nabonidus, who spent much of his reign in the Arabian oasis of Tayma. Belshazzar effectively ruled Babylon from the capital, managing administration and defense.

Cyrus the Great's Persian army captured Babylon. Belshazzar, co-regent with his father Nabonidus, was killed during the conquest. This event ended Neo-Babylonian independence and incorporated it into the Achaemenid Empire.

According to the biblical Book of Daniel, during a feast, a mysterious hand wrote a prophecy on the wall of Belshazzar's palace. Daniel interpreted the writing as a divine judgment predicting Babylon's fall, which occurred that night.
