What happened at both
the cities of Babylon and
Susa?

The Neo-Babylonian Empire, like the earlier Babylonia, was short-lived. In 539 B.C., less than a century after its founding, the legendary Persian king Cyrus the Great conquered Babylon. The fall of Babylon was complete when the empire came under Persian control. Susa was one of the oldest cities in the world and part of the site is still inhabited as Shush, Khuzestan Province, Iran. Excavations have uncovered evidence of continual habitation dating back to 4395 BCE but that early community grew from an even older one dating back to c. 7000 BCE.
