Who was Nabonidus?

Nabonidus was the last king of the Neo-Babylonian Empire, ruling from 556 to 539 BCE. He is known for his unusual religious practices and preference for the moon god Sin over the traditional Babylonian god Marduk. His reign was marked by significant cultural and architectural developments, but also by political instability. Nabonidus was ultimately defeated by the Persian king Cyrus the Great, leading to the fall of Babylon.
