Nabonidus

Last king of the Assyrian for Neo-Babylonian Empire (r. 556–539 BC)

Nabonidus was the last king of the Neo-Babylonian Empire, ruling from 556 BC to the fall of Babylon to the Achaemenian Empire under Cyrus the Great in 539 BC. Nabonidus was the last native ruler of ancient Mesopotamia, the end of his reign marking the end of thousands of years of Sumero-Akkadian states, kingdoms and empires. He was also the last independent king of Babylon. Regarded as one of the most vibrant and individualistic rulers of his time, Nabonidus is characterised by some scholars as an unorthodox religious reformer and as the first archaeologist.
