What was the first to rule Cyrus Sargon or Nebuchadnezzar?

Sargon of Akkad was the first to rule, establishing his empire around 2334 BCE, while Nebuchadnezzar II ruled much later, from 605 to 562 BCE. Sargon is often credited with creating one of the world's first empires in Mesopotamia, while Nebuchadnezzar is known for his significant contributions to the Neo-Babylonian Empire, including the Hanging Gardens of Babylon. Thus, Sargon predates Nebuchadnezzar by over a millennium.
