Nebuchadnezzar - King of Babylon

Nebuchadnezzar II was the Babylonian King who conquered the nation of Judah which ended the reign of Jewish Kings and forced the Jews back into slavery. In the Bible, Nebuchadnezzar is mostly known by his dealings with Daniel, the prophet, and Daniel's friends: Shadrach, Meschach and Abednego. 

External sources say that Nebuchadnezzar was the son of Nabopolassar who set up the Neo-Babylonian Empire as the days of the Assyrian Empire came to an end.
