King Nebuchadnezzar was the Ruler of Babylon in the Biblical Times and one of the most evil leaders of all time. He was an idol worshipper. He even took over every other kingdom of the time. He took the citizens of those countries as slaves and killed many others, including leaders. He was best known for building a golden image of himself and throwing the three Hebrew boys Shadrach, Meshach, and Abendego into the fiery furnace. However, they did not burn and Nebuchadnezzar had commented that he saw four men walking in the flames and one looked like a son of God (in fact, that one was an angel of God). He then made a decree that stated that eveyone must worship and obey the Hebrew boys' God. In Daniel 4, it describes how he took credit for something that belonged to God, and was driven to a feral state. He then acknowledged the God of Heaven, and now worshipped Him and turned good.
