You might want to have a look at this video- it shines some light on the back-story described by events in the bible! In the book of Daniel it describes the story of King Nebuchadnezzar of Babylon. Nebuchadnezzar was a great king in his day, the greatest king in history. He single handedly built a huge empire through military conquest and also the great city of Babylon- the greatest city in the world which is modern day Baghdad. He was completely full of pride and self-absorbed. He was incredibly proud of what he had accomplished. He thought he had accomplished all of this under his own strength and intelligence. He was so proud that he even inscribed his name on all of the bricks of his constructions in the city of Babylon along with boastful claims about himself.

It says in Daniel 4:30 that Nebuchadnezzar said to himself: "Is this not the great Babylon I have built as the royal residence, by my mighty power and for the glory of my majesty?

This all culminates in Nebachadnezzar receiving an angelic visitation in a dream which Daniel then interpreted, one year later it came to pass and Nebuchanezzar went completely mad and left his capitol city to live with the wild animals eating grass and his head covered in the dew of heaven. Once he repented of his pride and acknowledged the one true God his sanity was restored along with his kingdom. The link to the video is below, it is 28 minutes.
