The book of Daniel follows after Ezekiel in the Old Testament. Daniel was a prophet during the early part of the captivity of the Jews in Babylon. (His Babylonian name, given to him by King Nebuchadnezzar, was Belteshazzar.)
The first half of the Book of Daniel tells the story of Daniel and three friends, and then Daniel’s rise to prominence under Kings Nebuchadnezzar, Belshazzar, and Darius. The second half is prophecy.
In the internal sense of the Word, Daniel represents the Lord at his advent. Daniel's captivity, and the actions of the Babylonian kings that he interacts with, show the state of the Israelitish church at that time.
