Who is Absalom from A Tale of Three Kings and what is their importance?

Absalom is David's son, a good, kind person who often has insight into problems. Absalom has gathered a large group of people around him who see the problems of David's kingdom in the same way as Absalom and believe Absalom should be king in David's place. Absalom listens to the opinions of his followers and soon comes to believe as they do, that he should be king. Absalom decides to lead a rebellion against his own father. Absalom wants to be king so that he can make positive changes for the kingdom, changes that David may be reluctant to do himself. David refuses to fight Absalom's take over despite the opinions of his advisers. David believes that God gave him his kingdom and that it is up to God to take it away, in the form of his son, Absalom.
