Give an account of the division of the kingdom of Isreal. what unwise policies of Solomon led to it?

After the death of Solomon, Rehoboam went to Schechem for his
coronation. At this time, Northern Israel was under the leadership of Jeroboam
who came and said to Rehoboam, “your father made our yoke heavy.
Therefore, lighten the hard service of your father and we will serve you”.
Rehoboam requested that they should give him three days and come back
thereafter. Rehoboam took counsel with his father’s advisers who told him to
hearken to the people’s request, but he did not take to the advice of the
elders. Rather he listened to the advice of his age mates who advised him to
even increase the burden of the people.

Jeroboam and all the people of Israel came to Rehoboam on the
third day and the king spoke to them according to the counsel of the young men.
Israel then reacted, “What portion have we in David? We have no
inheritance in the son of Jesse, to your tents O Israel.” Israel then
departed to their tents and Rehoboam reigned over Judah. 

Solomon’s unwise
policies which led to the division of the kingdom were: 

• Solomon’s
  imposition of heavy tax 
• Solomon’s introduction of hard labour 
• Solomon’s marriage to foreign women and their gods.
