2 Chronicles contains the story of the kings of Israel. It discusses the 400 years after King David. It is in the Old Testament of the Bible.
2 Chronicles describes the great temple (house of God) that Solomon built in Jerusalem. This building was a great work for God. The temple was a very beautiful building. And the priests and people came to the temple to pray.
After Solomon died, his country divided into two countries. 2 Chronicles describes the kings of both these countries and their work. Some of these kings were good kings, who served God. But most of these kings were very evil. They did not obey God's law. They served false gods. And these kings were cruel to the people. So, God allowed the enemies of these two countries to attack. And the enemies destroyed both countries.
