According to the author of the book of Chronicles, when Abijah died, his son Asa became the king, and for ten years, everything was peaceful and calm in the land. This means that people had a good and quiet life during Asa's early time as king.
2 Chronicles 14:1: So Abijah slept with his fathers, and they buried him in the city of David: and Asa his son reigned in his stead. In his days the land was quiet ten years.
This verse states that there was war between Rehoboam and Jeroboam all the days of his life, suggesting continuous conflict rather than peace.
1 Kings 15:6: And there was war between Rehoboam and Jeroboam all the days of his life.
