Who ruled the ten northern tribes after the kingdom split?

After the kingdom split, the ten northern tribes of Israel were ruled by Jeroboam I, a former servant of King Solomon. He established the northern kingdom, known as Israel, around 931 BCE, and set up its capital in Shechem. To prevent his subjects from returning to Jerusalem for worship, he instituted golden calf idols in Bethel and Dan as alternative sites of worship. This marked the beginning of a distinct political and religious identity for the northern tribes.
