Which leader constructed two golden calves for worship in the North apart from Jerusalem?

The leader who constructed two golden calves for worship in the North, separate from Jerusalem, is indeed Jeroboam.

After the division of the kingdom following Solomon's reign, Jeroboam became the first king of the northern kingdom of Israel. To prevent his subjects from traveling to Jerusalem (the capital of Judah) for worship, Jeroboam strategically created two golden calves, establishing them in the cities of Bethel and Dan. This was a significant act as it not only reflected a deviation from the centralized worship prescribed in the Law of Moses but also indicated the beginning of a distinct religious identity for the northern kingdom. This decision was intended to consolidate his power and ensure fidelity among the people, but it ultimately led to idolatry and set a precedent for future kings in Israel to adopt similar practices.

This act is critical in the narrative of the Old Testament as it symbolizes a turning point in the history of Israel, highlighting the ongoing struggles with faithfulness to Yahweh and the consequences of diverging from His commands.
