Final answer:
Jeroboam built two sanctuaries at Bethel and Dan in the northern kingdom of Israel, reflecting the cosmopolitan and polytheistic tendencies of the region.
Step-by-step explanation:
In the north, Jeroboam built two sanctuaries at Bethel and Dan. This occurred after the death of Solomon when the Kingdom of Israel split into two: Israel in the north and Judah in the south. Jeroboam, the first king of the Northern Kingdom, established these two sanctuaries as centers of worship in an effort to prevent the citizens of the northern kingdom from going to the temple in Jerusalem, which remained the capital of the southern kingdom, Judah. The creation of these high places is a reflection of the more cosmopolitan and sometimes polytheistic tendencies of the northern kingdom, as opposed to the more conservative, monotheistic Judah where the Prophetic Movement emerged and worship was centered on the Temple of Jerusalem.
