Final answer:
The split between Israel and Judah led to the downfall of both kingdoms due to political instability, invasions, and religious conflicts.
Step-by-step explanation:
The split between Israel and Judah ultimately led to the downfall of both kingdoms due to a combination of political instability, external invasions, and religious conflicts.
After the death of Solomon, Israel split into two kingdoms, with Israel in the north and Judah in the south. The northern kingdom of Israel was larger and wealthier but often engaged in conflicts with Judah and adopted foreign religious practices, which led to societal issues.
Both Israel and Judah were eventually invaded and destroyed. Israel was conquered by the Assyrians in 722 BCE, leading to the displacement and assimilation of its people. Judah faced repeated invasions and rebellions before it was eventually destroyed by the Babylonians in 586 BCE.
