Final answer:
The collapse of these civilizations or regimes can be attributed to factors such as invasion or military conquest, gradual acquisition of power by new groups, and environmental catastrophes.
Step-by-step explanation:
Factors contributing to the collapse of these civilizations or regimes:
- **Destruction by invasion or military conquest:** Invasions by external forces, such as the Assyrians invading the Kingdom of Israel, or the Sea Peoples attacking Mycenaean Greece, led to the downfall of these civilizations.
- **Gradual acquisition of power by new groups:** In the case of Middle Kingdom Egypt, the collapse was the result of power shifts within Egypt, where new groups like the Hyksos seized control.
- **Environmental catastrophe:** Natural disasters like droughts and famine, such as the Bronze Age Collapse that affected multiple civilizations including Mycenaean Greece and the Neo-Assyrians, played a significant role in their collapse.
