Final answer:
The fall of the Indus Valley civilization was influenced by the invasion of Persian forces, decline in trade, and domestic issues.
Step-by-step explanation:
Three factors that could have contributed to the fall of the Indus Valley civilization include the invasion by Persian forces, a decline in trade, and domestic issues.
- The invasion by Persian forces in the 6th century BCE was a significant factor in the decline of the Indus Valley civilization. The Persians conquered and ruled over the region, which led to political instability and disruption of the existing social order.
- The decline in trade was another major factor. The Indus Valley civilization was known for its thriving trade network, but as the civilization declined, trade routes were disrupted, leading to economic decline.
- Domestic issues such as social unrest, political conflicts, and economic inequality also contributed to the fall of the civilization. These issues weakened the social fabric and governance, making it difficult for the civilization to sustain itself.
