What was the history of which classical civilization was shaped by the monsoon cycle the Himalaya Mountains and the Indus River?

The classical civilization shaped by the monsoon cycle, the Himalaya Mountains, and the Indus River is the Indus Valley Civilization, which thrived around 2500 to 1900 BCE in present-day Pakistan and northwest India. The monsoon rains were crucial for agriculture, allowing for the cultivation of crops like wheat and barley, while the Indus River provided water for irrigation and trade. The geography, including the protective barrier of the Himalayas, influenced the civilization's development, facilitating a unique culture and advanced urban planning. However, climate change and shifting monsoon patterns eventually contributed to its decline.
