The Indus Valley Civilization, which thrived from approximately 3300 to 1300 BCE, declined around 1900 BCE due to a combination of factors. Environmental changes, such as shifts in monsoon patterns and possible droughts, may have impacted agriculture and water supply. Additionally, there is evidence of social upheaval and possibly invasions by nomadic groups. By around 1300 BCE, the civilization had largely disintegrated, leading to the emergence of smaller, regional cultures.
