The Indus River Valley period, characterized by the flourishing of the Harappan civilization, is generally considered to have ended around 1900 BCE. The decline is attributed to a combination of factors, including climate change leading to drought, shifts in river patterns, and possibly social upheaval or invasions. These changes resulted in the gradual abandonment of urban centers and a decline in trade and agricultural productivity. Ultimately, the civilization fragmented into smaller, less organized communities.
The Harrpan civilization collapsed about 1500 B.C. Historians think that several earthquakes and floods damaged the cities. Then the Indus River changed its course, killing many people and forcing others to flee the area.

The Huang He (Yellow River) civilization, also known as Chinese civilization, did not end in a single event but rather evolved over millennia through various dynastic changes, cultural shifts, and external pressures. Major factors contributing to its transformation included invasions by nomadic tribes, internal strife, and natural disasters such as floods and droughts. The rise of new dynasties, like the Qin and Han, marked significant shifts in governance and culture, leading to the continuous development of Chinese civilization. Ultimately, the civilization adapted and persisted, transitioning through different historical phases rather than experiencing a definitive end.

The Indus Valley Civilization declined around 1900 BCE due to a combination of factors such as environmental changes, natural disasters, and possibly invasions or conflicts. The drying up of the Saraswati River and changes in trade routes may have also contributed to the civilization's downfall.
the above is answer is not at all correct. its true that aryans came in 1500bc and they were very destructive in nature not like indus valley civilization who were always had constructive minds. the indus valley civilization existed from 2500bc to 1750 bc. that means before aryans came the indus valley civilization was already finished 250 years ago. there are some historians that say that the indus river was flooded and due to that the indus valley civilization came to an end but in reality it was not possible that a flood destroys the whole civilization which was extended from uttar pradesh in the west to jammu and kashmir in north and to maharashtra in west. the actual reason which is more relaible answer than any other is that the indus valley civilization got extinct due to ecological factors. environmental and climatic factors like drying up of rivers,deforestation,soil sanity etc led to the decline of the greatest civilization.
