The Indus civilization

The Indus civilization is one of the huge missing civilizations spread across an area where Pakistan and Western India are now. It is one of the most important ancient civilizations. But few people know about them, mainly because no one has deciphered their language. People have built more than a hundred towns and villages, including Harappa and Mohenjo-Daro cities. Each area has a sewage drainage system and a private sanitary system. It seems that this civilization has no class and no excellent army in the field of astronomy and agriculture. This is also the first civilization to produce clothes with a cotton cloth. This civilization disappeared 4,500 years ago and no one knew about it until the ruin was excavated in the 1920s. Some theories try to explain this disappearance, such as the changes in their environment as dry as the Ghaggar Hakra river, and the temperature is colder and drier. Another hypothesis is that the Aryans invaded the area around 1500 BC.

Indus civilization, also known as the Harappan civilization, is one of the biggest civilizations in ancient history, stretching to the regions of India, Pakistan, and Afghanistan and up to five million people. At the peak period, this civilization is proud to have some of the most impressive architecture in the world, among other achievements. A hypothesis is that it is a victim of climate change that leads to drought and hunger. This is an indispensable civilization in the list of mysteriously lost civilized that once existed.
