The Indus Valley Civilization (the Harappan Civilization or the Indus Civilization or the Indus River Valley Civilization) is one of the earliest civilizations in the world. The civilization flourished around the Indus River basin and its tributaries consisting of present day Pakistan and northwest India. In India the largest Harappan site is located in Haryana Rakhigarhi, and the second largest is in Dholavira, Gujarat. Construction of well-planned cities by using bricks, and proper drainage system are the main features of this civilization. At the time of its height, the Indus Valley Civilization geographically extended to Egypt or Mesopotamia. On the basis of archaeological research and radio carbon dating, origin of the Indus Valley Civilization lies between 3300 – 1300 BCE. Though people used to live on the banks of the Indus River before this period but it was only during a Bronze Age when they actually started living as civilized and urban societies. Harappa and Mohenjo-daro were the two prominent cities of Indus Valley Civilization.

The towns used to have great baths. Though the exact purpose of baths is not clear but it is believed that these might be used for religious bathing.
Brick lined sewers is another very prominent feature of the Indus Valley Civilization. Mohenjo-daro is the most prominent of all cities of the civilization with respect to sewerage system. Bricks used in construction were built in the ratio of 4:2:1 having 11 inches length, 5.5 inches width and 2.75 inches depth.

Engineering skills were at its heights and it is clear from the construction of docks especially at Lothal.
Wheels used in Haprappa were axeless.
Roads especially in Mohenjo-daro were as wide as 10.5 mt. Harappa also had wider roads having width of 30 foot.
Similarities between the Indus Valley Civilization and the Egyptian River Valley Civilization have been noticed by the scholars. First of all both the civilizations were dependent upon river system and flourished around the Indus and the Nile rivers respectively. It has also been found out that both of these civilizations had almost similar lifestyle and customs.
Limestone and steatite were the most common materials used to make stone sculpture in Harappa.
Information about rituals and beliefs of the Indus Valley Civilization is limited at present. But according to studies it is clear that people living in this civilization used to worship deities especially fertility deities. Religious activities were performed by priests. Ritualistic baths were part of Harappan Civilization. On some of the seals there are pictures of people doing meditation and sitting in a crossed legged posture.
Also there is very less information about the language used in the Indus Valley Civilization but some scholars believe its closeness to Vedic scripts.
Reason of Indus Valley Civilization decline
Major reason given by scholars regarding the decline of the Indus Valley Civilization was a shift in the course of river and natural disasters such as drought, flood etc. Also there was decline in the trade with Egypt and Mesopotamia. Some of the scholars also believe that wars with the Aryan Civilization may also be the reason of their decline.
