Describe the major city of Harappa and several facts about it

One of the most fascinating yet mysterious cultures of the ancient world is the Harappan civilization. This culture existed along the Indus River in present day Pakistan. It was named after the city of Harappa which it was centered around. Harappa and the city of Mohenjo-Daro were the greatest achievements of the Indus valley civilization. These cities are well known for their impressive, organized and regular layout. Over one hundred other towns and villages also existed in this region. The Harappan people were literate and used the Dravidian language. Only part of this language has been deciphered today, leaving numerous questions about this civilization unanswered.

Some facts about this city are:

• The site of the ancient city contains the ruins of a Bronze Age fortified city, which was part of the Indus Valley Civilization centered in Sindh and the Punjab

• The city is believed to have had as many as 23,500 residents and occupied about 150 hectares (370 acres) with clay brick houses at its greatest extent during the Mature Harappan phase (2600-1900 BC), which is considered large for its time.[2][3] Per archaeological convention of naming a previously unknown civilization by its first excavated site, the Indus Valley Civilization is also called the Harappan Civilization.

• The ancient city of Harappa was heavily damaged under British rule, when bricks from the ruins were used as track ballast in the construction of the Lahore-Multan Railway. In 2005

• Distinctive seals were used, among other applications, perhaps for identification of property and shipment of goods. Although copper and bronze were in use, iron was not yet employed. "Cotton was woven and dyed for clothing; wheat, rice, and a variety of vegetables and fruits were cultivated; and a number of animals, including the humped bull, were domesticated,

The Harappan civilization experienced its height around 2500 BC and began to decline about 2000 BC. The causes of its downfall are not certain. One theory suggests that the Aryan people migrated into this area. Aryan religious texts and human remains in Mohenjo-Daro suggest that the Aryans may have violently entered the area, killing its inhabitants and burning the cities.
