The Indus Valley civilization, situated between the Indus and Saraswati river valleys in modern day Pakistan, arose in the third millennium BC; and by the year 2000 BC, it encompassed a huge amount of land (roughly twice the size of Texas). It had elaborately planned cities, but it did not have things like temples or palaces or elaborate graves. It did, however, have things such as irrigated agriculture and a written language (which has yet to be deciphered).

Mohenjo Daro, which was the Indus Valley civilization's largest city, and its sister city of Harappa, were at their height around 2000 BC. These cities had large, multi-floored houses, all of which had indoor plumbing, luxurious bathrooms, and a private well (meaning they didn't have to share water with neighbors).
