History of the world
Whether in prehistoric or historic times, people always needed to be near reliable sources of potable water. Settlements developed on river banks as early as 3000 BCE in Mesopotamia, on the banks of Egypt's Nile River, in the Indus River valley, and along China's rivers. As farming developed, grain agriculture became more sophisticated and prompted a division of labour to store food between growing seasons. Labour divisions led to the rise of a leisured upper class and the development of cities, which provided the foundation for civilization. The growing complexity of human societies necessitated systems of accounting and writing.
History of Kutch
The earliest human settlements can be traced back to the Early Harappan Period of Indus valley civilization, c. 3300–2600 BCE. Several sites belonging to this civilization are discovered in Kutch. Dholavira, locally known as Kotada Timba, is one of the largest and most prominent archaeological sites in India belonging to the civilization. It is located on the Khadir island in the northern part of the Kutch. The island is surrounded by water in the monsoon season. The Dholavira site is believed to have been inhabited between 2900 BCE and 1900 BCE, declining slowly after about 2100 BCE, briefly abandoned and then reoccupied, finally by villagers among its ruins, until about 1450. Other sites include Surkotada, Desalpar Gunthli, Pabumath, Kanmer and Shikarpur. More than 60 major Harappan sites are discovered around the Rann of Kutch.
