A History of Agriculture in India v1.c15.5

v1.c15.5

The Chalcolithic revolution began in Mesopotamia in the fourth millennium B.C. From this nuclear zone, it spread to Egypt and subsequently to the Indus Valley. The valleys of Tigris and Euphrates have a fertile soil. The Sumerians who settled in the deltas of these rivers had just emerged from the Neolithic stage of culture. They had splendid pottery and carried on cultivation with flint hoes. Their capital was Ur, which was subsequently destroyed by flood. To the north of Sumer was Akkad, which included the Neolithic sites of Jarmo and Hassuna, which saw the birth of agriculture. By 3000 B.C. Sumerian civilization was fully developed, and about 2385 B.C. king Sargon of Akkad conquered Sumer and unified the country.
