Lesson 2: Sumer
          
The 
            first major civilization in Mesopotamia was in a region called Sumer. 
            The Sumerians were able to settle and prosper because they learned 
            how to irrigate 
            the land. By bringing water to the fields, they turned Mesopotamia 
            into a prime agricultural region. 
          The Sumerians 
            grew several kinds of crops. The most valuable one was barley, which 
            was used to make flour and bread. Dates were also very valuable to 
            the Sumerians. They were eaten once ripe or else they were dried for 
            future consumption. Dates also made an excellent wine. Date trees 
            were also an excellent source of leaves for house thatching, while 
            the wood from the trunk was used for building. Another important crop 
            was the sesame seed. It was used in baking and seasoning, but its 
            real value was as a cooking oil. Other crops were wheat, onions, cucumber 
            and other fruits and vegetables. The Sumerians also raised goats, 
            pigs, sheep, and cattle.
          Although agriculture was the chief industry of Sumer, commerce with distant lands also flourished. The Mesopotamian plain was lacking in resources such as metals, timber, stone, and grapevines, so the Sumerians had to trade abroad to get them. Initially, the Sumerians traded surplus barley for these goods. This soon became too expensive and difficult because the sacks of barley were large and heavy. As a result, the Sumerians began to manufacture trading goods that they could transport more easily, such as cloth and bronze ornaments.
          Sumer thrived for many centuries, largely because of their advanced 
            irrigation system. However , this irrigation system may have led to 
            the downfall of Sumer. The water diverted from the rivers to irrigate 
            the soil also carried harmful salts and other mineral matter. The 
            soil became more acidic and the crops started to die. Sumer lost its 
            economic strength, which in turn led to a loss of political and military 
            strength. Sumer was soon too weak to fight off invaders and was conquered.
