In Neolithic times, people in some areas of the world began to?

 Farming

100

One of the biggest problems was

 the uncontroled water supply 

100

Irrigation systems provided enough water for Sumerian farmers to

grow plenty of food

100

As Sumerian cities grew

they fought over the right to use more water

100

As you've seen, beginning around 3500 B.C.E., the Sumerians progressed from living in small farming villages to

building large, walled city-states

200

Some historians believe that by 5000 B.C.E.,farmers in the Zagros foothills did not have enough land to 

grow food

200

During the spring, rain and melted snow from the mountains flowed into the

Tigris and Euphrates rivers and Euphrates rivers

200

The irrigation system passed through a number of villages as it

carried water from the river to the fields

200

Disputes over water became so intense that they often

led to bloodshed

200

Food shortages had forced settlers in Mesopotamia to

move from the foothills down to the river valley

300

in the spring both of the rivers in Zagros 

 flooded so the farming ideas might work 

300

 If it happened after farmers planted their crops the young seedlings would be

washed away

300

Since villages were connected for miles around by these canals, farmers could no longer

live apart, or in small groups

300

The Sumerians looked for ways to protect their cities from

neighboring communities

300

 There, farmers faced the problem of having either

too much water or too little To control the water supply

400

the northern part was 

 was hilly and receievd rain

400

Sumerian farmers began creating irrigation systems for their

 fields

400

Gradually, villages came to depend on one another to

 build and maintain this complex irrigation system

400

There were no mountain ranges or rushing rivers to

keep out enemies Around the cities

400

so the Sumerians had to

cooperate with one another

500

The rivers overflowed onto

the plains during flood season 

500

 Sumerian farmers began creating irrigation systems for their 

supply of water 

500

As the Sumerians worked together, they began to

create larger communities.

500

The Sumerians also dug moats outside city walls to

help prevent enemies from entering their cities

500

These independent city-states often

 fought with one another
