How?

The rivers gave rise to some of the early civilizations in history, the people in these civilizations were known as the Mesopotamians. The Mesopotamian Civilization began in Mesopotamia because the soil provided a surplus of food and with the surplus, you could easily settle down to village life and with these new settlements, towns and cities began to make their appearance, a process known as urbanization. With settlements and a surplus of food came an increase in the population, a well-defined division of labour, organization, cooperation and kingship. The emergence of cities involved interaction between people, most cities evolved from smaller farming villages and with the practice of irrigation, which was necessary for villages distant from the Tigris and Euphrates, a stable food supply was produced. This, in turn, allowed increases in the number of people who inhabited each settlement.
 * How did it start? **


 * How did it change over time? **

Mesopotamia did not really change over time but as each new group of people moved into the region, or took control of the government; they took in and adopted some of the culture, traditions, beliefs, and the religions of the people who had come before them. Therefore, certain aspects of civilization in Mesopotamia remained the same, and some changed over time. Mesopotamia did change with some things like as over time, the need for writing changed and the signs developed into a script we call cuneiform.


 * How did it end? **

Mesopotamia technically never did end; all societies of the era had falls and ups, really big ups and downs like being occupied by foreign for hundreds of years at a time. Power shifted from the Egyptians to the Babylonians to the Persians to the Assyrians eventually to the Romans and to no one during the dark ages, however the culture was never wiped out completely like the Incas or Mayans, and remainments still remain of the original Mesopotamian society in the modern day region.
