Later on, these villages would soon turn into cities with new people called sumerians. They would make organizations in the community like a government, called institutions. They would also create irrigation systems—the system of supplying land with water with canals, ditches, etc.— to produce extra crops.
With irrigations, it provided an opportunity for Sumerians to learn a skill in a specific kind of work and it was called specialization. An example would be artisans. They developed a skill at designing jewelry, fashioning tools, and making clothing.
