What were the major Sumerian cities and how did they interact with each other?

The Sumerian civilization was one of the earliest civilizations in the world, and its cities were some of the most advanced of their time. The major Sumerian cities were Uruk, Ur, Eridu, Nippur, Lagash, Kish, and Larsa. Each of these cities had its own unique characteristics, but they all shared a common culture, language, and religion.

The Sumerian cities interacted with each other through trade, diplomacy, and war. The city-states formed alliances and sometimes went to war with each other, which was a common occurrence in the region. They also traded goods such as grain, textiles, and metals. This trade was facilitated by the Sumerians' use of the wheel, which allowed for the transportation of goods over long distances.

The Sumerians were also known for their impressive architecture, including monumental temples and palaces. The city-states competed with each other to build the most impressive structures, and this competition spurred innovation and technological advances. The city-states were also home to skilled craftsmen, who produced pottery, metalwork, and other goods that were traded throughout the region.
