What group of people reject the idea of the Sumerian city state?

The group that tends to reject the idea of the Sumerian city-state concept mainly includes certain revisionist historians and archaeologists who argue that the traditional view oversimplifies the complexity of early Mesopotamian societies. They suggest that instead of distinct city-states, there may have been more fluid and interconnected social structures that encompassed various forms of governance. This perspective emphasizes a more nuanced understanding of urban development and political organization in ancient Sumer.
