Attacks posed a significant problem for the Sumerians due to their city-state structure, which often left them vulnerable to invasions from neighboring groups seeking resources or territory. The lack of a unified central authority meant that individual city-states had to fend for themselves, making them prone to conflict and instability. Additionally, their reliance on agriculture and trade made them attractive targets for marauders. As a result, the constant threat of attacks hindered Sumerian development and required ongoing military and defensive efforts.
