Final answer:
Rich agricultural land being limited led to intense competition and conflicts, with the resultant need for strong state organization to manage resources and integrate the conquered as a lower class, as seen in the history of the Aztec empire.
Step-by-step explanation:
Since rich agricultural land was limited by isolated areas with dense populations generated intense competition among rival groups, which led to repeated conflicts. A strong and highly organized state was a definite advantage in such a competition. Losers often couldn't flee to new lands, so they were assimilated into the winner's society as a lower class. The limited availability of fertile lands often led to the development of a strong state to manage resources, defend against and wage wars, and ensure the assimilation of conquered peoples.
Throughout history, such conditions have led to the establishment of elaborate political organizations, from chiefdoms to highly stratified state societies. The growth of these societies was spurred not only by integrative pressures, such as population growth and trade, but also by conflict pressures associated with managing both external threats and internal social stratification.
The Aztec empire, for example, arose from both integrative pressures, such as agricultural surplus and trade, and conflict pressures, exemplified by the necessity to build up military might and engage in conquests. This centralization of power and creation of hierarchical social structures are hallmarks of state development.
