Improved farming led to the development of government in several ways. The development of agriculture allowed for the production of surplus crops, which could be traded for other goods. This increased trade necessitated the regulation of trade and exchange rates by government officials, leading to an expansion of the government's role over time.
Additionally, the ability to produce surplus food allowed early humans to settle in one place and build permanent structures, leading to the development of villages, towns, and eventually cities. As populations grew and cities expanded, there was a greater need for governance to manage the increasingly complex societies that were emerging¹.
In summary, improved farming led to increased trade, population growth, and urbanization, all of which necessitated the development of more complex forms of government to manage these changes.
