Final answer:
Leaders are necessary as populations expand due to the need for greater coordination, maintenance of order, and decision-making.
Step-by-step explanation:
Leaders are necessary as populations expand due to several reasons:
- Greater coordination: As the population increases, there is a need for greater coordination to satisfy the needs of the growing population. This includes managing agricultural production, infrastructure, and trade. Leaders play a crucial role in organizing complex systems and ensuring economic growth.
- Maintenance of order: In larger civilizations, leaders possess the authority to command the obedience of subjects, enforcing order and peace. They provide protection and prosperity in exchange for resources and taxes. This reinforces social hierarchy and specialization of labor.
- Decision-making: As populations grow, decisions about war, migration, and other important matters become more complex. Leaders provide guidance and make decisions on behalf of the population, considering the overall well-being of the community.
