How did changing economic and social conditions wars and the growing power of monarchs begin to build the framework for the modern nation-state?

Changing economic and social conditions, such as the rise of trade and the emergence of a merchant class, shifted power dynamics away from feudal lords towards centralized authority. Wars often necessitated stronger governance and resource mobilization, leading monarchs to consolidate power and create bureaucratic states. Additionally, the growing influence of nationalism fostered a sense of shared identity among populations, further solidifying the concept of the modern nation-state. Together, these factors laid the groundwork for the development of sovereign states with defined borders and centralized governments.
