What led to the rise of nation states after the decline of feudalism?

The rise of nation-states after the decline of feudalism was primarily driven by the centralization of power and the emergence of stronger monarchies. As feudal lords lost their authority, kings consolidated control over territories, fostering national identity and governance. Economic changes, including the growth of trade and the emergence of a middle class, further supported the development of centralized states. Additionally, cultural and linguistic unification helped solidify national boundaries, leading to the formation of distinct nation-states.
