What was created in Europe when lords/kings centralized their military power?

Nation-States

Explanation:

The process of centralizing the king's military power took place at the end of feudalism and was the great symbol of the formation of European nation-states, mainly Spain, Portugal and France, which were the first to adopt this system and establish the king's political control over a territory. This process was considered very modern, ending feudalism and giving space for new forms of governance to stabilize.
