how did the formation of nation states nd economic development redefine international relations?
Answers
A nation state (or nation-state) in the most specific sense is a country where a distinct cultural or ethnic group (a "nation" or "people") inhabits a territory and have formed a state (often a sovereign state) that they predominantly govern. It is a more precise term than "country," but of the same general meaning, being that it is an ethnic nation with its own land (thus "homeland") and government.
A nation, in the sense of a common ethnicity, may include a diaspora or refugees who live outside the nation-state; some nations of this sense do not have a state where that ethnicity predominates. In a more general sense, a nation-state is simply a large, politically sovereign country or administrative territory. A nation-state may be contrasted with:
A multinational state, where no one ethnic group dominates (may also be considered a multicultural state depending on the degree of cultural assimilation of various groups).A city-state which is both smaller than a "nation" in the sense of "large sovereign country" and which may or may not be dominated by all or part of a single "nation" in the sense of a common ethnicity.
