Step-by-step explanation:
Nationalism is an ideology and sociopolitical movement that emerged along with the modern concept of nation, typical of the Contemporary Age, in the historical circumstances of the so-called era of Revolutions (industrial revolution, bourgeois revolution, liberal revolution) and independence movements of the European colonies in America, since the end of the 18th century, it can also designate nationalist sentiment and the era of nationalism.
According to Ernest Gellner, "nationalism is a political principle that holds that there must be congruence between national unity and politics" or in other words "nationalism is a theory of political legitimacy that prescribes that ethnic boundaries should not be opposed politicians". For his part, Liah Greenfeld defines the term "nationalism" in a general sense as the "set of ideas and feelings that make up the conceptual framework of national identity," the latter considered as the "fundamental identity" in the modern world versus other identities insofar as "it is considered as defining the very essence of the individual".
