Answer:
Nationalism is the social and political movement that, within a society, stimulates the feeling of belonging to a specific culture, region and people, which citizens are proud of and want to protect at any cost.
The rise of nationalism during the period 1750-1900 owes several factors. At the beginning of this period, we can say that nationalism was born with the frequent battles that a region established to dominate another region. The battles made the citizens want to protect their territory and their people, and prevent a foreign culture from dominating what was already established.
This feeling also grew during the Napoleonic wars, where the search for the defense of territories and growing imperialism established strong nationalist principles in the population, strengthening the monarchies. The strengthening of monarchies encouraged groups opposed to this type of government. These groups also encouraged nationalist concepts, adopting enlightened ideas and claiming that the people, the nation, were sovereign.
This nationalist sentiment stimulated the struggle for the fall of monarchies and the independence of colonies, generating a strong feeling of belonging and patriotism.
Following these concepts, nationalism has been strengthened over the years, becoming a political ideology and being one of the main reasons for the establishment of authoritarian nationalist governments, which encouraged several wars, with the discourse of maintaining the honor and power of their nation.
