Beginning in the late 18th century, particularly with the French Revolution and the spread of the principle of popular sovereignty or self determination, the idea that "the people" should rule is developed by political theorists.[10] Three main theories have been used to explain the emergence of nationalism:
Primordialism developed alongside nationalism during the Romantic era and held that there have always been nations. This view has since been rejected by most scholars,[11] who view nations as socially constructed and historically contingent.[12][9] Perennialism, a softer version of primordialism which accepts that nations are modern phenomena but with long historical roots, is subject to academic debate.[13]
Modernization theory, currently the most commonly accepted theory of nationalism,[14] adopts a constructivist approach and proposes that nationalism emerged due to processes of modernization, such as industrialization, urbanization, and mass education, which made national consciousness possible.[12][15] Proponents of this theory describe nations as "imagined communities" and nationalism as an "invented tradition" in which shared sentiment provides a form of collective identity and binds individuals together in political solidarity.[12][16][17]
Ethnosymbolism explains nationalism as a product of symbols, myths, and traditions, and is associated with the work of Anthony D. Smith.[10]
The moral value of nationalism, the relationship between nationalism and patriotism, and the compatibility of nationalism and cosmopolitanism are all subjects of philosophical debate.[12] Nationalism can be combined with diverse political goals and ideologies such as conservatism (national conservatism and right-wing populism) or socialism (left-wing nationalism).[18][19][20][21] In practice, nationalism is seen as positive or negative depending on its ideology and outcomes. Nationalism has been a feature of movements for freedom and justice,[22] has been associated with cultural revivals,[23] and encourages pride in national achievements.[24] It has also been used to legitimize racial, ethnic, and religious divisions, suppress or attack minorities, undermine human rights and democratic traditions,[12] and start wars, being frequently cited as a cause of both World Wars.[25]
