A national myth is an inspiring narrative or anecdote about a nation's past. Such myths often serve as an important national symbol and affirm a set of national values. A national myth may sometimes take the form of a national epic or be incorporated into a civil religion. A group of related myths about a nation may be referred to as the national mythos, from , the original Greek word for "myth".
A national myth is a legend or fictionalized narrative which has been elevated to a serious mythological, symbolic, and esteemed level so as to be true to the nation. It might simply over-dramatize true incidents, omit important historical details, or add details for which there is no evidence; or it might simply be a fictional story that no one takes to be true literally, but contains a symbolic meaning for the nation. The national folklore of many nations includes a founding myth, which may involve a struggle against colonialism or a war of independence. In many cases, the meaning of the national myth is disputed among different parts of the population.
National myths serve many social and political purposes. National myths often exist only for the purpose of state-sponsored propaganda. In totalitarian dictatorships, the leader might be given, for example, a mythical supernatural life history in order to make him or her seem god-like and supra-powerful (see also cult of personality). However, national myths exist in every society. In liberal regimes they can serve the purpose of inspiring civic virtue and self-sacrifice, or of consolidating the power of dominant groups and legitimizing their rule.
The concept of national identity is inescapably connected with myths. A complex of myths is at the core of every ethnic identity. Some scholars believe that national identities, supported by invented histories, were constructed only after national movements and national ideologies emerged.
All modern national identities were preceded by nationalist movements. Although the term "nation" was used in the Middle Ages, it had totally different meaning than in the age of nationalism, during which it was linked to efforts aimed at creating nation-states.
Besides their social background, nationalist myths have also a psychological explanation which is connected with the nationalist myth of a stable homeland community. The complexity of relations within the modern external world and the incoherence of one's inner psychological world can result in anxiety which is reduced by static self-labeling and self-construction and gaining an imaginary emotion of stability.
Traditional myth-making often depended on literary story-tellers - especially epic poets. Ancient Hellenic culture adopted Homer's Ionian Iliad as a justification of its theoretical unity, and Virgil (70 - 19 BCE) composed the Aeneid in support of the political renewal and reunification of the Roman world after lengthy civil wars. Generations of medieval writers (in poetry and prose) contributed to the Arthurian Matter of Britain, developing what became a focus for English nationalism by adopting British Celtic material. Camões(c. 1524 - 1580) composed in Macao the Lusiads as a national poetic epic for Portugal; Voltaire attempted a similar work for French mythologised history in the Henriade (1723). Wagnerian opera came to foster German national enthusiasm.
Modern purveyors of national mythologies have tended to pension off the poets and often appeal to the people more directly through telling phraseology in media. French pamphleteers spread the ideas of Liberty, Equality and Fraternity in the 1790s, and American journalists, politicians, and scholars popularized mythic tropes like "Manifest Destiny", "the Frontier", or the "Arsenal of Democracy". Socialists advocating ideas like the dictatorship of the proletariat have promoted catchy nation-promoting slogans such as "Socialism with Chinese characteristics" and "Kim Il-sung thought".
Two of nationalism's primary myths are connected with beliefs in:
Nationalist myths sometimes tend to stimulate conflicts between nations, to magnify distinctive characteristics of the national group and to overstate the threat to the nation posed by other groups propagating militant fulfillment of their goals.
Shnirelman (1995) considers nationalist myths ... created by national intellectuals and propagated by the intelligentsia with the aim of using this myths as an instrument of ethno-political mobilization under interethnic conflicts.
Myth is inextricably linked with the concept of national identity
The core of the ethnic identity is the "myth-symbol complex" -- the combination of myths,...
We can, for example, certainly encounter term "nation" in the Middle Ages, but the word meant something completely different than in the age of nationalism, where it is inextricably linked with the efforts to create an associated state.
The nationalist myth of permanent, fixed, homeland community, derives its emotional power, according to psychoanalysis, from the anxieties generated by the fragility of the sense of self, the ego, in the face of both the complex ambiguities inherent in relationships with the external modern world, and also of the disintegrative incoherence of the inner, psychological world. In an attempt to escape the resultant anxiety, the individual engages in an act of self-labelling and self-construction which is essentially static, inserting him or herself into the institutions of society, so as to 'seek out a name' and thence attain an imaginary sense of stability [...].
[...] a North Korean's conversation is full of phrases such as 'Kim Il-sung thought', 'Kim Il-sungism', 'dedication to Kim Il-sung' and 'the Great Leader Kim Il-sung'.
... we do argue that tendency to breed conflicts is inherent to typical nationalist myths
overemphasize the cultural and historical distinctiveness of the national group [and its territory], exaggerate the threat posed to the nation by other groups, ignore the degree to which the nation's own actions provoked such treats, and play down the cost of seeking national goals through militant means.
