Invented traditions are cultural practices that are presented or perceived as traditional, arising from the people starting in the distant past, but which in fact are relatively recent and often even consciously invented by identifiable historical actors. The concept was highlighted in the 1983 book The Invention of Tradition, edited by Eric Hobsbawm and Terence Ranger. Hobsbawm's introduction argues that many "traditions" which "appear or claim to be old are often quite recent in origin and sometimes invented." This "invention" is distinguished from "starting" or "initiating" a tradition that does not then claim to be old. The phenomenon is particularly clear in the modern development of the nation and of nationalism, creating a national identity promoting national unity, and legitimising certain institutions or cultural practices. The concept has been applied to cultural phenomena such as the "Highland myth" in Scotland, the traditions of major religions, some Korean martial arts such as Taekwondo, and some Japanese martial arts, such as Judo. It has influenced related concepts such as Benedict Anderson's imagined communities and the pizza effect. Indeed, the sharp distinction between "tradition" and "modernity" is often itself invented. The concept is "highly relevant to that comparatively recent historical innovation, the 'nation', with its associated phenomena: nationalism, the nation-state, national symbols, histories, and the rest." Hobsbawm and Ranger remark on the "curious but understandable paradox: modern nations and all their impedimenta generally claim to be the opposite of novel, namely rooted in remotest antiquity, and the opposite of constructed, namely human communities so 'natural' as to require no definition other than self-assertion." The concept of authenticity is also often questionable. Fakelore or pseudo-folklore is inauthentic, manufactured folklore presented as if it were genuinely traditional. The term can refer to new stories or songs made up, or to folklore that is reworked and modified for modern tastes.
