Ultranationalism

Ultranationalism is "extreme nationalism that promotes the interest of one state or people above all others", or simply "extreme devotion to one's own nation". When combined with the notion of national rebirth, ultranationalism is a key foundation of fascism. Some ultranationalist organisations have been designated as terrorist movements by certain nation states.
According to Janusz Bugajski, "in its most extreme or developed forms, ultra-nationalism resembles fascism, marked by a xenophobic disdain of other nations, support for authoritarian political arrangements verging on totalitarianism, and a mythical emphasis on the 'organic unity' between a charismatic leader, an organizationally amorphous movement-type party, and the nation".
Roger Griffin asserts that ultranationalism is essentially xenophobic and is known to legitimise itself "through deeply mythicized narratives of past cultural or political periods of historical greatness or of old scores to settle against alleged enemies". It can also draw on "vulgarized forms of physical anthropology, genetics, and eugenics to rationalize ideas of national superiority and destiny, of degeneracy and subhumanness".
