Common themes among fascist movements include: authoritarianism, nationalism (including racial nationalism), hierarchy and elitism, and militarism. Other aspects of fascism such as its "myth of decadence", anti-egalitarianism and totalitarianism can be seen to originate from these ideas. Roger Griffin has proposed that fascism is a synthesis of totalitarianism and ultranationalism sacralized through a myth of national rebirth and regeneration, which he terms "Palingenetic ultranationalism".
