The history of fascist ideology is long and it also involves many sources. Fascists took inspiration from sources as ancient as the Spartans for their focus on racial purity and their emphasis on rule by an elite minority. Fascism has also been connected to the ideals of Plato, though there are key differences between the two. Fascism styled itself as the ideological successor to Rome, particularly the Roman Empire. The Enlightenment-era concept of a "high and noble" Aryan culture as opposed to a "parasitic" Semitic culture was core to Nazi racial views. From the same era, Georg Wilhelm Friedrich Hegel's view on the absolute authority of the state also strongly influenced Fascist thinking. The French Revolution was a major influence insofar as the Nazis saw themselves as fighting back against many of the ideas which it brought to prominence, especially liberalism, liberal democracy and racial equality, whereas on the other hand Fascism drew heavily on the revolutionary ideal of nationalism. Common themes among fascist movements include; nationalism, hierarchy and elitism, militarism, quasi-religion, masculinity and voluntarism. Other aspects of fascism such as its "myth of decadence", anti‐egalitarianism and totalitarianism can be seen to originate from these ideas. These fundamental aspects however, can be attributed to a concept known as "Palingenetic ultranationalism", a theory proposed by Roger Griffin, that fascism is a synthesis of totalitarianism and ultranationalism sacralized through myth of national rebirth and regeneration.
