Early influences that shaped the ideology of fascism have been dated back to Ancient Greece. The political culture of ancient Greece and specifically the ancient Greek city state of Sparta under Lycurgus, with its emphasis on militarism and racial purity, were admired by the Nazis. Nazi "Führer" Adolf Hitler emphasized that Germany should adhere to Hellenic values and culture – particularly that of ancient Sparta. He rebuked potential criticism of Hellenic values being non-German by emphasizing the common Aryan race connection with ancient Greeks, saying in "Mein Kampf": "One must not allow the differences of the individual races to tear up the greater racial community".
