Fun fact for a Spartanophiles: Adolf Hitler deeply admired ancient Sparta, praising it as history's first and purest racial state. He lauded the Spartans for their strict military discipline, eugenics practices, and the subjugation of a large enslaved population.
Nazi race theorists claimed the Spartans were descendants of Nordic-Aryan conquerors. =P Less ridiculously, Hitler praised Spartan eugenics, specifically their practice of exposing weak infants to protect the strength of the state. He admired how individual citizens completely sacrificed personal life for the military goals of the collective state.
In his unpublished 1928 sequel (
Zweites Buch), Hitler noted that a tiny group of Spartans controlled hundreds of thousands of helots purely through racial superiority, viewing this dynamic as a blueprint for empire. (This shows that he was a poor student of history as well as a paranoid megalomaniac, since the Spartan 'empire' never reached beyond the Peloponnese, with the exception of about 10-12 years when they controlled - more or less - most of modern-day Greece).
In an eerie but appropriate parallel, the downfall of the Spartan 'empire' was as swift and total as the Hitlerian empire was. Less happily, Hitler's empire was much more lethal -- and there are, even now, some people (white supremacists, online extremists, and Neo-Nazi groups) who want to resurrect Hitler's Nazi empire and his hateful and harmful ideas.
Happily for the human race (if not so for specific victims of these complete and utter nutbars), these ideas have failed to grow. Thank all the gods and not-gods.
