The Intelligenzaktion although brutal, is something found historically such as when Charles the Great wiped out the Saxon elites which then fully allowed Christianity to take over, the Roman Destruction of the Jewish Elite During the First Jewish Revolt, the Mongol Massacres of Persian Elites During the Invasion of Khwarazm, etc.
Is there anything behind the Intelligenzaktion? The document records for deaths seem to be all in order?
