The concept of Zeitgeist goes back to Johann Gottfried Herder and other German Romanticists such as Cornelius Jagdmann, but is best known in relation to Hegel's philosophy of history. In 1769 Herder wrote a critique of the work Genius seculi by the philologist Christian Adolph Klotz and introduced the word Zeitgeist into German as a translation of genius seculi (Latin: genius - "guardian spirit" and saeculi - "of the century").
The German Romanticists habitually attempted to reduce the past to essences and treated the Zeitgeist as a historical character in its own right, rather than a generalized description for an era.
