Arthur Moeller van den Bruck (23 April 1876 – 30 May 1925) was a German cultural historian and writer, best known for his controversial 1923 book Das Dritte Reich (The Third Reich), which promoted German nationalism and was a strong influence on the Conservative Revolutionary movement and later the Nazi Party.
He did not support the party, however.
From 1906 to 1922, he also published Elisabeth Kaerrick's first full German translation of Dostoyevsky's works.
