On Heinrich von Sybel's death, Treitschke succeeded him as editor of the "Historische Zeitschrift". He had outgrown his early Liberalism and become the chief panegyrist of the House of Hohenzollern. He made violent and influential attacks on all opinions and all parties which seemed in any way to be injurious to the increasing power of Germany. He endorsed Chancellor Otto von Bismarck and his program to subdue the Socialists, Poles and Catholics ("Kulturkampf"), but the attempts were unsuccessful because the victims organized themselves and used universal male suffrage to their advantage in the Reichstag until Bismarck finally relented.
