He was Graf von Bismarck-Schönhausen (Count Bismarck-Schönhausen) in 1865, then since 1871 Fürst von Bismarck (Prince Bismarck) and since 1890 the Herzog von Lauenburg (Duke of Lauenburg). First he did not want the duke title, but accepted it later.
Bismarck was very conservative and he was strongly connected to the monarchy. He was not a big supporter of democracy. His most important goal was to make Prussia stronger and he achieved that through the unification of Germany. Bismarck tried to stop the socialist movement and to reduce the power of the Catholic Church. One way to stop socialism was to make the working class happy. He did that by introducing many social reforms like public health and accident insurance, as well as pensions for old people.
