Who was elected elected President of Germany in 1925 and whose death led to the referendum on merging the posts of Chancellor and President?
German referendum, 1934 A referendum on merging the posts of Chancellor and President was held in Germany on 19 August 1934, after the death of President Paul von Hindenburg 17 days earlier. The German leadership sought to gain approval for Adolf Hitler's assumption of supreme power. The referendum was associated with widespread intimidation of voters, and Hitler used the resultant large "yes" vote to claim public support for his activities as the "de facto" head of state of Germany. In fact, he had assumed these offices and powers immediately upon von Hindenburg's death and used the referendum to legitimize this move, taking the title "Führer und Reichskanzler" (Führer and Chancellor).
Otto of Bavaria Otto (German: "Otto Wilhelm Luitpold Adalbert Waldemar" ; 27 April 1848 – 11 October 1916), was King of Bavaria from 1886 to 1913. However, he never actively reigned due to severe mental illness; his uncle, Luitpold, and cousin, Ludwig, served as regents. Ludwig deposed him in 1913 a day after the legislature passed a law allowing him to do so, becoming king in his own right.
