A referendum supported the recent merging of the posts of chancellor and president of Germany, consolidating Adolf Hitler's assumption of supreme power.

A referendum on merging the posts of Chancellor and President was held in Nazi Germany on 19 August 1934, seventeen days after the death of President Paul von Hindenburg. 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 significant electoral fraud.

The chancellor of Germany, officially the federal chancellor of the Federal Republic of Germany, is the head of the federal government of Germany. The chancellor is the chief executive of the Federal Cabinet and heads the executive branch. The chancellor is elected by the Bundestag on the proposal of the federal president and without debate. During a state of defence declared by the Bundestag the chancellor also assumes the position of commander-in-chief of the Bundeswehr.

The president of Germany was the head of state under the Weimar Constitution, which was officially in force from 1919 to 1945, encompassing the periods of the Weimar Republic and Nazi Germany.

Adolf Hitler was an Austrian-born German politician who was the dictator of Germany during the Nazi period from 1933 until his suicide in 1945. He rose to power as the leader of the Nazi Party, becoming the chancellor in 1933 and then taking the title of Führer und Reichskanzler in 1934. His invasion of Poland on 1 September 1939 marked the start of the Second World War. He was closely involved in military operations throughout the war and was central to the perpetration of the Holocaust: the genocide of about six million Jews and millions of other victims.
