Adolf Hitler (20 April 1889 – 30 April 1945) was a German politician and leader of the Nazi Party (Nationalsozialistische Deutsche Arbeiterpartei; NSDAP). He rose to power as Chancellor of Germany in 1933, and as Führer in 1934. During his dictatorship from 1933 to 1945, he initiated World War II in Europe by invading Poland on 1 September 1939. He was closely involved in military operations throughout the war and was central to the perpetration of the Holocaust.

Hitler's actions and ideology are almost universally regarded as evil. According to historian Ian Kershaw, "Never in history has such ruination—physical and moral—been associated with the name of one man."

Hitler created a public image as a celibate man without a domestic life, dedicated entirely to his political mission and the nation. He met his lover, Eva Braun, in 1929, and married her on 29 April 1945, one day before they both committed suicide.

In September 1931, his half-niece, Geli Raubal, took her own life with Hitler's gun in his Munich apartment. It was rumoured among contemporaries that Geli was in a romantic relationship with him, and her death was a source of deep, lasting pain. Paula Hitler, the younger sister of Hitler and the last living member of his immediate family, died in June 1960.
