dolf Hitler (German: [ˈadɔlf ˈhɪtlɐ] (About this sound listen); 20 April 1889 – 30 April 1945) was a German politician who was the leader of the Nazi Party (Nationalsozialistische Deutsche Arbeiterpartei; NSDAP), Chancellor of Germany from 1933 to 1945 and Führer ("Leader") of Nazi Germany from 1934 to 1945.[a] As dictator, Hitler initiated World War II in Europe with the invasion of Poland in September 1939, and was central to the Holocaust.

Hitler was born in Austria—then part of Austria-Hungary—and was raised near Linz. He moved to Germany in 1913 and was decorated during his service in the German Army in World War I. In 1919, he joined the German Workers' Party (DAP), the precursor of the NSDAP, and was appointed leader of the NSDAP in 1921. In 1923, he attempted to seize power in a failed coup in Munich and was imprisoned. While in jail he dictated the first volume of his autobiography and political manifesto Mein Kampf ("My Struggle"). After his release from prison in 1924, Hitler gained popular support by attacking the Treaty of Versailles and promoting Pan-Germanism, anti-semitism and anti-communism with charismatic oratory and Nazi propaganda. He frequently denounced international capitalism and communism as being part of a Jewish conspiracy.

By 1933, the Nazi Party was the largest elected party in the German Reichstag, but did not have a majority, and no party was able to form a majority parliamentary coalition in support of a candidate for chancellor. This led to former chancellor Franz von Papen and other conservative leaders persuading President Paul von Hindenburg to appoint Hitler as Chancellor on 30 January 1933. Shortly after, the Reichstag passed the Enabling Act of 1933, which began the process of transforming the Weimar Republic into Nazi Germany, a one-party dictatorship based on the totalitarian and autocratic ideology of National Socialism. Hitler aimed to eliminate Jews from Germany and establish a New Order to counter what he saw as the injustice of the post-World War I international order dominated by Britain and France. His first six years in power resulted in rapid economic recovery from the Great Depression, the abrogation of restrictions imposed on Germany after World War I and the annexation of territories that were home to millions of ethnic Germans which gave him significant popular support.
