April 20, 1889  
Adolf Hitler (1889–1945) is born in the Upper Austrian border town of Braunau am Inn, the son of tax collector Alois Hitler. Contrary to popular belief, he had no Jewish ancestors.

Hitler moves to Vienna. His impoverishment and residence in homeless shelters began the following year after he had squandered a generous inheritance. Hitler lives in Vienna until May 1913.

Hitler moves to Munich, Germany, in May, and in the following year he enlists in the German army to fight in World War I.

Adolf Hitler was a frontline soldier during World War I

Hitler is partially blinded in a mustard gas attack near Ypres in Belgium. News of the November 11, 1918, armistice reaches him as he is convalescing in a military hospital. World War I has a profound impact on Hitler and many other Germans. The impact of the conflict and its divisive peace has repercussions for decades to come, giving rise to a second world war and genocide committed under its cover.

September 12, 1919  
Hitler attends an early meeting of the German Workers' Party (Deutsche Arbeiterpartei-DAP), which will later become the Nazi Party under his leadership.

November 8–9, 1923 
Adolf Hitler and the Nazi Party lead a coalition group in an attempt to overthrow the government of Bavaria and initiate a “national revolution.” This so-called Beer Hall Putsch fails. Hitler and others are arrested for treason.

Hitler is convicted of high treason and sentenced to five years imprisonment, although he serves only one year. While in prison, he writes Mein Kampf (My Struggle). This infamous memoir proves significant in promoting key components of Nazism and its racial ideology. Published in two volumes in 1925 and 1926, it would sell one million copies in 1933, Hitler's first year in office.

Hitler establishes the SS (Schutzstaffel; Protection Squadrons). During the Nazi regime, the SS will become responsible not only for the German police force and the concentration camp system, but also for security, identification of ethnicity, settlement and population policy, and intelligence.

June 30-July 2, 1934
On Hitler’s order, Nazi leaders eliminate the leadership of the SA and kill other political enemies.

Summer 1936
Hitler opens the Berlin Olympics. 1936 represents a rare instance in which one nation, Germany, hosted both the winter and summer Olympic Games. Nazi Germany uses the 1936 Olympics for propaganda purposes. The Nazis promote an image of a new, strong, and united Germany while masking the regime’s targeting of Jews and Roma (Gypsies) as well as Germany’s growing militarism.

Hitler meets with the leaders of Britain, France, and Italy at a conference in Munich, Germany, on September 29–30, 1938, in which they agree to the German annexation of the Sudetenland in exchange for a pledge of peace from Germany. Six months later, Hitler moves against the Czechoslovak state.

December 11, 1941
In the aftermath of the Japanese attack on Pearl Harbor, Nazi Germany and its ally Italy declare war on the United States, despite the fact that the US had declared war only against the Empire of Japan.  In less than a year, American ground troops will fight German forces in North Africa.

April 30, 1945
Hitler commits suicide in an underground bunker in Berlin rather than face capture by advancing Soviet forces.

The International Military Tribunal (IMT) at Nuremberg decides not to try Adolf Hitler, Heinrich Himmler, and Joseph Goebbels in absentia. All three had committed suicide before the end of the war. In doing so, the IMT wished to avoid creating the impression that they might still be alive.
