Adolf Hitler was born on April 20th, 1889 in Austria. After schooling, Hitler moved to Munich. Screened for Austrian military service in February 1914, though he was stamped unfit for the service it was when the World War I broke out. He petitioned Bavarian King Louis III to be allowed to serve, and one day after submitting that request, he was notified that he would be permitted to join the 16th Bavarian Reserve Infantry Regiment. After some eight weeks of training, Hitler was deployed in October 1914 to Belgium, where he participated in the First Battle of Ypres.
He greeted the war with enthusiasm, as a great relief from the frustration and aimlessness of civilian life. He found discipline and comradeship satisfying and was confirmed in his belief in the heroic virtues of war. In 1923, he attempted to seize power in a failed coup in Munich and was imprisoned. In jail, he dictated the first volume of his autobiography and political manifesto Mein Kampf. After his release in 1924, Hitler gained popular support by attacking the Treaty of Versailles and promoting Pan-Germanism, antisemitism, and anti-communism with charismatic oratory and Nazi propaganda. He frequently denounced international capitalism and communism as part of a Jewish conspiracy.
Nazi Party became the largest elected party by July 1932. His aggressive foreign policy is considered the primary cause for World War II. In June 1941, Hitler ordered an invasion of the Soviet Union. By the end of 1941, German forces and the European Axis powers occupied most of Europe and North Africa. In December 1941, shortly after Japan attacked Pearl Harbour, Hitler declared war on the United States, bringing it directly into the conflict.
The failure to defeat the Soviet Union and the US entry into the war scene forced Germany to be defensive and they faced a series of defeats. In the final days of the war, during the Battle of Berlin in 1945, he married his longtime lover Eva Braun. Less than two days later, on 30 April 1945, the two committed suicide to avoid capture by the Soviet Red Army; their corpses were burned.
