Why did Adolf Hitler do what he did?

He felt victimized by the Jews. he blamed a Jewish doctor for his mother's death, he blamed a Jewish professor for rejecting his artwork when he applied to the Academy of Fine Arts in Vienna, and he blamed them for the German loss of World War 1.

Hitler blaimed the Jews for Germany's economic problems. Many German Jews were prosperous. He was hungry for power and seized the opportunity when Germany had so many troubles. Hitler was interested in art. He had a Jewish art teacher who trashed his work and added to his hatred.

because he had fought in world war 1 and when the Germans had lost he decided to become ruler of Germany and he sent out troops to bomb England basicly to get revenge...

then he caused world war 2 by doing that crazy stuff.

Improvements(by Jacob :P):

Some think that Hitler started the Holocaust because the doctor that was in charge of his mother's health messed up, killing his mother who he was close to. This is completely incorrect. Hitler was actually very appreciative of Dr. Eduard Bloch (the Jewish doctor who treated Klara Hitler at the end of her life), and after Hitler took control of Germany and Austria, he gave Dr. Bloch a special honor, allowing him to emigrate to the United States unharmed in 1940. Dr. Bloch lived in New York City until his death just after Germany surrendered in 1945.

The bombing of England was called the Blitz of London.

An interesting side note. Because Hitler has served in World War 1 and saw the bravery of the Canadians(Oh ya, We just don't have good beer) he told the German bomber and fighter planes not to hit the Vimy Ridge Memorial. Because the memorial was white and could be seen easily at night the Allies used the memorial as a point of reference to know how close they were to were the Germans were hiding out. I just thought this was relevant because of the reference to Hitler serving in World War 1.

The hatred of the Jewswere not just thought of by Hitler but by many! the whole reason of how and why he got into power is very complicated and lasted a period from 1923-1933 then 1933-1939 in simple terms, after the war he was sent by the intelligence corps to mointor a right wing group D.A.P the German workers party.( which later became NSDAP nationlsozialistische deutsche arbeitet partei or more commonly NAZI party. He made a few speeches and ended up getting selected as leader, he led "prutsch's" attacks on Parliament. He was imprisoned in the early 20's where he wrote his first volumes of mein kampf. The party grew stronger and stronger until Jan 30th 1933 where he was elected (all by the book) to be chancellor. He started building the German forces, and implementing his ideas, boycotting Jewish shops business' etc until 1939 when he invaded Poland.

Obviously this is a very very brief list of events and indeed, is very complicated.

Hitler grew up in Austria, and worked with a bunch of Jews, this led him to believe that they were inferior. He might have thought that he was helping people. Maybe he just wanted power. +++++

TO answer a couple of points by Prioktan: 4) Hitler's bizarre racial attitudes were by no means unusual then. The pseudo-science to which Prioktan refers, was "Eugenics", a theory that it would be possible to breed humans selectively to produce people of "ideal" characteristics. Another contributor to 'Answers' has said that the alleged reliance by the Nazis on physical appearance was not really so - Hitler was not very worried by looks but saw the Jews as a separate race, and an inferior one at that, the 'untermenschen' along with Romanies, coloureds and those considered "defectives": homosexuals and the mentally ill. The war against Hitler, and what it uncovered about the Nazi regime, thankfully exposed and destroyed eugenics as the revolting nonsense it was. Yet it had been an attractive concept for many who would not have dreamt of killing those coming up to standard, and may explain the Swiss anti-gypsy campaign in the 1940s-50s. The Swiss did not kill anyone, but kidnapped Romany children and farmed them out under new, non-gypsy identities to State-approved couples, leaving their elders simply to die out naturally. Same idea - just less cruel in carrying out. 5) Actually, although some anti-Semitism was common throughout many Western nations in the mid-20C, the USA and UK took in very many Jews and others fleeing from the Nazis, before the outbreak of war and even, when possible, during the War. Britain already had a good many Jews and by and large, regarded them amicably.

It's chilling but worth comparing the Nazi and its contemporary USSR regimes, and later tyrannies. I would put ISIS alongside the Nazis and possibly Stalin's rule; groups like Bokul Harun with the Khmer Rouge, for example. Whatever their pronounced theory, self-justification and abilities or not as national administrators, they all share the same trait: a leader or cabal having nothing but amorality, selfishness, cruelty and lust for power.
