Hitler was a charismatic speaker who was able to reach out to people in all classes of society.
He had blue eyes, short clipped hair and a funny squared moustache.
He was obsessed with the occult and borrowed the swastika symbol from the Hindus. He was also vegetarian and not very interested in sex.
He married two times but never had children of his own, though he loved children a lot.
He hated his father but worshipped his mother, but she died when he was barely a teen. Hitler wasn't a successful student, he was dismissed from the art school/college he went to in Vienna. He tried selling his art in Vienna without much success. He saw how prosperous the Jews were while he had no job and was prowling the streets. Later on, when he came to power, he made anti-semitism (hatred of the Jews) part of the Nazi policies.
He was overjoyed when the First World War came. He fought with such bravery and that won him an Iron Cross. He was very bitter about the Treaty of Versailles and accused the Weimar politicians for having backstabbed the army!
Later, he joined the Nazi party and was hungry for power. IN 1923, he unsuccessfully tried to take over Munich. His trial got media attention and his impressive speaking skills made him serve only 9 months in prison although high treason deserved a life sentence. During the 9 months, he wrote his famous book Mein Kampf (My struggles)
He then sought to gain power by legal means.
