It's not that easy to answer.
Hitler believed there was giant Jewish conspiracy behind any major world powers, secondly he believed that the jews are the lowest human race that just feed off superior races like parasites.
Hitler gave them a scapegoat to blame for the economical crisis in germany with some easy explanations that anyone could understand.
Hitler promised them work, property and anything else than the common german worker did not had during this time.
Secondly, Hitler was against democracy, at this point in history the democracy was hated in germany because many people believed that democrats "backstabbed" german forces in the 1st WW.
http://en.wikipedia.org/wiki/Dolchsto%C3%9Flegende as you can see in those pictures, some blamed the jews there as well.
Germany was from a political standpoint not even close to stable, every 3-6 months new elections and such.
Many military officers supported hitler as well because he promised to break the treaty of versaille. (No Air Force, army is only followed to have 100.000 Soldiers, No Tanks and so forth)
I could go on with this list but if you want to simplify such a delicate topic by saying "Hitler used the German's Pride" i say you are wrong, he used their misery.
During this timeframe he mostly established the Nazi State, arming the Wehrmacht (German Army during 1933-1945) and putting Jews, other "lesser" races and political opposition into camps.
His Pride, or rather Insanity catched up with him when the war started, overconfident with german success in Poland and French he started the russian invasion (We'll be back at Christmas, they said) and then his Insanity started kicking in when he refused to listen to the most basic advices of his generals.
Even though i totally jumped here on Godwin's law, i'd rather refrain from simplyfing such historical matters for the discussion of an Online Game, mostly because in real history there are much more factors that come into play.
