What was the chief reason for Adolf Hitler's anti-Semitism?

pure pragmatism. Anti-semitism was quite common and spread in all the Europe already in the 19th century. There were numerous anti-semite organizations in many European countries. In Germany after WW I defeat German extreme right accused Jews from the defeat (Jews were usually made responsible for the "decadence" phenomenon) and considered Weimar Republic as Jewish. This was quite common and usual opinion between Germans at that time. Hitler was aware of that so to get votes and popularity Hitler started preaching not only nationalism and socialism but also antisemitism. Like that he was able to win legally elections for the position of Kanzler (he took this position in January 1933).

Explanation: Hitler initiated very brutal antisemitic politics so he became soon very popular. He explained his strategy a long time before 1933 in his book Mein Kampf (My Struggle).
