Anti-Semitism

When anti-Semitism is associated with Germany, many think first of the Nazi period. However, anti-Semitism existed politically in the Imperial period and still exists in the Federal Republic of Germany. 

Nevertheless, Nazism changed the perception of anti-Semitism socially and politically. That's not to say some form of anti-Semitism was benign during the Imperial period, rather that a notorious ideology can become even more deadly when socio-economic situations are influx and a large number of "haves" become "have nots".
