At the end of the 19th century, with the suppression of the revolutions of 1848, many Europeans still desired reform. In this desire the yearning for unification began to make its way. As the likelihood of unification in places like Germany and Italy began to intensify, Europeans with liberal views quickly began to harbor a nationalistic way of thinking. Many leaders of this school of thought were supporters of the British statesman Benjamin Disraeli. Disraeli gave a famous speech at the Crystal Palace in London, in 1872. In his speech he challenged Europeans to choose their own path. The two paths were to either promote global imperial expansion or embrace insignificance in world affairs (Perry 151). This aroused the spirit of loyalty in many European citizens and inspired many loyalty speeches and publications. These loyalists included Hermann Ahlwardt and Karl Pearson in “The Semitic Race Against the Teutonic Race” and “National Life from the Standpoint of Science,” respectively. The beginnings of nationalist extremism threatened to destroy the peaceful ideals that emerged with the Enlightenment. European nationalists combined the ideas of Social Darwinism with extreme nationalism and soon became intolerant and irrational. By the end of the 19th century, Jews enjoyed legal equality in most places; however, having already endured anti-Semitism for hundreds of years, Jews began to see increased persecution against their people. Jews had suffered pogroms, unjust impositions, and had been denied just offices throughout Europe. Racists said that Jews were different, and therefore inferior, physically, intellectually, and spiritually (Perry 146). Hermann Ahlwardt, member of the Reichstag, had strong ideas against the Jews and... halfway through the paper... and will no longer progress; there will be nothing that can restrain the fertility of the inferior strains; the implacable law of heredity will not be controlled and guided by natural selection. Man will stagnate…” In this quote, Pearson makes it clear that any mixing of races would be socially and scientifically detrimental to man. extremists began to tear down those ideals including promoting hatred against certain groups for their physical differences. The abuses lead to growing unrest among different peoples who once lived together, albeit shakily. This harmful approach to nationalism stunted the growth and morality of Europeans and culminated in even greater turmoil as racist arrogances began to bleed across Europe..
