Did the concept of antisemitism begin with the Holocaust?
The holocaust was like a kick-starter for antisemitism, It didn't invent antisemitism.
The main reasons are: * Jew-baiting, a desire to mock the victims, the survivors and their descendants (antisemitism). * A desire to rehabilitate the Nazis. * Some believe that Israel has exploited the Holocaust and think the easiest solution is to deny the Holocaust. No serious historian has any time for Holocaust denial.
antisemitism is the longest hatred cause in history that still survives today. Among the most common manifestations of antisemitism throughout history were pogroms. The first such incident to be labeled a pogrom is believed to be anti-Jewish rioting in Odessa in 1821. That was in Russia. But this has been practice during millennial.
He wasn't involved. The Holocaust didn't really start until well after he had died. He was indirectly involved in that he had played a role in Hitler's takeover of Germany in 1933. The Nazi Party's strong antisemitism was well known, but he couldn't have known that it would lead to the horrors of the Holocaust.
The Holocaust has nothing to do with natural selection, or vice versa. The Holocaust was the result of atrocious crimes committed under the leadership of a few madmen, inspired by a long tradition of antisemitism. Natural selection is a model that describes differential reproductive success in natural populations, under natural circumstances.
The usual disintinction is between (traditional) religious antisemitism and racial antisemitism. The latter arose after religious toleration was accepted in most European countries and religious antisemitism lost much of its force. Racial antisemitism arose from about 1870 onwards and operates with conspiracy theories.
