How are the Holocaust and WWII different?

While the Holocaust was Germany’s active destruction of European Jewry and other minority groups, WWII was an international war of conquest where Germany invaded and occupied neighboring countries and other countries of the world fought back. The Holocaust started in 1933 with restrictions against the Jews. WWII started in 1939 when Nazi Germany invaded Poland. Hitler was the malefactor behind both the Holocaust and WWII. As Germany continued to incorporate other European nations into the Nazi empire, the Jews of those nations became victims of the Holocaust.
