During the Holocaust over six million Jews were murdered. "Holocaust" is a word of Greek origin meaning "sacrifice by fire." The cause of the Holocaust was that the Germans believed they were "racially supierier", and Jews were a threat to German society.
Germans not only target Jews, they targeted other groups as well. Including the diabled, Slavs, gypsies, and many more. "Other groups were persecuted on political, ideological, and behavioral grounds, among them Communists, Socialists, Jehovah's Witnesses, and homosexuals."
By 1945 the Germans had killed about 2 out of every 3 Jews in Europe. The "Final Solution" was the Nazi policy to murder the Jews of Europe.
To monitor Jewish population and to prepare for deportation, Jews lived in ghettos. Jews were deported to concentration camps. Concentration camps were extermination camps, killing camps.
German arms surrendered on May 7, 1945. Many survivors found shelter in "displaced persons camp". Displaced persons camps were camps that the allied powers had created for survivors. Beginning in 1948 and last until 1951 almost 700,000 migrated to Israel. Jews also migrated to the U.S.
