Night is one person's experience of the Holocaust—the Nazi's effort to exterminate the Jews of Europe, largely by sending the Jews to concentration camps where they were worked to death, or worked to near death and then killed. By the end of World War II, Adolf Hitler had systematically murdered six million Jews and millions of gypsies, Communists, homosexuals, and other people the Nazis considered undesirable. Jews in Hungary were not directly affected until 1944, by which point the concentration camps had been in operation for some time. Yet information was unreliable and difficult to come by. The Jews of Wiesel's town of Sighet either did not know or could not believe the extent of the Nazi's so-called "Final Solution." In the spring of 1944, the Nazis effectively took control of the Hungarian government, and Adolf Eichmann, Hitler's architect of the Holocaust, oversaw the deportation of Hungary's sizable Jewish population to concentration camps in Germany and Poland.
