Answer:
Hitler blamed the Jews for WW1 and the situation for what happened in Germany.
The oldest book would probably have to be The Bible...
Hitler's final solution to the "Jewish problem" was extermination. Those who were stronger were sent to labor camps to work until they were deemed "unworthy". Those who were deemed "unworthy" in the beginning and later on, were sent to extermination camps, where they were gassed and then were sent to the crematorium, and then buried in mass graves.
