Making extensive use of archives, Aly provides a detailed reconstruction of the Final Solution. He illustrated the lunacy of Nazi race policy and the variety of agencies that went into the gradual shaping of a policy of all-out genocide.

Tracing the rise of racist and eugenic ideologies, Henry Friedlander explores in chilling detail how the Nazi program of secretly exterminating the handicapped and disabled evolved into the systematic destruction of Jews and Gypsies. He describes how the so-called euthanasia of the handicapped provided a practical model for the later mass murder, thereby initiating the Holocaust. The Nazi regime pursued the extermination of Jews, Gypsies, and the handicapped based on a belief in the biological, and thus absolute, inferiority of those groups. To document the connection between the assault on the handicapped and the Final Solution, Friedlander shows how the legal restrictions and exclusionary policies of the 1930s, including mass sterilization, led to mass murder during the war. He also makes clear that the killing centers where the handicapped were gassed and cremated served as the models for the extermination camps. Based on extensive archival research, the book also analyzes the involvement of the German bureaucracy and judiciary, the participation of physicians and scientists, and the nature of popular opposition.

This groundbreaking work is the most detailed, carefully researched, and comprehensive analysis of the evolution of Nazi policy from the persecution and "ethnic cleansing" of Jews in 1939 to the Final Solution of the Holocaust in 1942.

Counterfactual history of the Jewish past inviting readers to explore how the course of Jewish history might have been different.

The first ever study to combine a detailed re-appraisal of the development of the genocide of Europe's Jews with full consideration of Nazi policies against other population groups and a comparative analysis of other genocides from the twentieth century.

This volume presents a comprehensive, multifaceted picture both of the destructive dynamic of the Nazi leadership and of the attitudes and behavior of ordinary Germans as the persecution of the Jews spiraled into total genocide.

Ultimately this would lead to the sinister 'adjusting' of the ratio between what were perceived as 'productive' and 'unproductive' population groups.".
