Short Answer 
The Holocaust’s mass murder of Jewish people primarily occurred through Einsatzgruppen mobile killing squads and the Final Solution, a systematic extermination plan involving extermination camps. Einsatzgruppen executed mass shootings in occupied territories, while the Final Solution, implemented in the early 1940s, led to the deaths of over six million Jews in camps like Auschwitz and Treblinka.
Identify the Methods of Mass Murder
During the Holocaust, the mass murder of Jewish people was executed primarily through two methods: the Einsatzgruppen and the Final Solution. The Einsatzgruppen were mobile killing squads that followed the German army, performing mass executions. Additionally, the Final Solution referred to the systematic extermination plan that led to the establishment of extermination camps.
Understand the Role of Mobile Killing Squads
The Einsatzgruppen played a crucial role in the early phases of the Holocaust. They conducted mass shootings across occupied territories in Russia and targeted various groups, including men, women, and children. Their operations aimed to eliminate entire Jewish communities, often using brutal methods that left thousands dead in a short period.
Recognize the Final Solution’s Implementation
The Final Solution was a formal Nazi policy established in the early 1940s, which consolidated extermination efforts in camps like Auschwitz and Treblinka. These camps became sites of systematic killings, leading to the tragic loss of over six million Jewish lives. While Kristallnacht represented an early wave of violent anti-Semitism, it did not involve mass murder but laid groundwork for future atrocities.
