The Nazi party began systematically discriminating against Jews in Germany starting in 1933. Over time, their policies became increasingly harsh, restricting where Jews could live and work and what rights they had. The Nazis used propaganda, scientific racism, and new laws to dehumanize Jews and justify treating them as inferior. Jews were segregated into ghettos and later deported to concentration and death camps, where most were murdered in gas chambers or died of starvation, disease, and abuse. By the end of World War 2, the Nazis had killed approximately 6 million European Jews as part of the systematic genocide known as the Holocaust or the Final Solution.
