After the Nazis conquered territory in Europe, they forced Jewish people to live in ghettos.
Step-by-step explanation:
After the Nazis had conquered a lot of territory in Europe, they forced many Jewish people to live in ghettos in order to segregate them.
Nazis believed Jewish people were bad people and that Nazis were the superior race. This hate did not just stop at Jewish people, but also disabled people, mentally ill people, Jehovah's Witnesses, and other groups. The Nazis wanted to first segregate these people but later would come the Final Solution, which was putting Jewish people in concentration camps to kill them.
By forcing Jewish people to live in ghettos, the Nazis believed they were preventing the spread of diseases that they believed Jewish people may have had. They also wanted to have full control over Jewish people by forcing them to live in one spot, along with segregating them from people they deemed as the "superior race."
