The newly Nazi ghettos were constructed in Germany. Starting with the invasion of Poland during World War II, the rule of Nazi Germany established a ghetto for occupation in Europe to secede and seize Jews, and sometimes led the Romans to further their exploitation in cities and small parts of cities. There were different types of Ghettos;
1. Open ghettos
2. Closed or sealed ghettos
3. The abolished or extermination ghettos
