DP, Displaced Persons, Camps were built after liberation of the Jews because they had their houses taken by the Nazis before being taken to the camps, after liberation, they had nowhere to go, when they went home they found someone else living in their homes.
After liberation, the Jews should have been excited, right? Well they were not, not only because they had no home, but also because the Nazis had already planted anti-semitism into everyones heads.

So the Jews really had nowhere to go, and nothing to do; they were allowed, but not welcome.
