Teribus, the refugee camps are the 'home' of Palestinians who fled what is now Israel proper, and ended up in the West Bank.

"Why did the Jordanians invade and occupy land that belonged to Palestine, occupy it from 1948 to 1967 and force the Arab Palestinians into refugee camps?"

As I said before (several times already, Teribus), Jordan had worked out a deal with members of the Jewish leadership (most notably, Golda Meir) in which Jordan agreed to not attack any of the areas allotted to Jews in the partition plan (and with the exception of some parts of the Jerusalem's Jewish quarter, they honored this agreement fully), and in return, Jordan would take the West Bank. I do not approve of this deal, and I think the Palestinians have a valid complaint against Jordan for having done this. However, I am confident that had Jordan not struck such a deal, the West Bank would have been taken by Israel in the 1948/1949 war. The Arabs did not attack any areas that had been allotted to Jews in the partition plan. They only fought in areas where Jews were trying to take land that had been allotted to the Palestinians in the partition plan.

The Palestinians ended up in the refugee camps because there is only just so much room and there are just so many resources in the West Bank, and Jordan had every reason to expect that the refugees would be allowed to return to where they came from originally, since Israel was in violation of international law, the Geneva Conventions, and UN Resolutions in preventing them from doing so.

This is something that I have even posted previously right here in this thread. This is why I have no time for your snaky bullshit, Teribus. You just keep asking the same dishonest questions over and over and over as if you have never received a response to them the previous times you posted them. When you're not actively lying, you're trying to obfuscate because your racist hatemongering is a bankrupt ideology, and has no legitimate arguments to support it. Fortunately for the world, this ideology is dying out (slowly and agonizingly, unfortunately, but dying out nevertheless) as well it should.
