Palestinians refer to their 1948 expulsion as the Nakba, Arabic for catastrophe. Some 700,000 Palestinians — a majority of the prewar population — fled or were driven from their homes before and during the 1948 Arab-Israeli war that followed Israel’s establishment.

The Oslo negotiations of the 1990s rejected the notion of removing Palestinians from Gaza. In fact, keeping the refugees in Gaza was central to the premise of a two-state solution. At the same time, questions over the right of refugees to return to their original homelands in what is now Israel were shelved.
