The Palestinian right of return is the political position or principle that Palestinian refugees, both first-generation refugees (c. 30,000 to 50,000 people still alive ) and their descendants (c. 5 million people ), have a right to return, and a right to the property they themselves or their forebears left behind or were forced to leave in what is now Israel and the Palestinian territories (both formerly part of the British Mandate of Palestine), as part of the 1948 Palestinian exodus, a result of the 1948 Palestine war, and due to the 1967 Six-Day War.
Formulated for the first time on 27 June 1948 by United Nations mediator Folke Bernadotte, proponents of the right of return hold that it is a sacred right, as well as a human right, whose applicability both generally and specifically to the Palestinians is protected under international law. This view holds that those who opt not to return or for whom return is not feasible, should receive compensation in lieu. Proponents argue that Israel's opposition stands in contrast with its Law of Return that grants all Jews the right to settle permanently, while withholding any comparable right from Palestinians.
Opponents of the right of return hold that there is no basis for it in international law, and that it is an unrealistic demand. The government of Israel does not view the admission of Palestinian refugees to their former homes in Israel as a right, but rather as a political issue to be resolved as part of a final peace settlement.
The number of Palestinian refugees of the 1948 war is estimated at between 700,000 and 800,000, and another 280,000 to 350,000 people were refugees of the 1967 war. Approximately 120,000–170,000 among the 1967 refugees are believed to have also been refugees from the 1948 war, fleeing a second time. Today, the estimated number of Palestinian refugees exceeds four million. The right of return has been of great importance to Palestinians since then.
