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 as of 2012[update]) and their descendants (c. 5 million people as of 2012[update]), 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) during the 1948 Palestinian expulsion and flight (a result of the 1948 Palestine war) and the 1967 Six-Day War.
The right of return was initially formulated on 27 June 1948 by United Nations mediator Folke Bernadotte. Proponents of the right of return hold that it is 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. 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. The government of Israel, and its supporters, state that Palestinian refugees don't have the right of return under international law.
There is also significant concern about the demographic impact of the return of 5 million Palestinians to Israel, whose population is nearly 10 million. Some Palestinians, including Yasser Arafat, have supported some limits on the right of return to accommodate Israel's demographic concerns.
