During the 1947–1949 Palestine war, or the Nakba, around 400 Palestinian Arab towns and villages were forcibly depopulated by Israeli forces, with a majority being destroyed and left uninhabitable. Today these locations are all in Israel; many of the locations were repopulated by Jewish immigrants, with their place names replaced with Hebrew place names.
Arabs remained in small numbers in some of the cities (Haifa, Jaffa and Acre); and Jerusalem was divided between Jordan and Israel. Around 30,000 Palestinians remained in Jerusalem in what became the Arab part of it (East Jerusalem). In addition, some 30,000 non-Jewish refugees relocated to East Jerusalem, while 5,000 Jewish refugees moved from the Old City to West Jerusalem on the Israeli side. An overwhelming number of the Arab residents who had lived in the cities that became a part of Israel and were renamed (Acre, Haifa, Safad, Tiberias, Ashkelon, Beersheba, Jaffa and Beisan) fled or were expelled. Most of the Palestinians who remain there are internally displaced people from the villages nearby.
