Hebrew-language names were coined for the place-names of Palestine throughout different periods under the British Mandate; after the establishment of Israel following the 1948 Palestinian expulsion and flight and 1948 Arab–Israeli War; and subsequently in the Palestinian territories occupied by Israel in 1967. A 1992 study counted c. 2,780 historical locations whose names were Hebraized, including 340 villages and towns, 1,000 Khirbat (ruins), 560 wadis and rivers, 380 springs, 198 mountains and hills, 50 caves, 28 castles and palaces, and 14 pools and lakes. Palestinians consider the Hebraization of place-names in Palestine part of the Palestinian Nakba.
