During World War I, it was captured by the United Kingdom as part of the Sinai and Palestine campaign. Between 1919 and 1922, the League of Nations created the Mandate for Palestine, which directed the region to be under British administration as Mandatory Palestine. Tensions between Jews and Arabs escalated into the 1947–1949 Palestine war, which ended with the territory of the former British Mandate divided between Israel vis-à-vis Jordan (in the West Bank) and Egypt (in the Gaza Strip); later developments in the Arab–Israeli conflict culminated in Israel's seizure of both territories, which has been among the core issues of the ongoing Israeli–Palestinian conflict. History of the name Modern archaeology has identified 12 ancient inscriptions from Egyptian and Assyrian records recording likely cognates of Hebrew Pelesheth. The term "Peleset" (transliterated from hieroglyphs as P-r-s-t) is found in five inscriptions referring to a neighboring people or land starting from c. 1150 BCE during the Twentieth dynasty of Egypt. The first known mention is at the temple at Medinet Habu which refers to the Peleset among those who fought with Egypt in Ramesses III's reign, and the last known is 300 years later on Padiiset's Statue. Seven known Assyrian inscriptions refer to the region of "Palashtu" or "Pilistu", beginning with Adad-nirari III in the Nimrud Slab in c. 800 BCE through to a treaty made by Esarhaddon more than a century later. Neither the Egyptian nor the Assyrian sources provided clear regional boundaries for the term. The first clear use of the term Palestine to refer to the entire area between Phoenicia and Egypt was in 5th century BCE Ancient Greece, when Herodotus wrote of a "district of Syria, called Palaistinê" () in The Histories, which included the Judean mountains and the Jordan Rift Valley. Approximately a century later, Aristotle used a similar definition for the region in Meteorology, in which he included the Dead Sea. Later Greek writers such as Polemon and Pausanias also used the term to refer to the same region, which was followed by Roman writers such as Ovid, Tibullus, Pomponius Mela, Pliny the Elder, Dio Chrysostom, Statius, Plutarch as well as Romano-Jewish writers Philo of Alexandria and Josephus. The term was first used to denote an official province in c. 135 CE, when the Roman authorities, following the suppression of the Bar Kokhba Revolt, combined Iudaea Province with Galilee and the Paralia to form "Syria Palaestina".
