Palestine (Greek: Παλαιστίνη, Palaistinē; Latin: Palaestina; Hebrew: ארץ־ישראל Eretz-Yisra’el, formerly also פלשׂתינה, Palestina; Arabic: فلسطين Filasṭīn, Falasṭīn, Filisṭīn) was a conventional name, among others, used between 450 BC and 1948 AD to describe the geographic region between the Mediterranean Sea and the Jordan River, and various adjoining lands.
The boundaries of the region have changed throughout history, and were first defined in modern times by the Franco-British boundary agreement (1920) and the Transjordan memorandum during the British Mandate for Palestine. Today, the region comprises the country of Israel and the Palestinian territories.
Today, the term Palestine is also used to refer to either the Palestinian territories or the State of Palestine.
Other terms for the same area include Canaan, Zion, the Land of Israel, Syria Palaestina, Southern Syria, Jund Filastin, Outremer, the Holy Land and the Southern Levant.
