From Wikipedia: http://en.wikipedia.org/wiki/Palestine
Palestine (from Latin: Palaestina; Hebrew: ארץ־ישראל Eretz-Yisra’el, formerly also פלשתינה Palestina; Arabic: فلسطين Filasṭīn, Falasṭīn, Filisṭīn) is one of several names for the geographic region between the Mediterranean Sea and the Jordan River and various adjoining lands.
Different geographic definitions of Palestine have been used over the millennia, and these definitions themselves are politically contentious. In recent times, the broadest definition of Palestine has been that adopted by the British Mandate, and the narrowest is that used in contemporary politics today, called the Palestinian territories, which are the West Bank and Gaza Strip. Other English names for this region include: Canaan, Land of Israel, and Holy Land.
