During the Byzantine period c. 390, the imperial province of Syria Palaestina was reorganized into: Palaestina Prima, Palaestina Secunda,[20] and Palaestina Salutaris.[20] Following the Muslim conquest, place names that were in use by the Byzantine administration generally continued to be used in Arabic.[4][21] The use of the name "Palestine" became common in Early Modern English,[22] was used in English and Arabic during the Mutasarrifate of Jerusalem. In the 20th century the name was used by the British to refer to "Mandatory Palestine", a mandate from the former Ottoman Empire which had been divided in the Sykes–Picot Agreement.[23] The term was later used in the eponymous "State of Palestine".[24] Both incorporated geographic regions from the land commonly known as Palestine, into a new state whose territory was named Palestine.
