formed part of Jund Dimashq, which during the 9th century was attached to the administrative unit of Jund Filastin. The boundaries of the area and the ethnic nature of the people referred to by Herodotus in the 5th century BCE as Palaestina vary according to context. Sometimes, he uses it to refer to the coast north of Mount Carmel. Elsewhere, distinguishing the Syrians in Palestine from the Phoenicians, he refers to their land as extending down all the coast from Phoenicia to Egypt. Pliny, writing in Latin in the 1st century CE, describes a region of Syria that was "formerly called Palaestina" among the areas of the Eastern Mediterranean. Since the Byzantine Period, the Byzantine borders of Palaestina (I and II, also known as Palaestina Prima, "First Palestine", and Palaestina Secunda, "Second Palestine"), have served as a name for the geographic area between the Jordan River and the Mediterranean Sea. Under Arab rule, Filastin (or Jund Filastin) was used administratively to refer to what was under the Byzantines Palaestina Secunda (comprising Judaea and Samaria), while Palaestina Prima (comprising the Galilee region) was renamed Urdunn ("Jordan" or Jund al-Urdunn). Modern period Nineteenth-century sources refer to Palestine as extending from the sea to the caravan route, presumably the Hejaz-Damascus route east of the Jordan River valley. Others refer to it as extending from the sea to the desert. Prior to the Allied Powers victory in World War I and the partitioning of the Ottoman Empire, which created the British mandate in the Levant, most of the northern area of what is today Jordan formed part of the Ottoman Vilayet of Damascus (Syria), while the southern part of Jordan was part of the Vilayet of Hejaz. What later became Mandatory Palestine was in late Ottoman times divided between the Vilayet of Beirut (Lebanon) and the Sanjak of Jerusalem. The Zionist Organization provided its definition of the boundaries of Palestine in a statement to the Paris Peace Conference in 1919. The British administered Mandatory Palestine after World War I, having promised to establish a homeland for the Jewish people. The modern definition of the region follows the boundaries of that entity, which were fixed in the North and East in 1920–23 by the British Mandate for Palestine (including the Transjordan memorandum) and the Paulet–Newcombe Agreement, and on the South by following the 1906 Turco-Egyptian boundary agreement.
