The Zionist Commission for Palestine was a group chaired by Chaim Weizmann, president of the British Zionist Federation following British promulgation of the pro-Zionist, Balfour Declaration of 1917. The Commission was formed in March 1918 and went to Palestine to study conditions and make their recommendations to the British authorities. It consisted of Weizmann with Israel Sieff as secretary, and Joseph Cowen, Dr. M. D. Eder, Leon Simon from Britain; Commandante Angelo Levi Bianchini from Italy; and Professor Sylvian Levy from France. There were no representatives from America or Russia.
The Commission reached Palestine on 14 April 1918; it ran into difficulties with the British military administration (OETA), which was far from sympathetic to Zionist aspirations. The Commission had gone to Palestine with the consent of the British Government and stayed there for some years.
The Commission carried out initial surveys of Palestine and aided the repatriation of Jews sent into exile by the Ottoman Turks during World War I. It expanded the Palestine Office, previously founded by the ZO in 1908, into small departments for agriculture, settlement, education, land, finance, immigration, and statistics.
In June 1918, representing the Zionist Commission, Weizmann traveled to southern Transjordan to meet Emir Feisal, during the British advance from the south against the Ottoman Empire in World War I. The intended purpose was to forge an agreement between Feisal and the Zionist movement to support an Arab Kingdom and Jewish settlement in Palestine, respectively. Neither side considered it necessary to consult the wishes of the Palestinian Arabs.
