BackgroundUnited Nations Special Committee on PalestineAd Hoc CommitteeThe VoteReactionsSubsequent EventsResolution 181 as A Legal Basis For Palestinian StatehoodRetrospectSee AlsoBibliographyThe British administration was formalized by the League of Nations under the Palestine Mandate in 1923, as part of the Partitioning of the Ottoman Empire following World War I. The Mandate reaffirmed the 1917 British commitment to the Balfour Declaration, for the establishment in Palestine of a "National Home" for the Jewish people, with the prerogative to carry it out.A British census of 1918 estimated 700,000 Arabs and 56,000 Jews. In 1937, following a six-month-long Arab General Strike and armed insurrection which aimed to pursue national independence and secure the country from foreign control, the British established the Peel Commission. The Commission concluded that the Mandate had become unworkable, and recommended Partition into an Arab state linked to Transjordan; a small Jewish state; and a mandatory zone. To address problems arising from the presence of national minorities in each area, it suggested a land and population transfer involving the transfer of some 225,000 Ara...Get price
