The letter

The declaration took the form of a short letter, dated 2 November 1917, from Lord Arthur James Balfour, the British Foreign Secretary, to Lord Lionel Walter de Rothschild, approved by the British cabinet. It stated that His Majesty’s Government viewed with favour the establishment in Palestine of a national home for the Jewish people and would use their best endeavours to facilitate it, it being clearly understood that nothing would be done to prejudice the civil and religious rights of the existing non-Jewish communities in Palestine. Incorporated into Britain’s Mandate by the League of Nations, it was the guiding principle of British rule for thirty years.

A wartime promise

The declaration was drafted during the First World War. The encyclopedia reads the British aims as winning Jewish support in the United States, Germany and Russia for the war effort, and securing British claims to Palestine after the war to shore up control over Egypt and the Suez Canal. It directly contradicted an earlier secret promise by Sir Henry McMahon, Britain’s High Commissioner in Egypt, to Sharif Hussein of Mecca that Britain would support Arab independence after the war. British troops took Jerusalem in December 1917, and the occupation of the whole country was complete by October 1918.

Opposition

Palestine’s Arab population opposed the Balfour policy from the start: in demonstrations and clashes in April 1920 and May 1921, at the Palestine Arab Congresses, and in delegations to London. From 1918 to 1936 Palestinians marked 2 November, Balfour Day, as a day of mourning, with demonstrations and one-day general strikes.
