A report presented to the British Parliament in October 1921 by a Commission of Inquiry, chaired by Chief Justice of Palestine Thomas Haycraft, set up in order to investigate the 1921 riots in and around Jaffa. The commission found that the primary cause for the "disturbances" was Arab discontent over the political and economic consequences of continued Jewish immigration, as well as perceived pro-Jewish bias by Mandatory authorities. The report was followed by the 1922 Palestine White Paper, a policy document aimed to conform with its findings.
