Seated center is Sir Walter Shaw, chairman of the commission. In its report the commission concluded that the fundamental cause of the 1929 outbreak was the Palestinians' feeling of "disappointment of their political and national aspirations and fear for their economic future ." It recommended that British policies on Zionist mass immigration to and land acquisition in Palestine should give due consideration to Palestinian interests and grievances.
