Volume XIV of the letters of Chaim Weizmann, written in the period between the Sixteenth Zionist Congress and the British Government's Statement of Policy of 21 October 1930, gives a central place to the establishment of an enlarged Jewish Agency by the inclusion of non-Zionists, and to the political struggle which followed the 1929 disturbances in Palestine. The achievement of the Jewish Agency would undoubtedly have marked a high point in Weizmann's Zionist leadership were it not diminished by the world-wide economic slump and a crisis in relations with the British Government.
