Labor leader and head of the Political Department of the Jewish Agency Chaim Arlosoroff is murdered on a Tel Aviv beach. Controversy ensues amidst competition for leadership of the Jewish Agency between the right wing Revisionists and the left leaning laborites. The murder remains unsolved, but shows that Zionists could and would differ violently over direction, pace, and operation of their national movement. Shortly after the assassination, David Ben-Gurion becomes head of the political department of the Jewish Agency (essentially the political leader of Zionism in Palestine).
