One of the most grievous outcomes of the Arab revolt (1936-1939) was the severe economic damage caused to the Arab community. The worsening relations between Jews and Arabs from the start of the 1936 disturbances and thereafter had distinct consequences regarding the decline in Jaffa`s economic state. The slump that affected Jaffa from 1936 to the end of the mandate period encroached on the city`s status and strength, as its weaknesses became more marked. The basic premise is that the Jews had a significant role in Jaffa`s economic decline, principally due to their preponderance in the city`s commercial life. The lecture seeks to present the expressions of the economic decline in the years from 1936 to 1947, and to examine how the Jews influenced it. It is argued that the Jews proved a significant factor in the city`s economic decline, with evident repercussions for Jaffa`s situation toward the end of this period.
