Relations between Deir Yassin and its Jewish neighbors had started reasonably well under the Ottomans, particularly early on when Arabic-speaking Sephardic Yemenite Jews comprised much of the surrounding population. Relations rapidly deteriorated with the growth of Zionism in Palestine and reached their apex during the Arab revolt in 1936-1939. Relations picked up again during the economic boom years of full employment of World War II. Thus, in 1948, Deir Yassin was a prosperous, expanding village at relative peace with its Jewish neighbors with whom much business was done.
