In this book, Hillel Cohen, a scholar at the Harry S. Truman Institute for the Advancement of Peace at the Hebrew University of Jerusalem documents the thousands of Arabs, ranging from wealthy absentee landlords to fellahin smallholders, who sold land to Zionist organizations. He shows that everyone understood that control of land was a necessary precondition to fulfillment of national goals, both Jewish and Arab. Cohen explains the varied motives of sellers: Some wanted money, some sold land or acted as intelligence agents for the Zionists even while publicly denouncing land sales, but there were also non-monetary motivations.
