Enclosure marshals bold new arguments about the nature of the conflict in Israel/Palestine. Gary Fields examines the dispossession of Palestinians from their land—and Israel’s rationale for seizing control of Palestinian land—in the contexts of a broad historical analysis of power and space and of an enduring discourse about land improvement. Focusing on the English enclosures (which eradicated access to common land across the English countryside), Amerindian dispossession in colonial America, and Palestinian land loss, Fields shows how exclusionary landscapes have emerged across time and geography. Evidence that the same moral, legal, and cartographic arguments were used by enclosers of land in very different historical environments challenges Israel’s current claim that it is uniquely beleaguered. This comparative framework also helps readers in the United States and the United Kingdom understand the Israeli/Palestinian conflict in the context of their own histories.
