Ron E. Hassner is an assistant professor in the Department of Political Science at the University of California, Berkeley. He is co-director of Berkeley's Religion, Politics and Globalization Program.

He is a graduate of Stanford University with degrees in political science and religious studies. His research revolves around symbolic and emotive aspects of international security with particular attention to religious violence, Middle Eastern politics and territorial disputes. His publications have focused on the role of perceptions in entrenching international disputes, the causes and characteristics of conflicts over sacred places, the characteristics of political-religious leadership and political-religious mobilization and the role of national symbols in conflict.

Professor Hassner was a fellow of the MacArthur Consortium on Peace and Security in 2000-3. In 2003-4 he was a post-doctoral scholar at the Olin Institute for International Security, Harvard University. In 2007-2008 he was a visiting professor at the Center for International Security and Cooperation (CISAC), Stanford University.

Sacred sites offer believers the possibility of communing with the divine and achieving deeper insight into their faith. Yet their spiritual and cultural importance can lead to competition as religious groups seek to exclude rivals from practicing potentially sacrilegious rituals in the hallowed space and wish to assert their own claims. Holy places thus create the potential for military, theological, or political clashes, not only between competing religious groups but also between religious groups and secular actors.

In War on Sacred Grounds, Ron E. Hassner investigates the causes and properties of conflicts over sites that are both venerated and contested; he also proposes potential means for managing these disputes. Hassner illustrates a complex and poorly understood political dilemma with accounts of the failures to reach settlement at Temple Mount/Haram el-Sharif, leading to the clashes of 2000, and the competing claims of Hindus and Muslims at Ayodhya, which resulted in the destruction of the mosque there in 1992. He also addresses more successful compromises in Jerusalem in 1967 and Mecca in 1979. Sacred sites, he contends, are particularly prone to conflict because they provide valuable resources for both religious and political actors yet cannot be divided.

The management of conflicts over sacred sites requires cooperation, Hassner suggests, between political leaders interested in promoting conflict resolution and religious leaders who can shape the meaning and value that sacred places hold for believers. Because a reconfiguration of sacred space requires a confluence of political will, religious authority, and a window of opportunity, it is relatively rare. Drawing on the study of religion and the study of politics in equal measure, Hassner's account offers insight into the often-violent dynamics that come into play at the places where religion and politics collide.
