Why did early medieval kings declare certain properties to be immune from the judicial and fiscal encroachments of their own agents? Did weakness compel them to prohibit their agents from entering these properties, as historians have traditionally believed? In a richly detailed book that will be greeted as a landmark addition to the literature on the Middle Ages, Barbara H. Rosenwein argues that immunities were markers of power. By placing restraints on themselves and their agents, kings demonstrated their authority, affirmed their status, and manipulated the boundaries of sacred space. Rosenwein transforms our understanding of an institution central to the political and social dynamics of medieval Europe. She reveals how immunities were used by kings and other leaders to forge alliances with the noble families and monastic centers that were central to their power. Generally viewed as unchanging juridical instruments, immunities as they appear here are as fluid and diverse as the disparate social and political conflicts that they at once embody and seek to defuse. Their legacy reverberates in the modern world, where liberal institutions, with their emphasis on state restraint, clash with others that encourage governmental intrusion. The protections against unreasonable searches and seizures provided by English common law and the U. S. Constitution developed in part out of the medieval experience of immunities and the institutions that were elaborated to breach them. | Negotiating Space by Barbara H.
