Brian P. Levack (born 1943) is an American historian of early modern Britain and Europe. He received his B.A. (summa cum laude) from Fordham University in 1965 and his Ph.D. from Yale in 1970. In 1969 he joined the History Department of the University of Texas at Austin, where he is now the John E. Green Regents Professor in History. His research interests center on the history of the law, the relationship between law and politics in early modern Britain, the formation of the British state, witch-hunting, and demonic possession.
Levack is most widely known for his book The Witch-Hunt in Early Modern Europe (3rd edition, 2006), a comparative survey of witch-hunting throughout the early modern world that has been translated into eight languages. He has edited twenty books, including The Jacobean Union: Six Tracts of 1604 (1985) and The Witchcraft Sourcebook (2004). His most recent book, The Devil Within: Possession and Exorcism in the Christian West (2013), challenges the commonly held belief that possession signals physical or mental illness and argues that demoniacs and exorcists—consciously or not—are following their various religious cultures, and their performances can only be understood in those contexts. The recipient of a Guggenheim Fellowship in 1975, Levack was appointed Scholar in Residence at the Frances Lewis Law Center, Washington and Lee University School of Law, in 1994. At Texas he was admitted to the Academy of Distinguished Teachers in 2004, and in 2011 he received the University of Texas Regents Outstanding Teaching Award. Levack offers a wide variety of courses on early modern British and European history, legal history, and the history of witchcraft. For eight years he served as the chair of his department.
