This is the first comparative study of Mosaic and Islamic law in American history to be published. Constructing a complex picture in trans-Atlantic, trans-European and world historical perspectives, this book elucidates the intersections that lie beneath and behind the rise of the debates in the 1990s and 2000s over the promotion of the Ten Commandments and Mosaic Law as alleged sources of American Constitutional law and symbols of American national identity. These debates have taken shape in close connection with resurgent anti-Semitism, anti-Sharia protests and anti-Sharia legislation throughout the United States and other Western societies.
