In the broadest sense, studies of constitutional doctrine and constitutional history that are sensitive to social context are studies of legal culture, although they do not necessarily use this term. Other studies deal with American culture and the Constitution more explicitly: Michael Kammen, for example, has written a history of the meaning and imagery of the Constitution in American culture—an exploration, among other things, of the symbolic importance of the Constitution in American politics and the cult of the Constitution as a "sacred" document.
