This book discusses a phenomenon known as a revolution in Private International Law (PIL) or the law of conflict of laws in the United States. To be sure, the use of the term revolution in any field of law, especially one as esoteric as conflicts law is reputed to be, is hyperbolic and simplistic at the same time. Nevertheless, this term has prevailed in the literature as a shorthand description of the intellectual movement that challenged and eventually demolished the foundations of the established American system of conflicts law. Beginning in the 1960s, this movement had the appearances, and eventually acquired the dimensions and intensity, of a figurative rebellion against the established system, although it confined itself primarily to the area of choice of law in torts and contracts. This book chronicles this revolution, but also looks to the future and explores the question of what is, or should be, the next phase in the development of American conflicts law.
