In the United States, salient issues in the field of conflict of laws date back at least to the framing of the Constitution. There was concern, for example, about what body of law the newly created federal courts would apply when handling cases between parties from different states (a type of case specifically assigned to the federal courts). Within the first two decades following ratification of the Constitution, over one hundred cases dealt with these issues, though the term "conflict of laws" was not yet used.
