Abstract: The international influence of American (or U.S. American) constitutionalism is indisputable. The innovative framework set by the Founding Fathers back in 1787 and the resilient organizations developed thereupon had such a positive impact overseas that they were still the leading global reference 200 years after the Philadelphia Convention. Institutions such as judicial review, federalism, or even presidentialism disseminated alongside American military sway across the most varied settings and soon became unavoidable elements to consider in state-building efforts worldwide. Be it in post-colonial Latin America throughout the nineteenth century, Asia and Western Europe in the aftermath of World War II, or the emerging African nations during the second half of the twentieth century; the United States of America was for a much extended period of time the dominant prototype of a successful constitutional arrangement. Though this once hegemonic influence has somewhat lost momentum within the past couple of decades, American legal institutions enjoy to this day remarkable prestige and continue to impact significantly other systems around the globe. American courts, for instance, are still often referred to as “the most powerful and admired judiciary in the world.” Not only do they still reach more international headlines than any of their colleagues overseas, but also, as cases brought before them continue to drive many aspects of the contemporary legal debate, American judicial decisions are followed closely by foreign legal academia. So, while the new “world favorite” of democratic constitutionalism—the Federal Republic of Germany—is still relatively young and in significant ways a result of its American counterpart, the legal system of the United States is of such tradition and status that even today it takes a great share of the attention from scholars and practitioners around the globe.
