This article explains the interest of many sectors in the legal relationship between cities and their local government. Indeed, cities themselves are beginning to use international institutions to redefine the scope of their domestic legal powers. As a result is emerging that we call international local government law. This article examines this new development with three goals: First, the document wants to demostrate that a focus on international local government law differs from other ways in which scholars have begun to think about cities and their places in the world. Second, the article wants to seek to introduced the topic of international local government law into the field of international law. The final goal, is to offer an analytic framework for evaluating the content of international local government law at this initial stage of its development.
