The European Yearbook of Constitutional Law (EYCL) is an annual publication devoted to the study of constitutional law. It aims to provide a forum for in-depth analysis and discussion of new developments in the field, both in Europe and beyond. This second volume examines the constitutional positioning of cities across space and time. Unrelenting urbanisation means that most people are, or soon will be, living in cities and that city administrations become, in many respects, their quintessential governing units. Cities are places where State power is operationalised and concretised; where laws and government policies transform from parchment objectives to practical realities. In a similar vein, cities are also places for the realisation of the constitutional rights and liberties enjoyed by individuals.
