Drawing on a body of research covering primarily Europe and the Americas, but stretching also to Asia and Africa, from the mid-eighteenth century to the present, this book explores the methodological and heuristic implications of studying cities in relation to one another. Moving fluidly between comparative and transnational methods, as well as across regional and national lines, the contributors to this volume demonstrate the necessity of this broader view in assessing not just the fundamentals of urban life, the way cities are occupied and organised on a daily basis, but also the urban mindscape, the way cities are imagined and represented. In doing so the volume provides valuable insights into the advantages and limitations of using multiple cities to form historical inquiries.
