The key theme of the papers in this book concerns the prospects of building new urban environments and creating new societies in Europe during the interwar years. The contributions do not focus on the system of government – communist, fascist or democratic – but, rather, on what actually got built, by whom and why; and how the international communication of ideas was filtered through the prism of local concerns and culture. As such, the volume serves to tease out connections between urban form and social aspirations, and between the moral basis of social planning and how it was interpreted. Did the new towns of the interwar years actually create a planned society where visions met realities, aided by the design of new urban forms? This is one of the principal questions investigated by the contributors here in all the different political contexts of their chosen ‘new towns’.
