Cities are often the central battlefields of modern wars, resulting in the massive destruction of urban structures. In processes of reconstruction, international actors initiate urban transformation in very different regions of the world, using strikingly similar patterns. But which concepts of the city do these interventions follow? Is there a special global mode of urbanisation in post-war cities, a UN urbanism? Using the examples of two post-war cities—Mostar (Bosnia and Herzegovina) and Kabul (Afghanistan)—this book aims to tackle the question of how the institutions and activities of the international community influence newly emerging daily city life. The Bauhaus Kolleg UN Urbanism has examined the influence of international aid organisations and produced design concepts for urban development in post-conflict situations that can be applied more generally.
