This exploratory text proposes a US imperial ‘research perspective’ on post-war post-colonial cities – cities that the United States did not colonially occupy, i.e. not cities like Manila, 1898–1946. US imperial actors and interests helped shape such cities, and in turn were shaped by their people and structures. Importantly, the US case seems to strengthen the general recent view, also regarding formal empires, that it makes little sense to posit the existence of an imperial city type, and more sense to use ‘the imperial urban’ as a research perspective.
