Abstract At the end of the First World War, defeated European empires ceded a wealth of imperial patronage, including palaces, government buildings and offices, to newly forming states in central Europe. While we know a great deal about these property transfers, the fate of ceded property in mandates and other newly emerging sovereign spaces, such as international zones, is less well known. This article traces the ways in which central European properties were reallocated and sold in international zones, with special reference to the International Zone of Tangier. While the remains of central European imperialism in Tangier were integrated into the international administration, this process encouraged erstwhile imperial powers to vie ever harder to reclaim ‘their’ former property, including private property portfolios. Meanwhile, it encouraged existing imperial powers to support private property purchases in order to secure advantages in the administration. In other words, internationalization entailed widespread competition for property that is omitted from the usual accounts of these spaces. Drawing attention to this phenomenon is important as it reveals the new forms imperial rivalries took on within the international structures created after the war.
