As evidenced by the radical changes to state organisation, legitimacy and the international order in the past couple of centuries with the development of nationalist ideology, nationalism inherently carries a spatial dimension that translates into an assertion for control of land. This way, it transforms the land to an ancestral national homeland rightfully belonging to ‘the nation’. But what if that land was lost to another nation? Embarking from Anthony Smith's ethno‐symbolist approach on the construction of national homelands, this article will attempt a theoretical approach on the construction of the lost national homelands. These are usually cases where military defeats led to mass expulsions of populations from their ancestral lands, while nationalist ideologies appropriated them as lost national homelands. The main argument is that the idea of the lost homelands has turned into a symbol of these nationalist ideologies and a constituent element of the respective national identities. Drawing from Greek perceptions of their lost homelands, this article will explore the mechanisms of the nationalisation of space process that elaborated the nationalisation of those homelands even after they became ‘lost’ for the Greek nation. This article contributes to the studies of the spatial dimensions of national identities, the effects of forced population transfers in identity politics and the creation of national myths and symbols.

民族主义与失落的家园：以希腊为例

在过去的几个世纪中，随着民族主义意识形态的发展，国家组织，合法性和国际秩序发生了根本性变化，民族主义固有地具有空间维度，可以转化为主张控制土地的主张。通过这种方式，它将土地转变为正确地属于“国家”的祖先民族家园。但是，如果那片土地被另一个国家失去了怎么办？本文从安东尼·史密斯（Anthony Smith）的民族象征主义方法出发，着手建设国家家园，本文将尝试从理论上探讨失落的国家家园的建设方法。在通常的情况下，军事失败导致人口被大规模驱逐出祖先的土地，而民族主义意识形态则将其视为流离失所国家家园。主要论点是，失去家园的观念已成为这些民族主义意识形态的象征，并成为各自民族身份的组成部分。本文从希腊人对其失去的家园的理解中吸取经验，探讨了太空过程国有化的机制，这些机制详细说明了那些家园被国有化的过程，即使这些家园对希腊民族来说是“失去”的。本文致力于研究民族认同的空间维度，在认同政治中强迫人口迁移的影响以及民族神话和象征的创造。
