Material reconstruction after the First World War was closely linked to German reparations, yet it is curiously underrepresented in the historiography of the Treaty of Versailles as well as in studies on interwar Germany. In the Weimar Republic, political leaders, economic actors and large parts of the population supported the idea of sending building material and even labourers to neighbouring countries. This far-reaching planning process began before and continued after the signing of the peace treaty, as the Allies remained hesitant but not fully hostile to the German proposals. Material reparation potentially mobilized a wide range of goods and labour, and it was thus particularly prone to expectation, but also to disappointment in a broad segment of the population. Against the backdrop of war destruction and the international peace negotiations in 1919, this article investigates the way in which European reconstruction was discussed formally and informally in Weimar Germany. By focusing on the communicative channels and media that promoted German participation in building work abroad, it discusses how expectations were raised, managed and disappointed at the intersection of foreign and domestic policies. While there had only been minor destruction in German territory between 1914 and 1918, the republic’s political culture proved to be deeply affected by the material reconstruction on the European continent, even though most of the far-reaching plans did not result in building sites on the ground.
