In the production and reception of art, processes of migration play a crucial role. This is particularly true for modernism and the historical avant-gardes of the twentieth century, when artists’ transnational networks and migrations across countries and continents greatly impacted artistic developments. Besides artists and agents such as art dealers and art historians, works of art and art institutions also migrated. For an upcoming issue of Stedelijk Studies, we invite scholars to explore forms of migration and their influence on the development and dissemination of modern art around the world from 1900–1960.
