This article demonstrates the connection between the ideology and activities of the Jewish Territorialist Movement and broader geopolitical trends and discourses during the late interwar and immediate post-war period. The Territorialists, active from 1934 within the Freeland League for Jewish Territorial Colonisation, were representative of such contemporary trends and discourses, especially those connected to prevailing approaches to peoplehood, territory and space. The Freelanders relied on accepted notions and practices such as colonialism and colonisation, ‘whiteness’, race, biopolitics and agro-industrial science, as well as (empty) spaces and un(der)developed territories. The Territorialists’ alignment with geopolitics makes the movement's little studied history a relevant chapter in the larger story of Jewish political behaviour. Moreover, the continuities in Territorialism's aspired social engineering project help to problematise the notion of 1945 as a turning point in twentieth century geopolitical thinking.
