Food insecurity during the First World War made hungry civilians around the continent search for alternative modes and means to fight hunger in war and post-war Europe. A transnational comparison of survival strategies, employed by individuals throughout Europe, demonstrates how ordinary civilians responded to the shortcomings of official food provisioning. The chapter explores how civilians turned to home-based agricultural production, made trips to the countryside or participated in black market. As regular circuits for obtaining food were very restricted, individuals circumvented official distribution means by relying on the alternative economies of grey and black markets. Bartering, especially, became an important means to cope with the economy of shortages. Relying on informal channels, as this chapter demonstrates, the hungry population traded jewellery for potatoes or furniture for meat. Civilians sometimes even resorted to illegal and criminal activities such as fraud and theft to meet their basic needs. In Eastern and Western Europe, individuals of course took actions in different forms, depending on the severity of the food scarcity, but, as this chapter argues, the strategies they used also shared many similar features and delineated new modes of social interactions, and new relationships to the licit and the illicit in wartime.
