Wars such as the First World War complicate distinctions between combatants and non-combatants. Yet several things are noteworthy and crucial to understand about gender at home in order to appreciate both the continuity and change that the First World War offered to women and men. This chapter explores several key aspects of the home front during the conflict in order to understand in detail what the war meant to those away from the primary battle zones. It examines the incorporation of the domestic sphere into the battlefront, either directly via invasion or aerial onslaught or more subtly through economic and cultural mobilisation. The chapter then traces the efforts to link the home and battle zones and some of the critical forces that destabilised both. As the war began with unprecedented mobilisation, so it ended with a more gradual and, in many cases, fraught demobilisation for both civilians and combatants.
