This is a timeline of the British home front during the First World War from 1914 to 1918. This conflict was the first modern example of total war in the United Kingdom; innovations included the mobilisation of the workforce, including many women, for munitions production, conscription and rationing. Civilians were subjected to naval bombardments, strategic bombing and food shortages caused by a submarine blockade.
