The National League of Women's Services (NLWS) was established in early 1917 in conjunction with the Red Cross and in anticipation of the US entering the First World War.
The League was divided into thirteen national divisions: Social and Welfare, Home Economics, Agricultural, Industrial, Medical and Nursing, Motor Driving, General Service, Health, Civics, Signalling, Map-reading, Wireless and Telegraphy, and Camping.
