The Air Raid Defence League was established in February 1939, with an aim to force air raid defence as a national policy. The ARDL was open to all with an annual membership of a shilling. The ARDL sent out a monthly newsletter to members. The badge below was the second badge offered by the group (the first featured a union jack) following the incorporation of the National Association of Air Raid Wardens - the ARW standing for Air Raid Warden. With the outbreak of war the need for the group became unnecessary as air raid defence was then obviously of national importance.
