In response to the various security threats posed during World War II, known in Ireland as "The Emergency", a new reserve force – the Local Security Force (LSF) – was created on 28 May 1940 as an auxiliary police service. Instituted under a Garda Síochána Act, its activities were to be devoted to auxiliary police and internal security work. Recruiting forms were dispatched to Garda stations on 31 May 1940 and by 16 June of the same year 44,870 members were enrolled.
