Finnish auxiliary paramilitary organisation for women (1918–1940s)
Lotta Svärd (Finland Swedish: [ˈlotːɑ ˈsvæːrd]) was a Finnish voluntary auxiliary paramilitary organisation for women. Formed originally in 1918, it had a large membership undertaking volunteer social work in the 1920s and 1930s. It was formed to support the White Guard. During the Second World War, it mobilized to replace men conscripted into the army. It served in hospitals, at air raid warning positions, and other auxiliary tasks in close cooperation with the army. The women were officially unarmed except for an antiaircraft battery in 1944.
