Republikanischer Schutzbund

The Republikanischer Schutzbund (German: [ʁepubliˈkaːnɪʃɐ ˈʃʊtsˌbʊnt] , "Republican Protection League") was an Austrian paramilitary organisation established in 1923 by the Social Democratic Workers' Party of Austria to defend the Austrian Republic in the face of rising political radicalisation after World War I. The Schutzbund, whose membership peaked at about 100,000 men in 1925, was armed and organised on military lines. In the July Revolt of 1927 it worked with government authorities to try to prevent the spread of violence, but it largely sat out the Pfrimer Putsch in September 1931 because it had failed so quickly.
