The July Revolt of 1927 was a major riot starting on 15 July 1927 in the Austrian capital, Vienna. The revolt was sparked by the acquittal of three nationalist paramilitary members for the killing of two social democratic Republikanischer Schutzbund members and culminated with police forces firing into the outraged crowd and killing 89 protesters, and five policemen died. More than 600 protestors and around 600 policemen were injured.
