During the Austrian July Revolt of 1927, 85 protesters were killed by Austrian police forces, while four policemen died, on July 15, 1927. More than 600 people were injured.

The clash was the result of conflict between the Socialist party on one hand, and on the other hand an alliance of wealthy industrialists, the Catholic Church in Austria. Both paramilitary forces had been created during the 1920s, namely the right-wing Heimwehr in 1921-1923 and the left-wing Republican Schutzbund in 1923. A clash between those groups in Schattendorf , Burgenland, on January 30, 1927 resulted in the death of a man and a child. Right-wing veterans were indicted for those deaths at a court in Vienna in July, but acquitted in a jury trial. This led to a general strike which had the aim of bringing down the government headed by Chancellor Ignaz Seipel. Massive protests resulted in a fire at the Justizpalast in Vienna. Police minister Johann Schober attempted to suppress the protests with force, which resulted in the death of the protesters.
