The Austrian Civil War of 12–15 February 1934, also known as the February Uprising or the February Fights, was a series of clashes in the First Austrian Republic between the forces of the authoritarian right-wing government of Engelbert Dollfuss and the Republican Protection League, the banned paramilitary arm of the Social Democratic Workers' Party of Austria. The fighting started when League members fired on the Austrian police who were attempting to enter the Social Democrats' party headquarters in Linz to search for weapons. It spread from there to Vienna and other industrial centres in eastern and central Austria. The superior numbers and firepower of the Austrian police and Federal Army quickly put an end to the uprising. The overall death toll is estimated at 350.
