Austria-Hungary, 1900
April 1900: Archduke Leopold Franz, the heir to the Duchy of Tuscany, has a falling out with Franz Joseph over what the proper response should be. Leopold believes that the very public shows of discontent are, surprisingly, very public shows of discontent, and thinks that Franz Joseph should induce his loyalists in both the Imperial Council and Royal Diet to introduce bills establishing basic health and safety requirements (12-hour work days, 72-hour work weeks, and stipends for the families of those who died as a direct result of actions by the employer). Franz Joseph demurres, and Leopold storms off to Bavaria.
Meanwhile, the director of the Evidenzböro, Arthur Giesel von Gieslingen, has the 2nd Brigade of the 29th Infantry Division (Austrian Landwehr) transfered to his control to better round up leftists. At the same time, the Imperial Council passes a law giving the Evidenzböro the power to try suspected anarchists within an internal court system, which Franz Joseph happily assents to.
May-November1900: A wave of reactionarism sweeps over Europe, with many governments cracking down on the revolutionary left. This is most prominent in Russia, Italy and the Balkan states, but most monarchs increase their bodyguards by at least a few men. This strikes into the upper working class as well, due to the high number of collateral fatalities in the 3 March attack and many suspected leftists are shunned and meeting places vandalized.
The initial wave of paranoia begins to die down in early July, but catches fire again when Bresci is arrested on 16 July and the resulting discovery of Anarchist cells. Suspected meeting places are stormed and set alight by panicked mobs, and countries across the continent begin either passing reforms or cracking down. After several tense months pass without attacks, the panic dies down in November.
