The collapse of the Monarchy was preceded by mass strikes by the workforce. The one which was most successful and had the most consequences was the ‘January strike’ in 1918, which began in Wiener Neustadt on the morning of 14 January as a result of the very slow progress of the peace negotiations in Brest-Litovsk and the catastrophic food and fuel supply situation. It spread to other factories and hence paralyzed the production of material needed for the war.
