Republic of German-Austria
The "Reichsratsgebäude" continued to function until 1918, when the building was occupied by demonstrators during the disintegration of the Austro-Hungarian Empire. From 21 October 1918 the remaining German-speaking deputies convened in a "Provisional National Assembly", first at the "Palais Niederösterreich", from 12 November onwards in the Parliament Building. On this day the presidents of the assembly officially proclaimed the Republic of German-Austria from the ramp in front of the building. Upon the Austrian Constitutional Assembly election in 1919 and the establishment of the First Austrian Republic, the building itself was renamed the "Parlament", with the new republican National Council ("Nationalrat") and Federal Council ("Bundesrat") replacing the old Imperial House of Deputies ("Abgeordnetenhaus") and the House of Lords ("Herrenhaus").
