St. Stephen's Cathedral, Vienna
As a result of the 1848 revolutions, the Federal Convention of the German monarchs, who had continued the use of the Imperial Eagle coat of arms in 1815, also adopted the tricolour ("from German time immemorial") in order to steady the nationalist unrest. Emperor Ferdinand I of Austria had the Black, Red, and Gold flag hoisted on St. Stephen's Cathedral, Vienna and showed himself with the flag on a window of Hofburg Palace. In Berlin, King Frederick William IV of Prussia had to bow to the fallen insurgents of the liberation movement and to wear a Black, Red and Gold armband while riding through the city.
