In 1850, Franz Joseph participated…as emperor in the second of the traditional Habsburg expressions of dynastic piety: the Holy Thursday foot-washing ceremony, part of the four-day court observance of Easter.
The master of the staff and the court prelates chose twelve poor elderly men, transported them to the Hofburg, and positioned them in the ceremonial hall on a raised dais. There, before an invited audience observing the scene from tribunes, the emperor served the men a symbolic meal and archdukes cleared the dishes.
Finally, the emperor placed a bag of twenty silver coins around the necks of each before the men were led away and returned to their homes in imperial coaches.
