I saw this mentioned in passing and thought it was unusual enough to share here. There’s a metaphor in there somewhere…

Emperor Heinrich VI

In July 1184 Henry VI, King of Germany (later Holy Roman Emperor), held court at a Hoftag in Erfurt. On the morning of 26 July, the combined weight of the assembled nobles caused the wooden second story floor of the assembly building to collapse and most of them fell through into the latrine cesspit below the ground floor, where about 60 of them drowned in liquid excrement. This event is called Erfurter Latrinensturz (lit.‚ÄČ’Erfurt latrine fall’) in several German sources.
