On 26 July 1184, Henry VI, King of Germany (later Holy Roman Emperor), held a Hoftag (informal assembly) at the cathedral provostry in Erfurt. The combined weight of the assembled nobles caused the wooden second storey floor of the building to collapse. Most of the attendants fell through into the latrine cesspit below the ground floor, where about 60 of them drowned in liquid excrement. This event is called the Erfurter Latrinensturz (lit. 'Erfurt latrine fall') in several German sources.
Background
A feud between Landgrave Louis III of Thuringia and Archbishop Conrad of Mainz, which had existed since the defeat of Henry the Lion, intensified to the point that King Henry VI was forced to intervene while he was traveling through the region during a military campaign against Poland. Henry decided to call a diet in Erfurt, where he was staying, to mediate the situation between the two, and invited a number of other figures to the negotiations.
