Conrad's father had had him formally deposed…
1107 CE
Conrad's father had had him formally deposed at an assembly held in Mainz in April or May 1098, and his younger brother, Henry V, elected in his place.
In a letter of 1106, Henry IV admitted that Henry V's election had been opposed by many and that he "fear[ed] that there would be civil war between the two brothers and that a great disaster would befall the kingdom."
After this, Conrad could hardly influence political events in Italy.
There is no record that Urban or his successor had any contact with him, or that his father-in-law ever sent him support beyond his daughter's dowry He dies unexpectedly of a fever at the age of twenty-eight on July 27, 1101 in Florence.
There are reports of poisoning.
He is buried in Santa Reparata in Florence, now superseded by Santa Maria del Fiore.
Miracles are said to have accompanied his funeral.
According to Ekkehard of Aura, "the sign of the cross [appeared] on the arm" of Conrad's corpse, a clear indication that he was a crusader in spirit.
Ekkehard also states that Conrad never tolerated any slander against his father, and always referred to him as lord and emperor.
