 Even Queen Constance, provoked by the neglect of Henry and pitying her countrymen, joined the revolts against him and besieged him in a castle, forcing him into a treaty.In the midst of preparations Henry fell ill with chills while hunting near Fiumedinisi and on 28 September died, possibly of malaria, in Messina, although it is also widely believed that he was poisoned.His wife Constance had him buried at Messina, his mortal remains were transferred to Palermo Cathedral in 1198.
