It began with the assassination of Prince Gottschalk on 7 June 1066.[2] This took place in Lenzen.[3] According to Adam of Bremen, a priest named Yppo was "sacrificed on the altar". Several other clergy and laity were also killed. At Ratzeburg on 15 July, a monk named Ansver was stoned to death.[4] Gottschalk's widow, Sigrid, was forced out of Mecklenburg naked along with the other Christians. She and her son, Henry, took refuge at the court of her father, Sven Estridsen.[2]
Bishop John of Mecklenburg was captured in that city and held for a special triumph. He was beaten and led through various cities to be mocked before, in Rethra, his hands, feet and head were cut off.[4] According to Adam, his body was thrown into the street or perhaps into the square in front of the temple.[5] His head was affixed to a pole and offered to the god Radigast on 10 November 1066.[2]
The rebels rejected Gottschalk's eldest son, Budivoj, as prince and chose instead Kruto. Budivoj regained his throne with the help of the Saxon duke Ordulf.[2]
