Pope Benedict VI

[2] On the death of Pope John XIII in September 972, the majority of the electors who adhered to the imperial faction chose Benedict VI to be his successor.

At the request of King Lothair and Queen Emma of France, Benedict placed the monastery of Blandin under papal protection.

Led by Crescentius the Elder and Cardinal-Deacon Franco Ferrucci, who had been the preferred candidate of the anti-Ottonian faction,[7] Benedict was taken in June 974, and imprisoned in the Castel Sant'Angelo, at that time a stronghold of the Crescentii.

Hearing of the overthrow of Benedict VI, Otto II sent an imperial representative, Count Sicco, to demand his release.

Unwilling to step down, Boniface ordered a priest named Stephen to murder Benedict whilst he was in prison, strangling him to death.

Benedict VI was cardinal deacon of San Teodoro, Rome (18th century image)
