than an ecclesiastical matter, the clergy left the matter to the tsar's own decision. At noon on 24 June (O.S.), the temporal dignitaries — the 126 members of both the Senate and magistrates that comprised the court — declared Alexei guilty and sentenced him to death. But the examination by torture continued, so desperate was Peter to uncover any possible collusion. On 19 June (O.S.), the weak and ailing tsarevich received twenty-five strokes with the knout, and then, on 24 June (O.S.), he was subject to fifteen more. On 26 June (O.S.), Alexei died in the Peter and Paul fortress in Saint Petersburg, two days after the senate had condemned him to death for conspiring rebellion against his father, and for hoping for the cooperation of the common people and the armed intervention of his brother-in-law, Emperor Charles VI.
