Святослав Игоревич
In Bulgaria Roman probably shared his brother’s destiny, becoming first a pawn in the hands of Prince Sviatoslav I of Kiev and then in those of the Byzantine Emperor John I Tzimiskes. After the latter’s victory in 971, Roman was taken to Constantinople together with his brother’s family. To ensure that the Bulgarian dynasty would die out (Boris II apparently had only daughters), the Byzantine emperor had Roman castrated. Boris and Roman remained in honorary captivity at the imperial palace until after the death of the emperor in 976.
