Roman (Bulgarian: Роман; 930s–997) was the emperor (tsar) of Bulgaria from 977 to 991, being in Byzantine captivity thereafter still claiming the title.
We know nothing about Roman’s life until 968, when he joined his older brother Boris in Constantinople to negotiate a peace agreement between Bulgaria and Byzantium, during which they apparently served as honorary hostages at the Byzantine court.
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.
To ensure that the Bulgarian dynasty would die out (Boris II apparently had only daughters), the Byzantine emperor had Roman castrated.
Roman-Simeon received the title of patrikios and was named military governor or strategos of the theme of Abydos.
