In Titus Andronicus, what is the name of the emperor of Rome?

In Shakespeare’s Titus Andronicus, Saturninus is the emperor of Rome. He is the son of the previous emperor and initially competes with his brother Bassianus for succession after their father’s death.

Titus Andronicus, a victorious Roman general, refuses the throne and supports Saturninus’s claim. Saturninus is then declared emperor and chooses Lavinia, Titus’s daughter, as his intended bride, even though she is already promised to Bassianus. The conflict helps set the play’s revenge plot in motion.

Saturninus later marries Tamora, Queen of the Goths, after Titus’s family conflict with him. Tamora becomes Empress of Rome and uses her influence to pursue revenge against the Andronici. Saturninus’s rule grows increasingly violent: he condemns Titus’s sons, orders punishments, and ultimately kills Titus before being killed himself by Lucius. Lucius then becomes emperor. Lucius, Marcus, and Titus are important Roman figures, but none is emperor during most of the play; Saturninus is the canonical answer.
