Titus Andronicus.

Having subdued the Goths, warrior Titus Andronicus returns to Rome to bury his sons, with Gothic Queen Tamora and her retinue as captives. The newly-dead Roman Emperor's two sons, Saturninus and Bassianus, are competing for their father's title. According to Roman custom, Titus sacrifices Tamora's eldest son to the Gods; having the deciding vote, he also chooses Saturninus as Emperor.
