SYNOPSIS 
Act I 
The Royal Palace at Memphis; Egypt and 
Ethiopia are at war. Radames and Ramfis enter. They discuss the rumour that 
the Ethiopians are planning a new attack and Ramfis discloses that 
the priesthood has consulted the goddess Isis as to who should lead 
Egypt’s forces. He looks meaningfully at Radames, but names no-one. Alone, 
Radames muses on forthcoming glory and the chance that it may enable him to 
marry Aida, a beautiful Ethiopian slave girl. Amneris enters and asks about 
his evident happiness. She hints at a loved one in Memphis and he 
looks away. She is consumed by jealousy because she loves Radames herself. Aida 
enters and Amneris feigns kindness to her, while noticing that Aida and Radames 
cannot look at one another. 
The Pharaoh enters with the court. A 
messenger brings news of the Ethiopians’ coming attack, led by King 
Amonasro who, unknown to everyone, is Aida’s father. There is a call for 
war. Radames is named general and given the standard by Amneris. 
The battle hymn concludes and the court departs. Aida is left alone 
in confusion, unable to pray for Radames’ victory, yet, in her love 
for him, wishing his safe return. 
At the Temple of Vulcan a ritual 
is in progress. Radames is led in by Ramfis and consecrated with his 
weapons at the high altar. Both invoke the blessing of the god 
Ptah for the campaign. 
Act II 
In her apartments, Amneris awaiting 
the return of Radames, the man she loves and who has been victorious, 
and is entertained by dancers. Aida comes in with Amneris’ crown. Feigning 
kindness once again, Amneris hints that she knows Aida is in love with an 
Egyptian. She then casually mentions that Radames has been killed and Aida’s 
outburst reveals to her the truth. Admitting that she lied, Amneris cruelly 
threatens Aida who – after a moment’s defiance – vainly begs for 
forgiveness. Outside, the sound of the returning warriors is heard. 
In Thebes, the Pharaoh, Amneris, priests and courtiers await 
the arrival of Radames and his victorious army. At the end of 
a long procession Radames enters and is crowned victor by Amneris while 
the Pharaoh proclaims him the country’s saviour. Asked to name 
a favour, Radames requests the Ethiopian slaves be brought in. Aida 
recognises her father, but Amonasro whispers to her not to betray his true 
identity. To the Pharaoh he describes how he and his comrades fought 
valiantly but how their King was killed in battle. He pleads for mercy and 
Radames asks that the captured Ethiopians be set free. Ramfis opposes him, 
but eventually consents so long as the “spokesman” is kept under custody. 
The Pharaoh agrees, and then promises Radames the hand of his daughter 
in marriage. Radames will reign after him. Only Radames and Aida privately 
voice sorrow at the royal decree. 
Act III 
At night on the banks of the Nile 
the sounds of chanting can be heard coming from the Temple of Isis. 
Amneris arrives with Ramfis to spend time before her wedding in prayer and 
they go into the Temple. Aida enters to meet Radames in secret. As she 
cannot be his, she thinks of drowning herself in the Nile. But 
Amonasro appears having eluded his guard, and tells Aida that she must help her 
country in a new uprising. She must find out from Radames 
the route the Egyptian army plans to take against them. At first she 
refuses but, eventually worn down by her father, she agrees. Amonasro hides as 
Radames enters, believing that if he is successful in battle a second 
time the Pharaoh will not oppose their marriage. Aida tells him that their 
only fortune together is in flight to her homeland. Eventually he yields to 
her, and she casually asks which route the army will take to Ethiopia. As 
he tells her, Amonasro steps out of the shadows, and Radames is horrified 
to see what he has done. Both Amonasro and Aida try to persuade him to come with 
them, but Amneris comes out of the Temple followed by Ramfis. Amonasro 
tries to stab Amneris but Radames protects her. As Aida and Amonasro escape 
Radames surrenders to the guards Ramfis has called. 
Act IV 
In a hall in the Palace, 
above the underground Chamber of Justice, Amneris waits alone, torn between 
her love and a desire for vengeance. She sends for Radames and offers to 
secure a royal pardon if he will give up Aida, who has made good her 
escape. Radames refuses and Amneris sends him to his trial. Alone again she 
hears the charges against him read out and then the sentence of death. 
As Radames is led up she curses the priests’ cruelty. 
In the Temple tomb in which Radames has been sentenced to 
a live burial he awaits death. The last stone has been put 
in place when he hears a noise beside him. It is Aida who has stolen 
into the tomb to die with him. They bid each other farewell while above, 
in the Temple, priestesses chant and Amneris prays to Isis that 
Radames’ soul may rest in peace.
