"Pray to the gods to interment the plague'' (I:1:ln 55)
Act II Sc:1
"... And therefore think of him as a serpent's egg..." (II:1:ln 32)
Act 3 Sc:1
"Et tu, Bruté" (III:1:ln 79)
What sparks the original conflict is Caesar beating Pompey's sons for the throne. The people of Rome celebrated his victory. Because of that Murellus and Flavius started conflict. They ended all of the peoples parties. This is what gets the ball rolling for the conflict. Without this no other conflict would happen.
Act IV Sc:3
"To tell thee thou shalt see me at Philippi" (IV:3:ln 283)
Brutus is considering joining the conspirators. Eventually he decided that Caesar was too dangerous to be left alone. The conspirators recruited Brutus. They discussed a lot about the plot. Brutus always got his way. Without them getting Brutus, they would not be able to kill Caesar.
Act V Sc:5
"I know my hour is come" (V:5:ln 21)
Caesar was once again warned about the Ides of March. The conspirators took Antony away to get him out of the picture. To get close to Caesar they asked him about releasing someone that he imprisoned. They killed Caesar. This is what created the main conflict.
¨Keep this man safe¨ (V:4:ln 27)
The ghost of Caesar appeared to Brutus. That provoked him to want to go to Philippi. Brutus packed up everything and marched his army to Philippi. This leads Brutus to his death. This is the start of his downfall.
Brutus realized that he was no good for Rome. He asked around for people to assist him in killing himself. Strato helped him. Thus, Antony realized Brutus had a good heart. This is what resolves the whole conflict.
The theme is to do what's best for all no matter what. Throughout the story Brutus vows to do what's best for the people. He kills Caesar. In the end he even kills himself when it comes time. Antony respects him due to that. It shows us that we need to sacrifice ourselves for the greater good.
