Marc Antony did not change Caesar's will. At Caesar's funeral he read Caesar's will. Caesar's bequeathed a sum of 300 sesterces to every man in Rome and donated his gardens as public parks. Caesar also adopted Octavian and made him his heir. Mark Antony seized Caesar's money which was held at the temple of Ops. Octavian planned to accept his inheritance. Antony disapproved of this. When Octavian demanded his inheritance Marc Antony, who was the consul (head of the Republic), refused to give it to him, saying that it was public money and that it had been spent in the interests of the Roman state. He also had not disbursed Caesar's promised bequeath to the people Therefore, Octavian paid this bequest out of his own money by selling his estate and borrowing money from friend to humiliate Marc Antony and increase his own popularity. When Octavian forced the senate to nominate him consuls with the use of military threat, he was in a position of political strength with which he could get his inheritance.
At first, Antony merely uses the will as a prop to incite the mobs at Caesar's funeral. In a meeting with the other members of the second triumvirate (Act 4, Scene 1), Antony reveals that he is looking for ways to reduce Caesar's bequests to the people.
Because he loved Ceasar and had much respect towards him and he did not want Brutus or Cassius getting the will.
He wants to read it in public.
Trebonius.
He does it to fetch Caesar's will. Antony, Octavius, and Lepidus all wanted to change caesars will so that they could get more money.
Mark Antony's. He says to Brutus, "Thus, Brutus, did my master bid me kneel; thus did Mark Antony bid me fall down."
This question smells like CHEESE
He has lost an ally and is exposed to vengeful aristocrats.
Brutus and Antony.
First of all it wasn't antony's will it was Caesars will and the excuse that he gave was that he shouldnt read it to them because he didnt want them to enrage against his assasins.
Brutus fears antony
Mark Antony makes the speech of Julius' will. The will is not real, it was created by Antony himself.
Cassius
Caesar considers Antony a loyal friend despite the fact that Antony likes to stay out all night partying.
Caesars will was found in his bedroom.
Anticipation
After Julius Caesars assassination in 44BCE she had a love affair with Marc Antony, and supported him in his claim to the roman throne.
The reason Antony does this is to make the citizens/ the poor to go and against Cassius, Brutus, and the conspirators. :D
Antony would have his way with or without his approval because he is the head of the army.
