Cassius!
I'm not sure about this but I think he did.
The conspiracy in Julius Caesar is moved forward in Scene 2 when Brutus is given fake letters. He then joins the conspiracy.
he is essential to Cassius because he cant do it by himself he does not have enough power or strength to get all the plans sorted out.
his name would help to make the assassination plot into something worthy and virtuous.
Cassius & the rest of the conspirators were eager to have Brutus' support because he was honored by many people at the time; they thought that this would give their cause more merit. Also, they figured people wouldn't be as quick to question their motives if an honest man like Brutus was involved.
Julius Caesar knew a guy called Brutus because he had an affair with Brutus' mother and Brutus would sometimes go to Julius' house. A rumour then began that Brutus wanted to kill a politician called Pompey, Julius helped Brutus out saying it was all a lie. Then in 44BC(the year Julius was killed), Brutus was part of a plot to murder Julius. Brutus played a major role, distracting Julius so someone could stab him in the neck.
In Shakespeare's play, Cassius is sounding Brutus out to see if he is sympathetic to the plot against Caesar.
