iam suppose to write an essay about julius caesar tragedy using the theme loyalty but i dont know what to write about exactly can someone help ?

I can't write your essay for you but the theme of loyalty is important. Brutus is at war with himself over what to do about Caesar's rising power. Treachery is also at play here for the little meeting between the conspirators takes place. Questions of loyalty and deceit are always woven through the events of the play.
