1. Removing Decorations: Marullus and Flavius take down and destroy the decorations that the citizens have put up to honor and celebrate Julius Caesar's triumphal return to Rome. By doing so, they are symbolically undermining Caesar's popularity and reducing his image as a conquering hero.
2. Public Speeches: Marullus and Flavius address the common people (plebians) of Rome and question Caesar's motives and ambitions. They point out how he has become too powerful and is seeking to become a king, which goes against the principles of the Roman Republic. Their speeches plant seeds of doubt in the minds of the citizens and create a negative sentiment against Caesar.
3. Political Subversion: Marullus and Flavius engage in political subversion by inciting the common people to rebel against Caesar and his policies. They take advantage of the people's discontentment and use their positions as tribunes to challenge Caesar's authority.
4. Public Humiliation: Marullus and Flavius publicly humiliate Caesar by arresting and punishing a cobbler named Cinna because he accidentally mistakes Cinna the poet for Cinna the conspirator. This act, while initially amusing to some, ultimately discredits Caesar and his administration in the eyes of the public.
5. Challenging Caesar's Authority: Marullus and Flavius openly defy Caesar's authority by ignoring his decree that no one should speak negatively of him. They continue to criticize Caesar and highlight his flaws, further eroding his reputation and popularity among the people.
By taking these actions, Marullus and Flavius indirectly contribute to the events leading up to Caesar's assassination and hinder the victory of Caesar and his supporters.
