Theme

Power:
Another widely seen and used theme in Julius Caesar is the recurring idea of power. The first and most obvious instance is where the crowd offers Caesar the crown not once or twice, but 3 times. Brutus and the other conspirators see this as a grab for power, and act accordingly. They believed that by killing Caesar they were restoring power to a democratic Rome. And after Caesar was dead and gone, the conspirators struggled for power against Mark Antony and his forces. It's arguably the biggest motivator in the poem.

Manipulation:
Manipulation in Julius Caesar is arguably one of the most used themes in the whole poem. In the main conflict in the poem, Brutus and the other conspirators manipulate Caesar into coming into the senate house where he would be vulnerable. After he is killed, Mark Antony manipulates Brutus into letting him give a funeral oration to the waiting crowds in the street. Where he proceeds to manipulate the crowd with his speech, inciting them to burn down the homes of the conspirators. Manipulation is the driving force behind most, if not all of the actions of the conspirators, even against each other.
