In Rome the Ceasar was the leader but the Senate was the power by Constitution and law. To overthrow the Senate was unthinkable until Julius declared himself a god and ruled over the Senate. However the true power wasn't Ceasar or the Senate but rather it was the mob. Rome is the mob not Centurians.
Senator Byrd and the Roman Republic:
The passing of Senator Robert C. Byrd from the American political scene also marks the departure of a great American character. This fiddle-playing high school graduate who earned a law degree at night (in 1963) and a college degree via correspondence courses (in 1994) regularly quoted the Bible, the classics, and large swaths of memorized poetry on the floor of the Senate was also a historian of the institution he loved most: The United States Senate.

Curiously, his reverence for the Senate and fierce defense of its constitutional role resulted in a most remarkable Government book on ancient Rome: The Senate of the Roman Republic: Addresses on the History of Roman Constitutionalism.
He would have much to say about the mob storming the Senate with murderous intentions based on the orders of a Ceasar.

The rewriting of history is already underway by Republicans.
The storming of the capitol is called by some "the people speak up".
