Does Caesar die because of his arrogance or because the conspirators were more powerful?

Julius Caesar was assassinated because of his growing power over the senate. Caesar acquired numerous titles bestowed upon him by the senate. At the same time, most people in Rome believed he deserved to be king.

FLAVIUS:These people who are showing such support for Caesar Will make him think he is higher than he is, That he is above ordinary men, And he’ll keep us all in slavery and fear. Scene 1

BRUTUS:What...

Julius Caesar was assassinated because of his growing power over the senate. Caesar acquired numerous titles bestowed upon him by the senate. At the same time, most people in Rome believed he deserved to be king.

FLAVIUS:These people who are showing such support for Caesar
Will make him think he is higher than he is,
That he is above ordinary men,
And he’ll keep us all in slavery and fear. Scene 1

BRUTUS:What does this shouting mean? I’m afraid the people
Are going to choose Caesar for their king. Scene 2

The titles by the senate were mostly honorary with no real power behind them. This forced Caesar to actively campaign and clamor for more power.

Some members of the senate, including Brutus, Caesar’s longtime friend, became unnerved with the current state of affairs. These members of the senate formed the group known as the liberators and at the time their main agenda was to oust Caesar. Caesar’s appeal among the people had grown tremendously, making some of the members in the senate jealous of his achievements. However, to assassinate Caesar, they had to pretend to be doing it for the well-being of the republic. This was the sole reason that made Brutus support them.

BRUTUS:

He must die, and, for my part, I don’t know a personal cause to throw at him, But for the general complaints. He wants to be crowned.

Thus, there was no single sweeping reason to assassinate Caesar, but the most dominant of them was that Caesar became too powerful. This made him a threat to the republic, which some of the senators saw as falling to a monarchical type of rule.

CASCA:

Indeed they say that the senators Mean to establish Caesar as a king tomorrow,And that he will be king everywhere, In every place, except here in Italy.
