Why do senators turn against Julius Caesar?

Senators turned against Julius Caesar due to a combination of fear and jealousy. Many believed he aimed to establish a monarchy and undermine the Republic, threatening their power and influence. Additionally, personal rivalries and the perception of Caesar's growing arrogance fueled resentment among the elite. The culmination of these factors led to the assassination plot, culminating in his murder on the Ides of March in 44 BCE.
