Opposition to Caesar’s power in 44 BC was rooted in deep-seated fears among Rome’s political elite that the Republic was on the verge of collapse. As Caesar continued to consolidate power, taking on the title of dictator perpetuo (dictator for life), many Senators and aristocrats began to see him not as a temporary leader, but as a tyrant who threatened to dismantle the Republic’s longstanding traditions. The Senate, once the heart of Roman governance, found itself increasingly sidelined as Caesar made decisions unilaterally, bypassing the checks and balances that had long defined Roman political life. This growing centralization of power, coupled with Caesar’s disregard for the Senate’s authority, led to widespread resentment among those who had once been his allies.
The fear that Caesar’s rule would mark the end of the Republic was not only driven by personal grievances but also by a genuine concern for the future of Roman governance. Many of Caesar’s reforms, while popular with the masses, were seen as direct threats to the power and influence of the Senate and the traditional aristocracy. Historians such as Suetonius and Plutarch note that this opposition was fueled by a mix of political idealism and self-preservation, as the elite sought to protect their status and the republican system that had served Rome for centuries. The opposition to Caesar’s power ultimately laid the groundwork for the conspiracy against him, as those who feared the loss of the Republic’s values began to take more drastic measures to restore what they saw as the rightful order of Roman society.
