In what way did the form of the roman government change around the time of Julius ceaser?

Around the time of Julius Caesar, the Roman government transitioned from a Republic to a more autocratic form of rule. Caesar's rise to power, marked by his appointment as dictator for life in 44 BCE, effectively centralized authority and diminished the traditional power of the Senate. This shift laid the groundwork for the eventual establishment of the Roman Empire under Augustus, as it signaled the decline of republican governance and the rise of imperial rule.
