Between 45 and 44 BC, Julius Caesar concentrated on consolidating his power and implementing a series of reforms that would profoundly shape the future of Rome. After his victory in the civil war, he was appointed dictator for ten years and later declared dictator perpetuo (dictator for life) by the Senate. This unprecedented accumulation of power allowed him to bypass traditional Republican checks and balances. Caesar expanded the Senate from 600 to 900 members, filling it with his supporters and representatives from the provinces, which diluted the influence of the old aristocracy. He enacted laws to redistribute land to veterans and the poor, reformed the tax system to be more equitable, and reduced debts by adjusting the interest rates and banning the hoarding of currency.
In addition to political reforms, Caesar introduced the Julian calendar, aligning the Roman calendar with the solar year and correcting the inaccuracies of the previous lunar system. This change improved agricultural planning and standardized timekeeping across the empire. He also initiated extensive public works projects, including the rebuilding of Carthage and Corinth, to stimulate economic growth and provide employment. Furthermore, Caesar planned military campaigns against Dacia and Parthia to secure Rome’s borders and avenge earlier defeats. However, his concentration of power and the perception that he aimed to establish a monarchy alarmed many senators. This unrest culminated in his assassination on the Ides of March in 44 BC, an event that marked the end of the Roman Republic and set the stage for the rise of the Roman Empire under his adopted heir, Octavian.
