Final answer:
Julius Caesar's seizure of power disrupted the Roman political system and led to the end of the Republic and the establishment of the Roman Empire. Caesar's actions highlighted the weaknesses in the Republican system and centralized power in the hands of one individual, leading to a decline in political participation.
Step-by-step explanation:
Julius Caesar's seizure of power had a significant effect on the Roman political system. Prior to Caesar's rise, the Roman Republic had a balance of power between the Senate and the Consuls. However, Caesar's actions disrupted this balance and ultimately led to the end of the Republic and the establishment of the Roman Empire. Caesar's seizure of power highlighted the weaknesses in the Republican system and demonstrated that an individual could accumulate vast power and control over the state.Caesar's actions also led to a decline in political participation and the rise of autocratic rule. The traditional institutions of the Republic were weakened, and power became increasingly centralized in the hands of one individual. This change in the political system had long-lasting effects on Roman governance and set the stage for the subsequent emperors who ruled over the Roman Empire.
