Answer: The assassination of Julius Caesar
Step-by-step explanation:
Julius Caesar was perhaps the most famous Roman to ever live. He was the person credited with laying the foundation for the transition of Rome from Republic to empire. Julius Caesar had grown so powerful at some point that some people in the Senate decided to kill him to preserve Roman democracy.
