Final answer:
During times of immediate danger, the Romans appointed a dictator, a single person with absolute authority. The dictator's role was to save Rome and step down after the crisis. Although the office had the potential for abuse, most dictators respected the temporary nature of their position.
Step-by-step explanation:
During times of immediate danger when a chief executive was needed, the Romans had the option to appoint a dictator. The dictator was a single man with absolute authority over the state for a limited time during emergencies. Their role was to save Rome from the threat and then step down, returning things to normal. Although the office of dictator could have led to a takeover, very few dictators abused their powers and respected the temporary nature of the position.
