What was the key difference between the goverment of the roman Republic and the government of imperial Rome

The Roman Republic was ruled by elected leaders; Imperial Rome was ruled by leaders who inherited power. In the Roman Republic, there were written laws; in Imperial Rome there were no written laws. The Roman Republic was an indirect democracy; Imperial Rome was a direct democracy

the answer would be logic.

julius caesar turned the roman republic into the roman empire by coming in and taking the "dictator" role during the time of a civil war (elites vs lower classes) winning battles and reputation, then declaring him dictator for life

hope this : )
