Step-by-step explanation:
The Roman Empire is an early example of a republic. During the Roman Republic, citizens had the right to elect their leaders such as consuls and other officials who would represent their interests. The Roman Republic was a complex mix of democratic, aristocratic, and monarchical elements. Citizens participated in the Centuriate Assembly, elected officials annually, and had a Senate composed predominantly of aristocrats. Leaders like consuls were vested with significant power, including imperium, but were checked by term limits and the requirement to hold each other accountable. This system helped to balance power among the various factions and prevent the rise of tyranny.
