Final answer:
After the fall of the Roman Empire, warrior kings and powerful groups of citizens replaced the Roman emperor. Charlemagne is an example of a warrior king who took on such a role. Elected officials also emerged as rulers in some regions.
Step-by-step explanation:
After the fall of the Roman Empire, the rulers who took the place of the Roman emperor were primarily warrior kings and powerful groups of citizens. These warrior kings were military leaders who gained power through conquest and maintained control over their kingdoms by force. Powerful groups of citizens, such as the nobility, also played a significant role in governance and decision-making.
An example of a warrior king who took the place of the Roman emperor is Charlemagne, who ruled over the Carolingian Empire in the early Middle Ages. Charlemagne expanded his territory through military campaigns and established a centralized administration that governed his vast empire.
In addition to warrior kings, elected officials also emerged as rulers in some regions after the fall of the Roman Empire. In these cases, individuals were chosen by a select group of people to lead and make decisions on behalf of the community.
