Question

How was Charlemagne a stabilizing, or steadying force in Western Europe?

Answer 1

Charlemagne was able to unite practically the whole Western Europe and to proclaim himself the Holy Roman Emperor. By creating certain institutions he stabilized his government in the country.
Explanation:
Continuing the policy of expansion of the Frankish kingdom started by his father, during 46 years of his reign, Charlemagne led 53 military campaigns to spread Christianity and protect the Frankish state from the incursion of neighbors, but also to impose his hegemony throughout the West.
After the establishment of the empire, he focused his activity on organization, and reduced his personal share in military ventures by leaving them to his sons.
Self-taught and a lover of grammar, Charlemagne sought to promote knowledge. His desire to educate the clergy prompted cultural renewal, the so-called the Carolingian renaissance or reform.
