Final answer:
The Holy Roman Empire did not usher in an age of peace. The Holy Roman emperors had significant power but it was limited. Otto I named the Kingdom of Germany, not the Holy Roman Empire. The Roman Catholic Church and northern Europe were not united under Otto I.
Step-by-step explanation:
The question is about the Holy Roman Empire, its role in ushering in an age of peace, the power of Holy Roman emperors, the territory named by Otto I, and the union of the Roman Catholic Church and northern Europe under Otto I.
The Holy Roman Empire did not usher in an age of peace. In fact, it was characterized by conflicts and power struggles among the emperors, nobles, and other European powers.
The Holy Roman emperors did have significant power, but it was limited by the influence of other powerful entities such as the nobility and the Church.
Otto I named the territory he had conquered the Kingdom of Germany, not the Holy Roman Empire. The Holy Roman Empire was officially formed later by subsequent emperors and papal approval.
While Otto I did have significant influence and support from the Church, it is not accurate to say that the Roman Catholic Church and northern Europe were united under him.
