Final answer:
Otto I was the first Saxon king in Germany to resume using the title Emperor of the Romans, being crowned emperor in 962 and initiating the Ottonian dynasty.
Step-by-step explanation:
The first Saxon king in Germany who resumed using the title Emperor of the Romans was Otto I. Henry's son, Otto I, was crowned emperor in 962 by the Pope and thereby established the Kingdom of Germany within the broader realm of what was then recognized as the Holy Roman Empire. This event symbolized the continuation of the imperial tradition that Charlemagne had revived. Although Charlemagne was the first to be crowned as Emperor in 800, after his empire fragmented, it was Otto I who restored the title and initiated the Ottonian dynasty.
Otto I's rule and his crowning as emperor marked the commencement of the Ottonian period of art and architecture, which was heavily influenced by the intellectual and cultural contact with Rome. His reign, like that of Charlemagne's before him, had significant implications for the historical and cultural development of what would eventually become Germany and the broader Holy Roman Empire.
