Karl I

Karl I "the Great" (also known as Charlemagne or Karlemagnus in Frankish) was King of the Franks, and was the first individual to be crowned as Holy Roman Emperor, being crowned on Christmas Day, 800 a.d., by Pope Leo III. He waged many wars, unifying western europe into the first iteration of the Holy Roman Empire. The Empire would be split into three realms upon the death of his son, and it would not be until Otto I that the title of Holy Roman Emperor would be used again. The empire's territorial extent would not be matched again until Connor IV reforged the historical borders in 1322.
