Otto I the Great
Otto I the Great son of Henry I the Fowler and Matilda of Ringelheim, was Duke of Saxony, King of Germany, King of Italy, and "the first of the Germans to be called the emperor of Italy" according to Arnulf of Milan.
While Charlemagne had been crowned Emperor in 800, his empire had been divided amongst his grandsons, and following the assassination of Berengar of Friuli in 924, the Imperial title had lain vacant for nearly forty years.
On 2 February 962, Otto was crowned Emperor of what later became the Holy Roman Empire.
