Otto I Crowned Holy Roman Emperor in Rome
On February 2, 962, German king Otto I was crowned Holy Roman Emperor by Pope John XII in Rome. The coronation symbolized a powerful alliance between the German monarchy and the papacy, echoing the old imperial idea of Charlemagne. Otto used the title to tighten his control over Central Europe, especially in what is now Germany and northern Italy. His reign laid the foundations for the Holy Roman Empire’s structure, which would dominate the politics of central Europe for centuries.
