The term "German Emperors" typically refers to the rulers of the Holy Roman Empire, which existed from 962 to 1806. The first emperor was Otto I, who was crowned in 962, marking the beginning of a new era in German and European history. These emperors were often elected by a group of princes and had varying degrees of power, often influenced by the political landscape of Europe. The title of emperor was closely linked to the Catholic Church, as emperors sought legitimacy through papal approval. Notable emperors include Frederick Barbarossa and Charles V, who expanded the empire's influence. The role of the emperor diminished over time, leading to the eventual dissolution of the Holy Roman Empire in 1806.
