Henry III (1017–1056) was King of the Romans from 1039 and Holy Roman Emperor from 1046 until his death. A member of the Salian dynasty, he presided over a period of strong imperial authority and played a decisive role in reforming the papacy in the mid-eleventh century.

His reign represents the high point of imperial influence over the Roman Church before the upheavals of the Investiture Controversy ⓘ.

Consolidation of Power

Henry succeeded his father, Conrad II, Holy Roman Emperor, in 1039. Already crowned king during his father’s lifetime, he inherited a stable and expanding realm. He maintained firm control over the German duchies and intervened actively in Burgundy and Italy.

Henry strengthened royal authority by overseeing episcopal appointments and relying on a loyal episcopate to reinforce imperial administration.

Intervention in the Papacy

In 1046 Henry travelled to Italy amid scandal and division within the Roman Church. Three rival claimants—Benedict IX, Sylvester III, and Gregory VI—were competing for the papacy.

At the Council of Sutri, Henry oversaw the deposition of all three and secured the election of Suidger of Bamberg as Pope Clement II, who crowned Henry emperor later that year.

In the years that followed, Henry continued to influence papal elections, supporting reform-minded candidates such as Leo IX. His intervention helped initiate the movement that would later evolve into the Gregorian Reform ⓘ.
